Default Advice needed wiring a 5 channel amplifier

Whats up guys,

Any recommendations on what brand 4ga wire, speaker wires and RCAs to use to install an amp on my boat or can I get away with using a good car amp wiring kit?

properly sprayed with corrosion guard and di electric grease on the terminals, I have no problem with an amp wiring kit. I 'm sure others will disagree....

I use 16-2 shielded for speaker runs..shielding not necessary but I like it...

monster or equiv for RCA cables..

Not to hijack but this question is related. If your amp is in the CC and the battery is in the stern, would you run a hot and a ground wire from the battery or would you just run a single positive and pick up the ground from somewhere else like the terminal strip in the CC?

back to batt and same size as pos - like 4-6-8 gauge...support every 12 inches with eye hole zip tie in split loom - this is how half assed installs get done when you don't...

You can use a standard amp wiring kit, BUT make sure it is from a reputable manufacturer and is american wire gauge AWG. A lot of the cheaper amp kits will have power wire with aluminum core or will be sized by the jacket and not the actual wire. Use monster, stinger, jl, rockford fosgate, and any other reputable manufacturer and you will be fine. Stinger makes a nice marine circuit breaker too.

What about SCOSCHE MARINE brand? I just did my Alpine PDX 1.400 marine amp with it in 4 Ga. both neg. and pos. direct from the battery (as you suggested to me) I got it at a huge discount/clearance, but the regular price was like 150.00 or 200.00 for a 50 ft. bag! Is it the right or good power cable?

Scosche makes a good product and most of their stuff ( excluding the super cheap stuff ) is top notch.

while you are not required to.... you should follow ABYC guidelines for power wire and fuse size/location - mainly for safety reasons (and to reduce voltage drop at the amp)

If you have a battery switch, should the positive connection go to the battery terminal or the switch terminal? The battery switch is a BEP cluster with isolation connected to two Optima D31 batteries.

The best way to go for A/V cables is Monoprice. Their cables are very high-quality and they have terrific prices and service.

They are an Internet company. I don't know about shipping to the Bahamas.

The positive lead from the amplifier should go to a fuse, then the battery switch (so you can shut off that circuit via the battery switch)

per ABYC - The fuse should be withing 7" of the source of power(supply)


per ABYC - The negative should go to the "engine ground or its Buss"

Can't go wrong with KnuKonceptz.

Strange name but a very nice product while keeping pries relatively low.
