Wiring Up Two Amps?

[predator]

I'm just wondering how I go about wiring up the power for running two amps?

Am I am able 'daisy chain' the power wire from one to the next amp? Will that work?

So from the + of the one amp to the + of the next amp, and the same for the ground (-) ? From rough memory, that will halve the current (amps) draw available to each amp?

I assume running dedicated power wiring for each amp is ideal, but at the moment, I'm not really up for pulling apart the interior again for extra wiring. The gage of the wire already in place is already pretty hefty, about 5mm across so I don't think it could become easily overloaded?

My equipment isn't really high powered stuff and I don't crank the volume enough to go deaf, so can I get away with it for a while?

With +ve terminals, it should not really be a problem, but even though it will work i highly recommend using seperate GND cables, with the shortest path to earth.

A better way to do it is to use distribution blocks, one for +ve and the other for GND. This will also make it easier to wire up the amps, as fitting two 5mm cables into one termanal can be a prick.

Just be careful, if you are talking the actual copper is 5mm across or 4g then ok go for it, you shouldnt have problems, if the 5mm includes the outer sheath or 8g, then run a new cable, and upgrade the battery -ve cable (often overlooked) It may seem like a lot of work, but you really are a lot better off

Oh and the potential for current will be halved, volts are given, amps are taken

I can run two grounds, thats ok, as I am just grounding to the chasis in the boot. It's just the hassle of running to the battery in the engine bay on an R32.. If it was an R33, it would be no problems.

I have spade terminals crimped onto the ends of the wiring. I think I can rig in another to sit ontop of the other.

Thanks for the tip on the distribution blocks Al, might be worth investing in one of them to make it a bit easier.

just run distrobution blocks

your main cable run ie:4ga, then into distro block, then two 4-8ga to your amps

same goes for your grounds... 4-8ga form your amps into the distro block, and onto a nice metal part of the car

remember to put in a fuse for each amp, dont run both of the same one.

Is ok to run off one..

Fuse is there to protect your car electrical stuff not your amps...

Thus why you have to put in a fuse as close to the battery as possible within 30cm if i remember correctly. Fuse size to put in is same as the total amp of all the amplifiers. Amplifier all have their own internal protection function, some has fuse on them some has more advance stuff like auto cut out.
