jbl gto7001 amplifier turns on. no output to channels

[bartles]

Having a problem with my gto7001. Determined that the amp gets power but it wont output to my subs.

And i know its not wiring or deck etc. Substituted a working amp which did the job.

Does anyone in here have experience with amp repair? What could i be looking at and is it fixable?

Any knowledge beyond mine would be appreciated //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Hopefully theres some use to you in there somewhere! Nothing looks like its been burnt or anything.

I swapped my head unit and battery and after my subs wouldnt work.

Ive ruled out everything else. And as i said it powers on but doesnt output a thing.

the first think i would do is get a 3.5 jack to male rca and play your phone throw the amps .

plug the rcas into the amp.

that will eliminate h/u , rca from h/u to amp.

make sure your ground and power wires are right.

No need i had my buddies amp n subs out today n plug n played it all.

His amp n sub worked on my wires n h/u and my subs worked on his amp. So i know its an amp issue
