Car not shaking!
|
Silver Member Username: TdbdrummerPost Number: 273 Registered: Feb-05 | Ok, I am running my Audiobahn A8000T amplifier with my 2 Volfenhag subs, and I've noticed that from the inside of the car, the bass is really incredible for the price I paid on the subs (Sounds good too!), but for some reason no matter how high I crank the gain/volume/bass boost I can't hear my car rattle. I have on '02 Mercury Cougar. What's the chance my car has some type of dampening system already built in? I have heard people with MTX and Sony subs make their cars vibrate from the outside, and we all know how bad Sony subs are, and I can't say I've been impressed with MTX's subs either. I can make things like the rear view mirror go from facing straight up to fall straight down, but the bass can't really be heard with all doors and windows closed. I have my subs in a sealed bos for SQ purposes rather than effieciency of power. Also, today my friend had a bass test cd that played all frequencies of bass, and my subs didn't seem to drop out until around 30Hz or so, what they say they play. Yet, my friend (Who lives for Sony 6x9's and 6.5's) says my subs are terrible and don't "hit" hard enough. I do know one thing, he was listenin to them in open air. He didn't actually get INTO the car close doors and windows and listen. But even when we were listening from outside the trunk with it open, the bass was so powerful that it made it hard to decipher what we were saying as it would "cut" our voices in and out like we were covering and uncovering our mouths while we talked. What am I doing wrong? I still have a stock HU, but am looking into buying something from the Kenwood series, most likely the EZ-700 I believe it is. |

allende5 Unregistered guest | Ummm....you `want` your car to vibrate and rattle? Heck, I'm trying to find ways to 'stop' mine from vibrating. I don't know about everyone else, but I think it sounds like crap when a car pulls up next to me at a stop and all I can hear is the car rattling. I don't get it. I say, take the great sound quality and run! |

Bronze Member Username: Dano9258Post Number: 38 Registered: May-05 | I would agree. I just got a new MTX 5601D AMP to power my two audiobahn 12" subs. It really booms, but the rattling is horrible. Is there a way to stop it? |

Silver Member Username: Rds11Louisville, Kentucky Post Number: 249 Registered: Nov-04 | UM.. Iv heard of DYNAMAT, but then again there are so many other dampening brands out there now maybe there is one called dynamite. |

Bronze Member Username: ShadylimitedxPgh, Pa Usa Post Number: 62 Registered: Apr-05 | y would u want ur car rattle mine rattles like a b***h an its so annoying with just 1 volfenhag in a ported box with a 760pioneer amp iam thinkin of gettin 56sq ft of edead for about $105 with shippin |
|
Silver Member Username: GoonPost Number: 203 Registered: Feb-05 | edead is the shiat...dynamat is well worth it too, if the oney isn't a big option. if money is...edead is great. a freidn of mine put it in his car, makes a good difference. |

Gold Member Username: CarguyPost Number: 2979 Registered: Nov-04 | "DYNAMITE" sounds like a permanent way of getting rid of your rattles along with everything else including your car!  |

Bronze Member Username: Daddy_phat_sackPost Number: 53 Registered: May-05 | lol isaac.... and ive never heard of dynamite either.... but yea u dont want ur car to rattle..... maybe flex a lil bit but not rattle... |

Silver Member Username: TdbdrummerPost Number: 274 Registered: Feb-05 | Ah, so you think your Volfenhag is powerful enough? I don't want my car to rattle, but my friend thinks that my subs dont "hit", as he puts it, hard enough, because with the car closed up you hear nothing, even at extremely high levels. I was just wondering if anyone else has had experience with my subs/amp, and although I use a sealed box, I feel that I'm getting enough bass. I could use a cap/new alt for a little help with power, but I know im getting at LEAST 650W out of it. Is there any way to measure my dB rating as well? I probably don't have the best imaging since I have four 5x7 door speakers, two front, two back. But either way, I get PLENTY of sound for me, and probably more with a good HU. |

Bronze Member Username: Adelphia83Colorado Springs, CO USA Post Number: 32 Registered: May-05 | Thinking back to my last system, I had two Audiobahn Alum12's in a sealed box, with a measly 240w/channel in a 1986 Toyota Tercel. In that car *EVERYTHING* rattled, and the bass could be heard from a block away. I've sinced upgraded to a better system (A8002T amp w/ 2x AW1200Q woofers in ported box) in a newer car (2001 VW Jetta GLX), and I've come across the same problem so to speak. The sound doesn't carry nearly as much outside the car, but is FAR louder than my old system. Even the vibration is less than my old car. I think it really depends on the car, and how you have the woofers oriented. I have my subs facing upwards toward the rear deck (my boxes don't fit in the trunk otherwise). The amount of bass that plays outside the car is really a moot point. It depends on how you're satisfied with both the volume and sound quality within the car itself, where you're sitting. |

