As said in the topic, i'm having issues with my sound system. But before i describe anything i'll tell ya aobut my setup:
JBL Head Unit
Stock front speakers running off the HU
1x JVC Amp 2 channel, 250RMS per channel (call it AMP1)
1x JVC Amp 4 channel, 100RMS per channel (call it AMP2)
2x 6" speakers running off AMP2, 1 channel each
1x Pioneer sub 800MAX 400RMS running off AMP1, both channels bridged
Now, those figures may not be exact, but i don't think wattage has anything to do with this.
The problem:
I usually pump my speakers pretty hard, but i'm not stupid. I'll have it at a volume of 25. To compare, if i throw it up on 33-35 i'll start getting clipping.
After awhile, and this SEEMS totally random, the whole sound system will just shut down. That is to say, the amps will turn off and everything but my HU and the stocks plugged into it will be dead. Now i haven't had much of a chance to look into exactly what happens when the system 'randomly' dies because i've never been in a position to pull over. But one time i managed to open the boot when they were dead and noticed that the amps were TOTALLY dead. That is to say, no protection light, no nothing.
Funny thing is, they can come back on on 30 minutes, just out of the blue. Or they won't come back on for days.
So you think, its obviously got to do with the power from the battery to the amps. And that'd be a good assumption as both amps go off at the exact same time and the only things they have in common is the positive power running from the battery and then spliting into 2 wires in the boot. Problem is, i'm dead stumped as to why its doing it. I've got some phat assed 2 guage wire going from the battery, to a fuse (can't remember the rating of it, but its massive :P), and then to the boot. Now admittedly, the connections into the fuse tube and the splitter in the boot are pretty shody, as 2 guage is ****in huge and everything has holes for 4 guage. In other words, the connections are pretty crammed full of copper.
I guess i should really just rip it out, buy 4 guage and do it all properly, but every time the system has died and i've checked the connections and they've looked fine. So i thought i'd just put it to you guys and see if theres anything obvious i'm missing.
