i also took the sub out of the box to see if any wiring was messed up from being in the bed, but it was all good.

 

sounds like your amp is screwed, or have a bad connection somewhere

 

When the power wire came out it may have arced off on the amp. If so then it may have fried something inside of the amp.

 

That was what I was thinking. I have seen it happen before, actually I didit myself once. Learned the hardway to pull the fuse out before removing any wires.

 

yea thats probably what happend..the sound might be the altinator whine...hopefully the power didnt touch the ground lol then its time to get a new amp.if not you should beable to fix it with maybe some mosfets and a saudoring gun.

 

with maybe some mosfets and a soldering gun.

Fixed

My guess is that the speaker outputs shorted out on each other and something got messed up inside the amp. No offense but Crunch isn't the highest quality amplifier out there. This leads me to believe that something stupid like this could happen with such a budget amp.

Again, don't take offense that I mentioned it's a budget amp, it's just something I take into consideration.

 

im gonna try to run my sub off of my friends amp today and if it works like its supposed to, then i know its got to be something with the amp. the amp is a crunch 1400 2 channel for only $100 so it isnt so bad to replace

 

thats a nice amp for pretty cheep..and true if it works then get a new amp lol

 

ok so my sub works perfectly on my friends amp. so what would be a good amp for a cvx 12'' 4 ohm with 750 rms?

 

800a2 punch series rockfordphosgate baby!!!!

 

i'd put rf on the same quality level as hifonics these days

 

The 800a2 would definitely not fall under "these days". That's old school goodness right there.

 

thank you danssoslow that amp is amazing my dad has had his since he was 15..hes 32 now.and that thing still out does any ones around here.

 

so i bought a new amp...hooked it up...and it does the same shit. my sub still vibrates when the volume is on 0 and makes a high pitched sound. when i switch the crossover switch to lp/lf??? (or something like that) the high pitch stops but still vibrates and makes a low pitch hum when the volume is off.

i guess ill bring it to a local car audio place?
