Hi everyone,
I have an issue with my system that I'm trying to troubleshoot. I suspect that the technician at my shop either is not good at troubleshooting or is trying to avoid a lengthy repair.
My system originally consisted of an upgraded head unit, 4-channel amp, and new speakers. After a month I added a sub, mono amp, and 2 farad cap (cap has a volt meter but no remote lead). Each amp and the cap has it's own ground. +12 volts appears to go as follows:
* from the battery
* through a 100-amp fuse (not blown)
* to the 4-channel amp
* to the cap
* to the mono amp
Recently I've had both amps cut off intermittently (with increasing frequency); when they cut off the display on the cap goes blank. At first I suspected a bad cap, but (with the way it's wired) that does not seem likely. The technician noted my battery was bad and did not check any further. I replaced the battery and the problem persists. I also verified that the alternator is working well.
When the amps are running they sound great. The head unit (Kenwood 6960) works fine. The car runs perfectly. The car is a 2006 Odyssey. The 4-channel amp (XR4S) is under the left second-row seat and the mono amp (XR1S) and cap are under the right second-row seat.
It seems that, as the amplifiers do not turn on at all, I have a problem with either the power (+12 volts) or remote wiring. The fact that the cap display is off seems to indicate that power is being interrupted. And, the fact that neither amplifier comes on seems to indicate that the problem is somewhere between the battery and 4-channel amp.
Since I've had this system for a while and this problem started recently, it seems that the installer screwed up somehow and a break in the power cable developed. I'm thinking I should ask the shop to rewire the power cables (to correct the supply interruption and to fix the cap wiring) but wanted to make sure I thought this issue through carefully before I start making demands.
Does anyone have suggestions on what else could be wrong besides the power connections?
