Sub Box Direction

Bronze Member Username: RwellsAtlanta, Georgia United States Post Number: 37 Registered: Mar-06 | I got a Acura Integra with 2 12" CVR's. i have my subs facin the back of the car toward the exaust. But im startin to think maybe i should have it facin the other way, and maybe that might help trunk rattle too since i ride with the back seat down! what do you think??? |

That is the best configuration (there are tests that prove it). Buy mad ft² edead and put multiple layers on your trunk lid (get a roller tool, helps a LOT), and make sure you overlap it onto the edges that actually touch the bottom of the trunk seal opening when its closed, this will allow the trunk lid to close down tighter, due to the increased thickness around the edges of the trunk seal. |

Silver Member Username: LewassBoomfield Hills, MI USA Post Number: 479 Registered: Jan-06 | K let me do some googling. It was independent testing done by some guys at a car audio shop back in 2003... They tested like 4 or 5 different cars with different types of trunks.. OK here it is: www.installer.com/tech/aiming2.html |

Post Number: 6969 Registered: Jul-05 | apart from 'those tests' experiementing on ur own & experience will prove that it does sound ALOT better hands down if facing backwards . However if ur trunk is rattling like hell & u dont want 2 sound deaden 4 some strange reason then face up or even forward ...... |

Silver Member Username: LewassBoomfield Hills, MI USA Post Number: 480 Registered: Jan-06 | You would sacrifice bass for less rattling. You would never want to do that. Louder bass will make more rattles. |

Gold Member Username: RovinTrinidad & T... Post Number: 6976 Registered: Jul-05 | "You would sacrifice bass for less rattling" - yep thats what happens if u face up/front , it depends on if u do not want 2 s/deaden or too lazy or too cheap ....... |

Silver Member Username: Langless28Boston, MA Post Number: 438 Registered: Dec-04 | thanks for the site on the test, but all the losses seem to happen around 100hz, i dont think many people run this subs at that high of a fq my cross over is set at like 70 or 80 cant member so i shouldnt have a problem, i wanted to face mine towards the backseat (for a stealth look) |
|
Bronze Member Username: RwellsAtlanta, Georgia United States Post Number: 41 Registered: Mar-06 | ill just duy some deaden! cause i defeinately dont want to lose bass...thnx every1 o and with the deaden,, do i need to buy both the paint on stuff that is like paint, AND the mats? |

Silver Member Username: LewassBoomfield Hills, MI USA Post Number: 494 Registered: Jan-06 | Rovin: Yeah I'm totally with ya, but from a practical standpoint, why would anyone ever want to do that? bassfishing: No, the biggest losses are around 100 hz, but the curve is lower throughout the entire frequency response... with every single car tested... some more drastic than others. If you don't want your trunk to rattle, get shittier subs, or sound deaden. In my opinion it is wasted money to buy expensive subs only to run them in anything but the optimum configuration. Also, how can anyone expect to have a killer setup without the use of any sound deadening? |

Silver Member Username: LewassBoomfield Hills, MI USA Post Number: 495 Registered: Jan-06 | Just make sure you get peel and stick sound deadening, otherwise you will have a huge project on your hands.. But yes using both does help to really do the job well... It all comes down to how important is it for you to not rattle. I've also found that expanding foam does wonders for those out of sight out of reach places... |
|
Bronze Member Username: RwellsAtlanta, Georgia United States Post Number: 42 Registered: Mar-06 | when you say expanding foam, you are talking about that stuff in a can that you spray and becomes a hard foam?? does it really work? i thought about that but i just wasnt sure if it would work! |
|
Silver Member Username: LewassBoomfield Hills, MI USA Post Number: 502 Registered: Jan-06 | Yep, thats the stuff. If you use a long straw or tube that allows you to pump it into hard to reach places, it can be great to stop those impossible rattles. It works totally different than dynamat does though, whereas dynamat and other peel and stick products actually add mass and convert vibration to heat energy, the expanding foam does nothing but physically hold 2 offending objects from rubbing eachother. So you need to be smart when using it, and also be careful, because when it dries, it can be a pain in the azz to remove. |

Bronze Member Username: RwellsAtlanta, Georgia United States Post Number: 43 Registered: Mar-06 | i just put a can on that i had layin around the house. ill let it dry and if i can tell the slightest differance than i will go to home depot and buy some more and fill the whole trunk up with the sh!t. im a student on a very small budget and i hate to admit i cant even afford spendin 50$ for some deaden at teh moment. the foam will be a temp solution though until i get some money! |

Silver Member Username: LewassBoomfield Hills, MI USA Post Number: 503 Registered: Jan-06 | Don't just spray it on your trunk, it needs to be used only in certain spots, like behind a tail light casing... You gotta use peel and stick for the trunk lid and major surface areas |

Gold Member Username: B101Queen City, NC USA Post Number: 2164 Registered: Sep-05 | my subs, are facing into the cab, I must say, the bass will knock the snot out of your nose... Its also extremely loud on the outside of my vehicle!! The bass all depends on your vehicle and the shape of it= resonating frequency; also these test performed isnt too accurate at all.. he had sub facin inward, with the back seat up??? < what is that proving? It better sound better the other way, with space in front of it, pointed toward the exhaust...  Then some of the test are in suv... so thats a HUGE diffrence!! |
