Silver Member Username: Gcs8Atlanta, Ga Post Number: 575 Registered: Sep-09 | so to all the other FI owners out there do they all start so stiff that they barely move or make a sound out of the box? like i haft to give the poor thing CPR to make it move at all. |

Diamond Member Username: WingmanaliveWww.stainles... .ecrater.com Post Number: 22921 Registered: Jun-06 | Stiff maybe. Dead no. It will loosen a bit over time but it shouldn't act lame out of the box. How long have you run it? |

Silver Member Username: Gcs8Atlanta, Ga Post Number: 576 Registered: Sep-09 | ~20 min on 2 diff amps and blown 2 sets of fuses. and it didn't get any louder then my cell on vibrate but it does make the wires connecting the voice coils "dance". |

|
Silver Member Username: Gcs8Atlanta, Ga Post Number: 577 Registered: Sep-09 | no i know y i am blowing fuses, its cuz i am trying the tune by ear route cuz my amp in the car was set with a dmm for 2 ohm's, but beacouse it was making so little sound i decided to cut the gain up a little, the fuses are my fault but i doubt the sub barley making any noise is. tried it on 2 diff amps. |
|
Silver Member Username: CwruckPost Number: 237 Registered: Feb-10 | maybe becuase its at a .5 ohm load? isn't that what you said it was wired at? Wire it in series even if your dmm said it was still at .5 that sucks your having trouble |
|
Silver Member Username: Gcs8Atlanta, Ga Post Number: 578 Registered: Sep-09 | i think my dmm is F'ed. it is wired for 2 ohm's right now not .5. i am not a total noob, all tho the guys on the FI form seem to think i am. hears the link http://www.soundsolutionsaudio.com/forum/impedance-fail-t41319.html&gopid=669500 #entry669500 |

Silver Member Username: CwruckPost Number: 239 Registered: Feb-10 | ya man i figured you did that, just don't know what could be the problem. And i can't see any posts on that forum since im not registered |

Silver Member Username: Gcs8Atlanta, Ga Post Number: 579 Registered: Sep-09 | NDMstang65, on 14 June 2010 - 07:03 PM, said: You're probably running on a stock electrical system too... Those coils are wound on a machine that has a very specific length of wire that is calculated to be exactly .75 ohms. You are not going to have one coil .5 ohms and one .75 ohms...it's impossible. You cannot put that kind of power in a stock car with a stock electrical system and yank the gains up and expect magic to happen... It takes power to make power. -------------------------------------------------------------------------------- ---- i know it takes power to make power, this is by far not my first system. i also under stand that the gain is not a vol knob. the subs i had in there before where 1.8 ohm's and so i thought .75 + .75 = 1.5 so not that far off. when it didn't sound louder then my phone on vibrate i turned the gain all the way down then slowly turned it up (tune by ear instead of with my dmm) thats when my fuse blew. i am running simi stock electrical, big 3 is done, with the gain set at ~ 1450 by the dmm it ran fine for quite some time. at my max vol 45 of 62 the voltage didn't drop below 13.1V in the back, electrical up grades are on the way as i get more money. and i do keep the sub lvl at -3db at the HU. i don't have ~150 amps to feed it but i do have enof to run it at around ~100 amps. |

Silver Member Username: Gcs8Atlanta, Ga Post Number: 580 Registered: Sep-09 | i know my electrical is weak sauce so i try and make it where the sub only see's ~1000 watts at my max vol of 45 out of 62. |

Gold Member Username: SouthernrebelMonroe, Louisiana Team Audible... Post Number: 8080 Registered: Mar-04 | what sub? if it is not moving at all, or very little...i bet you have the coils out of phase pull the sub and use a battery (9v or even a drill battery) and pop the coils. Make sure you have them wired right. then free air it. one coil at a time. |
|
Silver Member Username: Gcs8Atlanta, Ga Post Number: 581 Registered: Sep-09 | ok i will try that and its a FI Q 15 it just came in to day. i have it wired in series atm will pull it and bring it in side to my test bench. |
|
Silver Member Username: Gcs8Atlanta, Ga Post Number: 582 Registered: Sep-09 | well canaan looks like you may be right one coil pulls one way the other one pushes and it plays on on one coil. now what? |
|
Gold Member Username: SouthernrebelMonroe, Louisiana Team Audible... Post Number: 8081 Registered: Mar-04 | Well, the leads under the dust cap may be soldered incorrectly. Or the terminals are just mislabeled. Use a battery to check polarity and label what terminal is + and what is -. Then use that as reference to wire the sub correctly. You will be up and running then. |
|
Silver Member Username: Gcs8Atlanta, Ga Post Number: 583 Registered: Sep-09 | ok let me try that, i will get back to you in a sec |
|
Silver Member Username: Gcs8Atlanta, Ga Post Number: 584 Registered: Sep-09 | parallel = ok series = fail |
|
Silver Member Username: Gcs8Atlanta, Ga Post Number: 585 Registered: Sep-09 | and the coils look like there wired like there suppose to be. |
|
Gold Member Username: SouthernrebelMonroe, Louisiana Team Audible... Post Number: 8082 Registered: Mar-04 | make sure you have the series wiring done right. go by your NEW terminal designation. If parallel is working, series should also. What does each coil read individually? You may have damaged a coil having it wired incorrectly to begin with. |
|
Silver Member Username: Gcs8Atlanta, Ga Post Number: 586 Registered: Sep-09 | well i think the coils are ok not sure... if + termnal to + batt and - to - cone moves up same for both sides. what does this mean? |
|
Gold Member Username: SouthernrebelMonroe, Louisiana Team Audible... Post Number: 8083 Registered: Mar-04 | it means the coils are labeled correctly. Not messed up like I originally thought. grab a DMM and check the resistance on each coil. |
|
Silver Member Username: Gcs8Atlanta, Ga Post Number: 587 Registered: Sep-09 | yah that part of my DMM seems to not be working like its suppose to i read .7 on one and .5 on the other when i unboxed it but no matter how i wire it it reads .5 or .3 |
|
Silver Member Username: Gcs8Atlanta, Ga Post Number: 590 Registered: Sep-09 | ok so i found out i am retarded, was treating the coils as if they where 2 sepret subs... seems fine now. |

