Help with Amp Wiring

[bzubke1]

Im getting ready to install the amps for tower speakers and subwoofer. I think i'm on the right track i"m just unsure of where to hook the power wire. The battery switch has 1 hooked to battery 1. 2 to the helm power and power wire from the engine. 1+2 is hooked to battery 2. I confirmed in the manual it is supposed to be this way. I'm confused. Any advise?

Get your power from the dist. block from battery 2, as well as the ground. Bat 1 and two should be grounded together, but I think it is common practice to run the distro + and - from batt 2

The "Where" wire needs to go to the "C" post of the switch. This keeps the entire audio system sharing the same power source.

The main B+ to engine and helm BUSS needs to be hooked to the "C" post also.

BATT-2 needs to be hooked to the "2" post.

The loads will draw from what ever battery you have the switch turned to.

Brandon,
All grounds are common including the dual batteries, helm ground buss, engine block and all audio electronics grounds.
Perko, Blue Sea or other standard dual battery switch:
Switch terminal #1 goes to battery #1.
Switch terminal #2 goes to battery #2.
Switch common/output post connects to the alternator/starter feed, the helm supply buss via a breaker and all audio electronics via a master breaker/fuse and distribution. You can stack three terminal lugs on this single common/output post.
Nothing besides the dual battery switch connects directly to the battery(s) positives. The only exception would be a bilge pump/float switch if applicable and the HU memory as optional.
The above is the only acceptable way.
Note, if we are adding an ACR/VSR this scheme would change substantially.
Btw, you can get a comprehensive schematic from Odin.

Below is the diagram of how it is hooked up. I knew the power from the distribution block needed to go to the common lug. I guess I just don't understand why it comes wired this way from the factory and it makes me hesitant to change it. The boat has a pro mariner prosport12 battery charger, where should I have the switch when I am charging the batteries?

[MLA]

If your charger is a dual-bank, the switch should be off when charging. This isolates the 2 battery banks so the batteries can be conditioned independently.

Thanks got the batteries all charged up now.

Both amps require 4 gauge power wire, what gauge wire should I use from the distribution block to the battery?

Speaking of distribution blocks. I need to purchase one but I have no idea what I need. I did some eBay and amazon searches and theres all different kinds. I don't want to buy the wrong one.

What info do you guys need from me to help me out? I looked at those in the search from eBay votto posted, just not sure of the differences in the brand/model.

[bzubke1]

I ended up going with a non fused distribution block and a fuse holder. It was just cheaper.

Cigars, I think we just need to know how many, and what amplifiers you will be installing.

Ah, I have two.
