Question about Kenwood KAC-7202 Car Audio Amplifier
Just currently bought this amp used, was told "works" but upon recieving it, it obviously doesn't.
Amp powers up best I can tell, light comes on strong and steady, cooling fan turns fast.....yet no output.
Have tried 2 different signal sources and still nothing. RCA feed lines are new and functional.....sub cabinet is new and functional.
Have Kenwood KDC 10-22 reciever/cd , doesn't seem to have RCA output as well. Any suggestions?
Hey cursedknight, I know this is an old post but let me know if you
got your KAC-7202 amp fixed cause I can help you. I have the same amp with some output transistor problems or power supply transistor problems. You can remove the bad transistors that are reading bad and power up the amp and it will work, not all amps will but some. I have an Insignia amp I am workin on and found one bad power mosfet transistor there are 3 per side. I took all 3
on the side that I found the bad one on and powered it up and it worked, but with half the power. Try doing that, if you find one bad
take tall them out on the side you found the bad one on and put power to it. Same thing goes for output transistors. Go to youtube
and type in car amp repair and there are 9 videos of a guy showing you some really good repair tips and also go to www.bcae1.com this guy has all the info and a dvd rom you can buy. On his site there is alot that will help. Good luck

If possible return the amp to the seller for a refund (before you tamper with it).
If that's not possible, the amp will need to be repaired. Do you want to try to repair it yourself?
For the head unit, you need to check the shield ground first. The following page will show you how to perform the test.

Let me know if you have any other questions.
