Multiple Amplifer Set Up

[IRLRs200]

Just a quick question for the audio guru's, Thinking of re-wiring my amplifiers. At the moment i have 1 power cabling per amp coming from the Battery and 1 seperate grounding point per amp, and a shared remote amp wire. can i use just one power cable for 2 amps and them just branch off the power in the boot with a distributor block. can i do the same with the grounding wires? Have the earth cable from each amp going onto into a distributor block then to one grounding point on the chassis?

Also I've had a power cap stilling in the shed for about a year, are the worth using? If so are they easy to hook up.

You should have one cable with suitable fuse coming from the Battery and split using a fused distribution block.

The 2 grounds should be fixed to one point / same point on the chassis.

a single remote wire split to feed the two amps is fine as it carries very little in the way of power.

As for a power cap... there is always a mass debate ( :P ) when it comes to these. i have tried with and without and to be honest there is never much differnce. would recommend getting a biger batter but if its just sittin around then you can try with and with out and make up your own mind!!

Yes you can do the same mate,

You can buy unfused distribution blokes for this very purpose. i've got one in mine.

So i'll just need one fuse just before the Battery like i have on the 2 power cables or should i fuse anywhere else since im running the 2 amps off the one power cable?

My advice would be to run 1 large cable from the Battery with an inline

fuse in the engine bay like this (or similar) .

Then run through to the boot to a seperate fused

distribution block, then 2 power cables to your amps.

You can then run 2 earth cables from the 2 amps to a

suitable singleEarth Grounding point.

The remote turn on wire carries just a trigger current,

so is fine for several amps.

With regards to power caps.. opinions do differ, but I am running one in mine

and am getting better results than without it, but its a bit of suck-it-and-see,

and results do differ depending on the quality of the power cap in question +

it's capacity. (capacitance)

Hope this helps

As Wozza says, run a large cable 0AWG (fuesed) into the boot then use a fused dizzy block. Although i have always run seperate grounding points.

Power caps... hmmmmmm............

Always ground from the same place, at less than 0.5m to your amps.

Power Caps... We sell them.. Hell no do we! I have LOADS in stock, we simply don't sell them because its against what we preach...

Power Caps.. not worth it, run a bigger power cable or upgrade your Battery :winky:
