alright, i have 8 guage wire connecting the battery to the amp. 14 guage wire connecting my speakers to the amp. i have 2 kenwood 12's rated at 800 watts peak. the amp is a Sony Xplod 1800 watt Class D amp. i have size 30 fuses in the battery wire and the amp. my amp will no longer turn on because the lights showing overcurrent, offset, and thermal come on. the amp is a 4-channel MPA-6000. help.... please.
a: what's the RMS rating of the amp? 1800 watts RMS should have 0 gauge wire. 8 isn't NEARLY enough. I doubt your alternator would cope with that much power either.
b: it's a sony. that's part of the problem. they fail. a lot.
c: how are the subs wired to teh amp, and what is the load presented?
this sounds like the subs are presenting too low of a load, you have a short somewhere, or the amp just went tits-up.
umm... i have some 4 guage wire that i havent installed into the car yet... soon enough. the two subs are wired together then connected with one 12 guage wire to the amp. i just replaced the fuses this morning, no change. A: i do not know what the RMS is. i will find out when i get home. C: what do you mean by load?
ok this is a 4 channel amp? with two subs? how many coils does each sub have? what is each coil's impedance? (4 ohms?) how are you running the two subs on a 4 ch. amp? amp bridged? just one sub per channel with two channels not used?
RMS- the wattage that the amp puts out constantly.
If a amps is rated @ 1800 watts then it's the peak of wattage that the amp could produce but you'll never get that. If your amp is a sony then most likely the RMS is nearly around 600-900 watts and divide that by how many channels you have and you'll get the RMS wattage of each channel.
