Multiple amps on dual runs


Recommended Posts

So I have a single run of 3/0 but will be adding a second run soon to feed my taramps 8k. I also have to power a pair of pioneer 2 channels also, one for tweeters and 1 for mids. They are about 500rms each. Can I just run both the pioneers off only a single run that also feeds the 8k ? I will be doing a dual 3/0 to single 2/0 at the 8k when I run second run.Will it make a difference or do I need to go full out busbar which I don't really have room for at all. Was thinking of using one of these on power and one on ground ( ground only because I'm popping through cab and hooking to my frame and don't wanna run 3 wires through my cab. I have a 3/0 gromet that I'm gonna use). Going to fuse with a 450a on each run.

Feed all your front to rear runs to a buss bar style distribution block, then feed all your amps from that bar

that's what I figured I would have to do but I don't honestly have the room to run a full busbar but them small blocks I can hide them somewhere

You plan on just shoving the 4g I to the 2/0 output?

 

There is a perfect solution from knukoncepts called the 'KonFused" block

 

Go to site look at all the pics of it and read about it

 

It's way more than it looks like. 26 possible configuration

That does look nice, but look at the pic I added above, 4 bolts, figured 1 for 3/0 in, one for 3/0 out, and 2 for 4ga (one each amp) and it's only $15 , even though I'd need two. Will look into the block u posted too looks nice.

I guess I'm more worried about more draw off of one run of 3/0 than the other. Getting wires to everything is the easy part, a bus bar would eliminate that but like I said I don't honestly have room, I'm actually trying to figure out where I'm gonna mount 3 amps lol.