Bronze Member Username: Msully701Stratford, Connecticut US Post Number: 87 Registered: Apr-05 | well as a owner of two 12" L7's in a ported box I get plenty of rattle, if the sun hits my mirror to much im supprize the damn thing wont fall off with all the shaking its doing, I actually bought felt pads to put behind my license plate so theres not much rattleing anywho I dont even want to do sound deadening because when I pull up next to someone and my cars shaking they know that I got some goods and its the hizzle fo chizzle, anyway you cant get too much car shaking from sealed box and subs that you have, if your into shaking and SPL then get a ported box, dont know how you have RCA"s running from a stock HU usually they dont have them, im not sure how good you are on wiring but if could be wired wrong, therefore not giving them enough bump. also what size are the subs and how much RMS watts can they handle? |
|
Silver Member Username: TdbdrummerPost Number: 275 Registered: Feb-05 | I gotta ask, why do you people buy the A8002T instead of the A8000T? A mono amp CAN run two subs just as effectively as a 2 chan. amp! |
|
Silver Member Username: TdbdrummerPost Number: 276 Registered: Feb-05 | The subs are 500W RMS, and wired in parallel for 2 ohms to my amp. I know I've pushed these things close to 800W before, with minimal distortion, caused mostly by a sealed box. My stock HU didn't have line output, I had to put in a LOC. The subs are 12 inches. I would have gotten Kicker, but boxes with subs wouldn't have fit! |
|
Silver Member Username: TdbdrummerPost Number: 277 Registered: Feb-05 | Exactly what is wrong with my subs? This could be a lie from the company, but they are "as they put" rated as "competition" subs. I don't know whether their competition comes from their good sq or their power. |
|
Bronze Member Username: Msully701Stratford, Connecticut US Post Number: 89 Registered: Apr-05 | sealed boxed are for SQ, if you want rattle get a ported box I dont think anythings wrong with your subs or the amp and the wiring seems right, If your getting a new HU that might help so If you have problems after the new HU post again. and about the 2 channel thing most people dont know how to wire correctly so they see 2 channel and its much easier to wire, me personally im running a kicker kx1200.1 to two 12" L7's and I just had to wire em right, people buy that stuff because its simpler and easy it really makes no difference which one you buy just the wiring they both push the same watts ect.. |
|
Gold Member Username: CarguyPost Number: 2982 Registered: Nov-04 | TB if you're using LOC then you won't get much bass as the volume increases. Maybe that's why you're not being heard outside the car. To get trunk rattling bass, you need rca out from your HU. |
|
Bronze Member Username: Msully701Stratford, Connecticut US Post Number: 90 Registered: Apr-05 | and just because they say "competition subs" doesnt mean much most the time its a selling gimic they use to get the fools who dont know anything about subs and im not saying your one just answering |
|
Bronze Member Username: Msully701Stratford, Connecticut US Post Number: 91 Registered: Apr-05 | yeah Isaac is right, it might not be running your amp correctly either |
|
Silver Member Username: TdbdrummerPost Number: 278 Registered: Feb-05 | I was looking to get this HU: http://www.crutchfield.com/S-Ln2FuaJdgy0/cgi-bin/ProdView.asp?g=300&I=113EZ700SR Would that HU give me everything I need and then some? |
|
Gold Member Username: CarguyPost Number: 2985 Registered: Nov-04 | TB, that HU will do everything you're looking for. It is even Satellite radio ready. The only bad thing about it is, it requires $12.99/month subscription before the unit works. That is g.a.y. No company should force anyone to pay to use a product that you've already paid for. Read the bolded text, the HU will NOT work till you subscribe. You might want to look for a different unit/brand. |

Bronze Member Username: Adelphia83Colorado Springs, CO USA Post Number: 33 Registered: May-05 | To answer the question, "I gotta ask, why do you people buy the A8002T instead of the A8000T? A mono amp CAN run two subs just as effectively as a 2 chan. amp!" A) A8002T was 30$ cheaper. B) The two subs I had purchased were 4 ohm DVC. Which means I wire VC's in series (creating an 8 ohm woofer), and then both woofers in parallel (creating a 4 ohm mono load). The A8002T pushes 800W RMS to a 4 ohm mono load, as opposed to the A8000T's 400W RMS 4ohm mono. C) You do the math --> A8002T is good for 2ohm stereo or 4 ohm mono.. A8000T is good for 2 ohm mono (arguably a better sub amp, but be aware that there are some damn good subs that are wired for 4-ohm DVC, which when used in pairs cannot be used efficiently with the A8000T amp, but better used with the A8002T). D) this ain't rocket science. |

infinity addict Unregistered guest | open your windows? ;-P I, personally, hate rattle. I laugh at little rice rockets whose trunks shake so much. i also think it's annoying and doesnt look good on them. when i got my first pair of subs i went all around my car (inside and out) tightening every screw and bolt. I even took a door apart cuz the locking mech was rattling. anyways, thats just my perspective. i still havent taken care of all the rattle. i gotta take care of the hatchback, its the biggest and last problem. |

Bronze Member Username: Daddy_phat_sackPost Number: 83 Registered: May-05 | i have a hatchback.... will it rattle a whole lot when i install my subs???? their 2 kicker comp vrs 12s |

