sub probs
 

hey
well my sub was workin fine all this time...got a new box and sub and its been runnin for a month or more now with my old wiring and amp...
sounded great...
but now its not poundin as hard and it doesnt work thruough the whoel song.
like it works for a but then no bass then back on again then no bass...
wats going on???????

miss having bass...havent turned on my sub for a while now...:(

the amp is overheating and going into thermal protection. with the heat we have now i'm not surprised. mine does it too

^ My thoughts as well.......although can't hurt to double check the amp wiring...

also clear any crap away from the amp give it better odds of cooling...

what is the impedance of your subwoofers? Are they dual voice coils? what amplifier are you running, a mono amp or is it a stereo amp that is bridged? it could either be the impedance (ohms) is wired too low for the amp or there could be a short in a subwoofer somewhere.

ya thats a good point about the over heating..
i used to have the amp on the top of my box but now i put it behind the box so maybe thats it? it worked fine like that for over a month tho..

its a bridgable amp and the sub is svc
the impedance did change alot though from my old sub to this one..

either way it worked so well before...im hopin its the heat..gonna remove the trunk cover and put the amp back on top and see how that works...
checked all the wiring and fuses...the amp is gettin power...jus the sub isnt getting power for some reason...its worring me alot..
gonna try to open up the box this weekend and see how things are doin inside...

wire a computer fan and bolt it next to your fan. power it through your remote wire.

you should keep the amp mounted vertically for better heat transfer

i've tried it i got a humming out of my sub

im hopin its something stupid as over heatin and not a real problem thats gonna be costly...that would suck ass...

could it be that my amp is workin harder now with the new sub that it is over heatin?

check your grounds.

this happened to me as well just yesterday. my sub was pounding so freaking hard that the male connectors inside the box came out. I thought it was the amp so i was screwing around with the amp and increased the gain and bass boost on my amp..

I suggest:

1. When it is really hot open the rear seat so there is more air going to the amp.
2. Lower your gain a little bit (it might give more bass at a low volumer but it will sound cleaner with loud volume and not just a bunch of rattle) trust me on this
3. is you have a bass boost do the same as step 2. Its like tuning an engine, do the proper settings for your amp and you get good results. Right now my sub pounds better then ever because i fixed the settings yesterday.

Thats what i did and its better now...give it a try.

sorry double post...owned by the slow ass net at work!

stop pumping soca chutney so hard. :P

toooooo freakin hot to work on anythin...this is y i hate summer...
anyways ill check the wiring inside the box..thats the only wiring i havent checked yet...

thanx for all the help all...:beer:

he he

When the bass stops, the thermal protection mode light will illuminate if the amp is overheating (if the amp is equipped with one). If the protection light is not on, check your grounds with an ohm meter.

Hmm....maybe your amps girlfriend has gone away for a few days and its too busy crying to play your bass.

^burn!

say wat u want...u still drive a chick car...
do u have to hang ur balls on ur rear view mirror when u get in? :finger:

:beer:

try bridging your amp if its not alredy, and turn down you gain..

its alredy bridged
ill put the gain back to 0..but its been workin fine at +3 for over a month...thats what bothers me..
still havent gotten around to checkin the wiring inside the box that mite be it cuz it doesnt seem to be anythin wit amp turnin off or not gettin any power..if there was a bad ground there wouldnt be any power goin to the amp right?

wrong, if your grounds loose, it'll work sometimes, and sometimes it wont. depends on the vibration, bumps in the road etc. just check your grounds, re tighten everything, and hopefully thats all u need done.

ya but theres times when the amp light is on but the sub isnt workin...
wats that mean?

Yup.

But it beats having them in my gf's purse all the time.

:p

^^ hahaha

o so u keep urs in ur own purse then? :p

did you check the rcas on the back of the deck and on the amp, as well as the speaker leads, becasue if those are loose then that would make sense for your problem.

this happened to me as well i had a cerwin vega sub. Anyways the sub would get stuck the voice coil I would have to push the sub then it would work again. I bought a used ---- sub, got RIPPED OFF THE SUB BLEW 1 DAY AFTER but ccould of been my amp wasnt adjusted properly.

^^ ---- i hope ur not sayin my sub is about to blow...cuz i jus got this less then 2 months ago...

i didnt check the rcas coming off the deck...over looked that one i guess...thanx man
but i checked all the wires from the amp to the speakers...all thats left is the wiring inside the box...

i dont think ill have time to check anything until this summester is over...i really miss bass :(

If your amp is staying on when there is no sound coming out of the sub your best way to check if its your amp back to deck or if its the sub or conection to the sub is the following:
- grab a volt meter...doesn't have to be good one..any will do
- set it to AC
- probe your speaker outputs on the amp. If you get a reading but the sub still makes no sound than you know its the sub or wiring to the sub.

Try this...let me know what happens and I will help from there.

cool thanx man
