So I'm driving for 30min, sub is working fine. Park for about 30min, turn radio on....no bass. I changed source on the radio, sub makes a sound but stops working. I pulled the sub to check tinsel leads (one had cut off a while back) and everything is fine and still connected. What could it be?

 

test voice coils with a multi meter?

 

Loose wiring, amp shorting out, fuse, HU output issue, bad ground, loose/bad remote wire, it could be a number of things you're going to have to trouble shoot a bit in order to really figure it out. Double and triple check your wiring.

 

Haha, it's Dons wiring...not mine. I guess I will be paying Don a visit soon.

 

Wiring is wiring, you can still check it

 

I know....I guess I will pull the dash tonight and check the RCAs. The weirdest part is, it was working....then just stopped. I'm praying nothing happened to the amp.

 

well does the amp power up and the sub not work? or the whole thing not working?

do you have a second amp, if so, is that one working?

 

Amp works...it's a 5 channel. Only sub doesn't work.

 

Ah so either the sub is toast (voice coil) sub channel is toast, or wiring is fubar'ed somewhere.

Hook the sub up to any one of the other channels of the amp and see if it works or remove the sub from the box and try it directly on the sub channel + one of the other channels to verify operation of the sub.

 

^what he said

 

Hmm so feed a LP of 80Hz to his front stage? Sounds like a BAD idea. FTL.

 

For 5 seconds to test it leaving all settings the way they are, it's going to be no problem. He will be able to tell if the sub is working or not

 

yea or he could take a pos speaker and touch the sub terminal on the amp.

 

Wiring was never touched so I can't say wiring. I'm not touching anything, Don will be seeing my car soon.

 

Well of course you know better than I do. Unfortunately I dont do that with others equipment.

 

Never said I do... but how could it hurt?

Regardless he's comin to you soon

 

When you finally put your stuff into your car, then lemme play with it, K?

 

Lol what are you gonna do to it?

 

I felt like a moron the other week when I finally installed my equipment. First it didn't work because I forgot to bolt the ground... Tilley was at me.

Later that night, it stopped working and I checked everything with the amp. Power light was on and all.

So 2 days later I drag out my old amp and half working sub to diagnose...
Then I realize the (-) speaker wire into the box came out

 

that will do it

 

i can't really say to much, because i noticed my subs weren't working the other day and i almost dissasembled everything and through away all the crap, i was pissed. it turnes out the wires inside the box came loose.

 

Ahh the saga of my car....sub started working after I pulled it out and reconnected it....strange.
I guess Nismo was right.
