All,
After searching threads and much needed feedback from forum members I believe my amp under the front seat may be the problem with my radio volume, or lack there of, as everything else on the radio/CD player work just no sound or volume bars. I do not see any light on the amp when the vehicle is started so... Few quick questions...
Anyone ever swapped one out?
How long should it take and is it difficult?
Should it be just an unplug old one and plug up new one?
Any ideas where I can find a good used one, online, as there are very few places to go and pick parts around me?

Much thanks!!

 

Assuming you have the HK Logic7 system, eBay is the best place to find one. There's on there now for $200 which is a great price.

I've swapped mine out and the most difficult part is freeing the clips on the various connections. The 4 screws/nuts are pretty easy using a small enough tool to access from the front and then the rear - just move the seat.
