Are there any guides online or can anyone explain the best way to hooking up multiple amplifers into a..?

Question

car audio system?

Answer 1

you need to run a power cable 4 gage or so from the battery

to a power distribution block .  then run 8 Gage power wire from the block to the amps .then run ground wires and RCA cables etc. there maybe guides on-line also.  if u are not sure how to do this talk to a tech at a stereo shop or just get them to do it for you . if done wrong u could cause a short circuit or a fire ..

Answer 3

You must supply power from your battery to every amplifier in your system. You could run a separate power wire to each amplifier, but a power distribution block will give you a cleaner installation with less potential for noise problems.

Ground your amplifiers in reverse fashion — one 10-gauge and two 8-gauge ground cables run from the three amplifiers to a grounding block. A 4-gauge ground cable connects the grounding block to your vehicle's chassis. You'll need a relay on the turn-on lead to protect your receiver. A relay connected to the power antenna lead draws little current from the receiver, but supplies enough power to turn on all your amps simultaneously.

You can use RCA patch cables to send signal from your receiver to your amplifiers. A receiver with 3 sets of preamp outputs can provide signal for your front, rear, and subwoofer amps. If your receiver has only one set of preamp outputs, you'll have to use a Y-adapter to provide signal to a multi-amp set, or look for amps with built-in preamp outputs (allowing you to daisy chain the signal from one amp to the next).

Let's say that you want to install a 200-watt mono subwoofer amp, a 75W x 4 amp for your door and rear deck speakers, and a 30W x 2 amp for your dash speakers — 560 watts of total system power. Run a single 4-gauge power wire from your battery to a 3-way (or 4-way) distribution block next to your amps. From the block, 8-gauge cables supply power to your subwoofer and multi-channel amplifiers, while a 10-gauge wire feeds the 30 x 2.
