Hooking Up two amps and need some help.
Saturday, January 21, 2006 9:18 AM
Ok the search that I came up with is hooking up two amps to subs.
I have two amps. One is going to be hooked ONLY to the subs.
The other I wanted hooked up ONLY to the mids and highs.
I have ran the wire for one amp already.
Im just not sure on how to get power and everything to the second one. Any help?

Thanks.

run main power wire into a cap, from that into to a distribution block, the block will seperate power wires into each amp, ground cap to car and ground each amp to car also (doesnt have to be same grounding point) run two sets of rca's and split the remote wire then your done. if you dont have a cap just ignore that part and do the rest. Rememeber to run power wires away from signal wires(rca's, speaker wires, and remote) good luck

use a fused distrobution block to split your wire into two.

ground both amps to the chassis.

splice your remote wire to both amps.

run two pair of RCA's from your headunit IF you have that many preouts. If not you'll need a crossover or something.

Most people that I've seen only run the sub amp power wire through the cap (after the ditribution block).


But what would I know...I dont use caps.




You can also use a non-fused distribution block for the ground. This way you only have to run one cable to the chasis. Kinda makes it look a little cleaner too IMO.

one thing not mentioned.. make sure you have the proper gauge wire need to run the power of two amps. and fuse under the hood near battery and a fused dist. block for the trunk is a safe way to run them.. and if you run a cap you should only need it on the sub amp since they regulate power in more of rapid manner than one powering mids.

hey whats up?if you have 4 gauge or bigger i would run it to a distrabution block(fused) then run 2 8 gauge wires from that, 1 to each amp.you can split off the remote turn on,no need to run another wire. make sure that you use the same size ground wire(8 gauge) as the power wire,and ground the amps at the same spot.(to prevent any ground loops).if you dont have 4 gauge already ran you can just run another 8 gauge wire (fused at the batt.)following the same path as your orig. power wire.also make sure you ran all power wires on 1 side of the car and the signal wire/cables down the other side.as far as your rca cables hook your sub amp to your sub preout,and the other amp to the front/rear .i hope this helps.did you get your interior done,i havent seen anymore posts on that.

I didn't bother with a distribution block. I ran a fused 4ga power wire from battery to cap in trunk, and then from the cap I ran 2 seperate 8ga power wires to each amp. I've had no problem what so ever and I've had that set up for over 2 years nows.

you need to fuse those two 8awg wires. if one of them shorts out somehow, your car will go POOF

Is it okay to fuse BEFORE the distribution block? I had one amp but am adding another, and I'd like to just connect the old (fused) wire to the distro and to two amps.

Yes? No?

anytime you go from a large wire to a smaller wire. YOU MUST ADD A FUSE.

If you go from a large wire, to two small wires, you must add two fuses. simple simple

the fuse should be as close to the power source as possible, so it is a good idea to have it before the block as close to the start of power supply cable (under hood?)

Ok. I'm running a fused 4ga power wire from my battery to a cap in the trunk. From there i split into 2 8ga power wires that run to my 2 amps. You say I should fuse the 2 8ga wires. Should I run 1 4ga fused wire from the cap to a distribution block which will split into the 2 8ga wires I need for the amps or should I run the 4ga wire from the cap to the distirbution block which willl split into 2 8ga and then fused both 8ga wires before they get to the amp? I hope you can understand what i'm trying to ask here. thanx.

after the cap. wherever you currently are going from 4awg to 8awg..fuse it.

Sorry, you did not understand what I was asking. Should I put a fuse(s) after the cap, before the distribution block, or after the distribution block, before the amps?

um...you put the fuse INSIDE the distrobution block homie..it's called a fused block for a reason.

Um yes, that's what they call them but they DO have regular distribution block too. I asked because i have a spare distribution block as well as s couple of spare inline fuses. So either way will work i'm guessing?

what the hell is a fused wire??? and a distribution block??? and a fused block??? please help i have the same setup im trying to install as well

a fused wire = a wire with a fuse....a distribution block is a block that separates one large wire into a number of smaller wires, and a fused block...i think its a block that has the fuses inside the block for every of the wires coming out, correct me if im wrong though

ok whats wrong with this setup???

4 gauge from
Battery>Cap>take 2 4gauge from the cap to both amps(one for each)??

so the cap will have one 4gauge going in (from batt) and 2 4 gauge coming out to both amps...
will this blow something???
i see people talk alot of 8 gauge going to amps...whats wrong with 4 gauge going to amps?????


ALSO:
can i use a non fused dist block to put both ground from amps and ground from cap into one and only come out with one ground???

or should i just ground all three together somewhere???

Your setup is exactly the same as mine except I have 8ga running from the cap to the 2 amps instead of 4ga. Most amps cannot accept a 4ga wire which is why alot of people run 8ga to the amps. I wouldn't run the grounds from the amps and the ground from the cap to a distribution block for grounding, I would ground all 3 items seperately to different grounding points.

use the proper size wire for your amplifiers. if your amps require 4awg, USE 4 AWG!

And yes, using a ground block is just fine for your cap and amp. then only time it's really not recommended is if you have any sort of audio processors (eq, crossovers, etc..etc). you want to ground those seperatly because you don't want any noise introduced by the amplifiers ground.
