Amp repair shops in Phx AZ? - Page 2

It may not be difficult to repair. The symptoms sound like power supply problems. These amps have problems with the busbars. The connections break and cause various problems.

If you can power it up and are willing to check voltage on various points, I'll tell you what to check.

Unfortunately I do not have a 12 power supply just lying around, and it would be difficult to use my car's power supply.

What is a busbar? Is that anything that I can check through visual inspection, or with a DMM without the amp powered up?

The busbars are the metal jumpers. It's not likely that you'll be able to see any of the bad connections. It would also be difficult to find them with a meter.

You'd need to power up the amp and check voltage at several points. When you found that voltage was absent at a point where you should have voltage, you'd trace the problem back until you found the break.

If you don't have the ability to work on it easily, it's probably best that you pay to have it repaired.

If you don't know of a good repair shop in your area, call the local car audio shops to see who they use for repairs. If several shops recommend the same repair shop, they probably do good work.

Awesome, thanks, I will check that out!

I have also heard that Soudwerks in Scottsdale might be OK.
