protection light!?

[morotorium]

My install has taken a crap on me; before I get into details, here are the major components:

93 Jeep Wrangler

JVC KD-AVX11 HU

Boss CH900 amp (1600 watt bridge 800 watt x2)

2 x 800watt max 400 watt roaming subs (don't ask the brand.. lol)

For some reason, my amp started going into protection mode. At first if I kept the levels down, it would be fine until I turned them up past a certain point. Now it just goes to protection; I even have the RCA cables and speakers disconnected to try and isolate the problem. The rest of the system works fine, since I am running straight of HU.

1. Re-grounded amp to fresh ground point in pan underneath rear seat

2. Hooked up SPL 4 farad cap (I know i know, it was free and collecting dust in my attic..)

3. Re-grounded battery and engine with 1/0

Nothing. My cap is a fairly constant 14.1 (drops to bout 13.9 on car start) but my amp with just power wire, ground , and remote wire just goes to protection now. I've also tried my previous amp which is a Boss REV635, which is what I thought was the problem and purchased the new CH900 for, to no avail...

Ideas?

Boss.

Time for new amp and subs.

Buy quality, buy once.

Call Boss. See what they can tell you. If they tell you it's shot, kindly ask for a new one (or better, compensation.)

I threw in my old REV635 and once again I can run it with gain and levels up to a certain point..

If I had the money I would gladly go out and buy new amp and subs (providing I could still fit them in the custom enclosure). That, and it's a soft top jeep wrangler.

Any other ideas on what might be causing this issue?

Thats why I tried with RCAs and speakers not connected...
