Little help with wiring
Alright so i'm not quite sure how to wire everything in my car. I'm a little unsure of the wiring I will need to hook up a 4ch amp, a monoblock amp, and a farad cap. I was looking at going 4 guage but i'm not sure what the inline fuse size should be, and how to wire from the cap to the two amps. Also if I have the two amps and the cap where do I run the remote wire. I've done some reading but am still unsure and any help or diagrams would be very helpfull and much appreciated.

fuse size would be as large as all the fuses on the amps combined
remote wire would run along with the RCA's from the head unit
cap... hook that up later if you realy need it, its a crutch more then anything else

I thought the inline fuse had to do with the maximum amps your alternator would output. And about the remote wire, what I meant was how to wire the remote wire using two amps. Would I run the remote wire from each amp and splice them together and then into the remote wire on the deck?

I take back what I said earlier about the fuse size based on the amount the amplifiers will use. My new train of thought is base it on the size of the power wire going to the amps. You don't want the current to exceed that or the wire could melt. Just like in your home you have 15A circuit breakers for most electrical outlets for a reason, so you don't melt the wires in the wall and burn the house down.
The wire going from the alternator to the battery is very short and should be at least a 4awg size to handle the amperage the alternator puts out. No need for a fuse on that as far as I can tell.
Now the remote wire can be spliced together at the first amp it goes to so it can be run to the next amp. If you have more then two amps you might want to use a remote turn on relay to avoid drawing too much voltage from the head unit and wrecking that. I have three amps and no problems after more then two years of use. So I say you might want to but don't have to.

circuit breaker of 135 A rating would be nice

I have a 100 A circuit breaker at the battery for the power wire going to the amps. Can cut the power easily if I'm working with that wire.