Silver Member Username: Gcs8Atlanta, Ga Post Number: 591 Registered: Sep-09 | ty ty my title as the village idiot stands. thanks for all who contrubited, now any one know what i should set my saz-3000D at for 1.5 ohm's? |
|
Silver Member Username: CwruckPost Number: 244 Registered: Feb-10 | I bet a quarter gain is too much! haha |
|
Silver Member Username: JbpittPittsburgh, Pa. Usa Post Number: 437 Registered: Jul-09 | You get everything straighted out yet? |
|
Gold Member Username: BonhamdTraverse City, MI Post Number: 2202 Registered: Nov-07 | use your dmm to set your gains. its not fool proof, but its better than you setting it by ear. if you cant figure out coils you probably shouldnt set your gains at all why ruin nice equipment? |
|
Silver Member Username: Gcs8Atlanta, Ga Post Number: 592 Registered: Sep-09 | yah sean p i got it happy, just trying to figger out how much power to set the saz-3000d for a 1.5 ohm load or just set it for a 2 ohm load and for get about it. |
|
Silver Member Username: Gcs8Atlanta, Ga Post Number: 593 Registered: Sep-09 | well almost no one in my area has a 125 amp ANL fuse so i have no power.... |
|
Gold Member Username: BonhamdTraverse City, MI Post Number: 2212 Registered: Nov-07 | youre running 4 gauge to a saz 3K? holy sheepdick get bigger wire now please |
|
Silver Member Username: Sleste8Shelbyville, MI United States Post Number: 215 Registered: Mar-10 | that amp calls for a 300amp fuse also. if im not mistaken...how long has it ben hooked up on 4 awg? |
|
Gold Member Username: BonhamdTraverse City, MI Post Number: 2216 Registered: Nov-07 | i dont know if he is running 4 guage....but typically, the fuse you use for 4 guage is 125A always remember to fuse for the wire size.....not the amp www.bcae1.com scroll down to #14 on the site give the whole site a read when you have a chance its a great site |
|
Silver Member Username: JbpittPittsburgh, Pa. Usa Post Number: 439 Registered: Jul-09 | If he is running 4gauge,wouldnt that be ok since hes running the amp at 2ohms? Idk,im just asking cause i may need to change my wire then.lol |
|
Silver Member Username: Gcs8Atlanta, Ga Post Number: 594 Registered: Sep-09 | that amp lives in 2 ohm land ever senths i got it, i all ways fuse for my wire not my system, no fires for me. was runing a 125 amp fuse with it senths xmass just fine, voltage drop in back under load only drops down to ~12.9-13.1 and only on a 50Hz tone, on music i have never seen it drop below 13.4. ect ect. however i am getting a 50' spool of shok 1/0 for my bday next month and i plain on running one run for pos and neg. but this amp will probly never see 1 ohm even when all electrical has been up graded. |
|
Platinum Member Username: Nd4spd18Philadelphia, PA Post Number: 11144 Registered: Jul-06 | Even at 2 ohm 4 awg is NOT enough for that amp... even if it doesn't blow the fuse right away, you are losing efficiency from that wire |
|
Silver Member Username: Gcs8Atlanta, Ga Post Number: 598 Registered: Sep-09 | i know thats why i am getting 1/0 in July, as i am a brokeass i haft to work with what i got. i wasn't urning it at full tilt before i had it at -3db or so and set the amp at 90% and don't go past 75% on the HU, ect i only needed to get around 800 watts to my previous subs. all things in due time. |
|
Diamond Member Username: WingmanaliveWww.stainles... .ecrater.com Post Number: 22933 Registered: Jun-06 | When needed I can give you a steal on some good 1/0ga CCA Shok wire. |
|
Silver Member Username: Gcs8Atlanta, Ga Post Number: 599 Registered: Sep-09 | we talking 50' spools? i also will need new fuse holders and good ring terminals, might be for getting something not sure. |
