Featured Wiring help for cooling fans

[Garrett Morgan]

Howdy y'all, starting a build, and I'm concerned about heat from my amp given the location I've got planned out for it. It'll effectively be sitting in a cabinet, and I'm planning to cut a hole out in the top and using two PC fans as exhaust fans to try to keep it cool.

My question comes down to wiring, and I'd really like to run it past y'all to either see if it works and find other solutions if it wouldn't.

Here's some truly awful MS Paint work to show what I'm thinking.

Red = Positive
Blue = Remote
Black = Ground
Green = Relay Connectors

In words, because I **** at MS Paint, and I don't know how to draw electrical diagrams;

My plan is to wire the pos, rem, grnd from the amp to the relay. The powered output from the relay, split to power the fans, the negatives from the fans combined and grounded at the amp's connector.

The goal is simply to power the fans, and have them kick on when the amp turns on.

Ah, and the reasoning for the location is that I'm building the enclosure for the amp across the entire span of the cargo area, with the sub kinda centered, with a separate cabinet to the side for the amp to sit in. The whole thing being upholstered, trying to keep it relatively stealthy, and trying to maintain a good amount of cargo space.

I'm about to do something similar but I'll get a fuse box and tap into the rear daylights for the relay. I really don't want noise\feedback from the fans in my amps but maybe I'm over thinking it.

I wired mines from the power and ground distribution blocks in my trunk. Wired power to a relay triggered by a turn on wire (from one of my amps) and then to a thermostatic switch that is adjustable. From the switch to 4 pc fans. A little complicated, but it works for me. I did Google searches for wiring diagrams and used my experience with wiring to configure my setup.

Your wiring diagram, for the relays, is correct.