Silver Member Username: TdbdrummerPost Number: 279 Registered: Feb-05 | I'm going to go for the next lower model for the HU's from Kenwood, does what I want, and I can get the satelite if I WANT to and the HU will still work. Well either the EZ-500 or the KDC-X789. One is far more expensive than the other (100 bucks!) but the watt output is the same. I still may go with the more expensive one! http://www.crutchfield.com/S-ayfWkOXMHB3/cgi-bin/ProdView.asp?g=300&I=113EZ500 http://www.crutchfield.com/S-ayfWkOXMHB3/cgi-bin/ProdView.asp?g=300&I=113KDCX789 |

Gold Member Username: CarguyPost Number: 2995 Registered: Nov-04 | TB, go with the X789. It has parametric equalizer. |
|
Silver Member Username: TdbdrummerPost Number: 280 Registered: Feb-05 | Is that the same as a graphic equalizer? |
|
Gold Member Username: CarguyPost Number: 2997 Registered: Nov-04 | Yes but is much better. |

New member Username: Yeah_toastBIG SB South Bend, IN USA Post Number: 1 Registered: May-05 | Ok i got a station wagon and i hate rattle too. I was wonderin on how to stop the roof from rattling. what im saying is when i turn my subs up the roof actual noticably viberates like crazy will dynamat or somtin maybe cheaper help this there is no support in the middle nor real support i could weld or screwsomtin in for reinforcement. |
|
illusionstudios Unregistered guest | brian adding mass gets rid of raddles or vibration - dynakmat works but costly - you can try the cheep route go to the depot or lowes get rubber mat they put on floors or in tool boxes a little spray adhesive see if it works - yes i have done it - yes it did work |

Gold Member Username: HdubbFarmington, Nm Usa Post Number: 1511 Registered: Nov-04 | tb you are a very strange individual. thats all i have to say, if you want your car to rattle play lower bass notes if your subs can handle it |
|
Gold Member Username: CarguyPost Number: 3002 Registered: Nov-04 | Hunter, it's like this, those that have rattle hate it, and those that don't have it, want it. Go figure. |
|
Silver Member Username: TdbdrummerPost Number: 281 Registered: Feb-05 | I DON'T want rattle, but my friend made me feel like my whole system was garbage because the car DIDN'T rattle. I know it sounds good, but he, being a Sony lover, thinks everything needs to XPLOD! Hehehehe...no pun intended! |
|
Silver Member Username: TdbdrummerPost Number: 282 Registered: Feb-05 | My subs play clear down to either 30 or 32 Hz. Really, I don't need much lower since the lowest music I listen to is Jazz and Chevelle. And they are LOW! |
|
Gold Member Username: InvainMichigan United States Post Number: 2616 Registered: Aug-04 | Honestly, just screw your dumb friend. As long as your system sounds good and loud on the insde, then you should be happy. I woulda loved if if my system wouldn't have been able to be heard form outside the car. Seriously, there's a lot of people that don't want to hear your music, and just because you can hear your car from a block away isn't that impressive, nor even that hard. Keep the sound in man. |

Silver Member Username: SolacedagonyNew Jersey US Post Number: 446 Registered: Oct-04 | Professional systems that run insane SPLs and are professional sound deadened are completely or mostly silent with everything in the car closed up. |
|
seeingDER Unregistered guest | Chevelle gets low? Which song? |
|
Silver Member Username: TdbdrummerPost Number: 302 Registered: Feb-05 | Comfortable Liar. Extremely low. |
|
Bronze Member Username: NitescortPost Number: 78 Registered: Mar-05 | AudioBahn subs ARE competition subs. however in every competition someone has to come in last. |
|
Gold Member Username: HdubbFarmington, Nm Usa Post Number: 1549 Registered: Nov-04 | yeah chevelle does get low, on the first song on their new album they have a sweep dont know how low it goes but it is low |
|
Silver Member Username: TdbdrummerPost Number: 310 Registered: Feb-05 | Yea, I love their bass sweeps. Some of their bass reminds of rap bass at times, but it's different. |
|
seeingred Unregistered guest | cool.. i'll have to listen to them again once i get my subs in! First track of their new album is.. 'The Clincher' i think.. |
|
Silver Member Username: TdbdrummerPost Number: 312 Registered: Feb-05 | The Clincher is from their 3rd album! If you want a really good quick bass sweep listen to Say It (track 4) on that same CD. It has that "disclaimer" part then a huge pound of bass. I think lol! |
|
Silver Member Username: TdbdrummerPost Number: 313 Registered: Feb-05 | Haha, also, I got my car to rattle. I put the amp at half gain, and set car (stock) stereo at full bass boost and half volume as well. Yea, trunk rattled. That's with stock too! I know once I get rid of that stock HU I'll get rid of most clipping it sends to amp to subs too! But yea, I rattled...wasn't a huge deal...kinda irratated me, I thought my car was impenetrable! |
