Kenwood KAC-9103D Is not powering on

[GunplayBen]

So basically, I have looked at the other Kenwood KAC-9103D thread, but it was no help. If I can get a little more descriptive info on what was unsoldered. Because same thing happened too me, and I know it is probably a really shitty and stupid mistake, but my grounding came unwired some how and I went back into my trunck to check something, and when I saw it, I decided to put it back in normally, and accedently slipped with my hand, and hit the power cable. And the last thing that happened was a spark and poping sound. My fuses are 100% okay. My wiring works, because we threw my friends 1000w xplod in their, and it worked, then we threw teh Kenwood KAC-9103D into his wiring, and nothing again.

So the wiring is good in both cars, and yes my wiring is okay in my car, because I have run teh amp before and it was fine. If someone could provide me with a circuit map, or something, so I can see labels and things, I can probably figure out this problem myself, but any help would be helpful.

And yes I have googled and looked around, and cant find anything remotely helpful.

Sorry too be such a scrub but it would be very grateful for any help.

It's common for Kenwood and Pioneer amps to burn traces when this happens (if I understand what happened).

You'd need to have the amp powered up and measure voltage on several points to determine the problem. Can you do this?

 

[GunplayBen]

If you tell me what I need, I can most likely do this. Im not completly incompetant. Hah.

I already took teh amp apart just too see how it functions, and see if I could see that unsoldered part, but to my luck, no success.

So yes, if your willing to help me man, I can do it.

You need to have all transistors tightly clamped to the heatsink and have a 10 amp fuse in the B+ line feeding the amp.

Measure the DC voltage on all 3 legs of Q12 and Q20.

Place the black meter probe on the amplifier's ground terminal. Place the red meter probe on the point where you need to measure the voltage.

Okay, I will try that, but what do I use to measure the voltage.

 

[Perry Babin]

A multimeter.

 

[GunplayBen]

Aight, thank you man. I will get back too you when I do that.

 

[GunplayBen]

I really appreciate the help man, and takin your time to help. But when I went to get a multimeter, the guy at teh shop was like "Let me take a look at it." Knowticed something came unsoldered like we suspected. And it took 2min to fix.

So thank you for taking your time out to help. :3
