Alright guys, i have an Alpine head unit with 2 pre amp outputs. I have a 4 channel amp already in my car, hooked up, working and everything for my 4 speakers. So the 4 channel amp is all done with.

I have a 2 channel amp to power my subs, and distribution block, and a cap. How would u guys set the new stuff that i have up, and keep my old stuff there to? Just how would i add it in for the easiest cheapest install? (power wire to distribution block then split to the cap an amp? or what?)

Plus, for my 4 channel amp, i have a 60amp fuse up by the battery, and my 2 channel amp ill do the same. My 2 channel amp has 4X 25 amp fuses on it. Ill have the 60 amp fuse up by the battery, what size should i put in the distribution block?

Thanks a lot guys in advance.

60 amp fuse up front won't be enough. You need a fuse the same rating as all of the fuses on your amps added together.

Theres 4 X 25amp fuses on my 2 channel amp. So i would need to put a single 100amp fuse up by the battery? Cuz the amp kit came with a 60 amp fuse.

Also, how woud i set the system up and wat size fuses would go in the distribution block?

What are the fuses in your 4 channel amp? Assuming it's 60a, which it mnay not be, you would need 160A fuse up front. Then in each distrobution block, you would need a fuse equal or slightly higher then the fuses on the amp. So for the 2 channel amp you'd need a 100a fuse, and the 4 channel amp you'd need a fuse the size of all of it's fuses added together.

what size power wire do you have run? You will need at least 4 gauge for this.

Alright, im going to try to explain this the best i can. My 4 channel amp is completely seperate then the add ons of my system im going to do. At least thats what i was assuming i would do. The 4 channel amp has 2 25amp fuses on it, and is ran with 8 gauge wire whre it has a 60 amp fuse at the battery.

The 2 channel amp, for my subs, has 4 X 25 amp fuses. i am going to run 4 gauge wire like u said. My amp kit came with a fuse holder for up by the battery with a 60 amp fuse, but thats to small i guess.

My first problem is, how am i going to wire the amp and cap with the distribution block, if u can help me out there, i should get the rest easier. Would i run the main power wire 4 gauge to the distribution block, then branch it off to the amp and cap?

like it says in the FAQ section.. which is why I wrote it :P
get a 3 way electronic crossover (Coustic XM-3, Audiocontrol 4XS, or similar) and use that to control all 6 amplifier channels as your XO.
that allows you to run 4 channels out of the ehad unit to a fully XO'ed and controlled 6 amplifier channels.

for power, you use a 1-to-4 d-block, and split two lines to the 4 channel amp as needed, and one to the 2 channel amp.
put the capacitor on the sub amplifier alone, in parallel, right next to the amp physically to keep the wiring as short as possible.
use a fused d-block to protect each amp line, ground the amps to sanded bare metal close to the amps.

Wait, so you are running two power wires? If so, then you don't need to distribute anything. You simply run the 4 gauge wire into the + on the cap, then from the + on the cap to the power on the amp. Then ground the amp and cap. You will need an ANL fuse holder for a 100a fuse like this one : http://knukonceptz.com/productDetail.cfm?prodID=FH-20

Thanks a lot every1 for your help. Yes i am running two power lines, and i ordered a 100Amp circuit breaker instead of the anl fuse.
