I recently put a 600 watt Pyramid amp & 2 300 watt Pyramid subs in my Xterra. I installed them, along with a Jensen head unit, myself. The system worked fine for a couple of weeks, but now no sound comes from the subs & the power light on the amp barely comes on when the head unit is turned on ( then it fades totally out). I swapped out the amp with one I had laying around, still nothing out of the subs, however the power light stayed lit on this one. I also used new wire to connect to the low out and this did not make any difference. Any suggestions would be greatly appreciated. I have put systems in other vehicles & not had any problems, but this one's got me stumped. Thanks in advance.

i would think just because of the light being very dim that your power wire or ground is either not getting a good connection or is shorting out against something. you could test to see with a ohm/volt multimeter to see what power you are getting to the amp and coming out of the amp if any. and also check the speakers ohmage to see if they are working since a second amp didnt give you anything.

Agreed, most problems that are difficult to troubleshoot end up being poorly grounded systems. Keep us posted on what you have/ have not checked, and we will help any way we can.

I finally got around to checking the wiring & found it to be the power wire. Apparently there was a problem at the fuse holder, as I replaced this part with one from a sytem awaiting install in another vehicle. Thanks for the suggestions.
