Stereo upgrade project 2016 M6 GT

Figured I’d start a post as a place to log my progress. I’m figuring that this is going to be a 6 month project if I am lucky.

Goals aren’t that crazy:

Keeping factory HU with PAC aoem-maz2 for integration.

Infinity kappa 6.5” three way components in the front doors / dash using factory location.

Kicker comp RT shallow 10 in the trunk above the spare.

Amp is a Rockford Power t1000-4ad, which will give 250w to each door channel, and 500w to the sub. I plan on using HU power for rear fill.

I’ve done lots of stereo projects in the past and each has something I end up regretting. Usually because I get impatient trying to work fast. So I’m giving myself all the time in the world for this one.

Getting started in earnest

I strongly recommend figuring out a way to get forced ventilation (airflow) through the amp section of that box; I suspect you're going to regret it in a major way down the road if you do not. You'd be utterly shocked at how fast electronics that are running material amounts of power get hot in confined and reasonably-insulated spaces (which that space definitely is and will be!)

Plan is to build a new carpet piece which will have integrated mesh venting for the amp rack and the sub. Will also (maybe/probably) run a cross ventilation fan like PAC CF-1. Like I said it's gonna be a long process!

IMHO two small box 12V fans (e.g. 80mm) at opposite ends of the box (one push, one pull) wired to the amp turn-on circuit so they run when the amp does and establishes a positive airflow through the amp box. Fortunately they're trivially and cheaply available (PC fans are 12V.) That'll do it; you don't need a lot of airflow, but you do need positive airflow. Sleeve bearings are fine if they're mounted vertically.

This is going to be nice.

How is your tuning going to be achieved? Are you going to run a processor of some sort?

As of right now no tuning. Trying to keep it simple. Front stage will be well powered passive three way, rear fill from HU power, modest single sub in the trunk with adequate power.

Haha sadly 99% of my listening in the car these days is podcasts anyhow! This is more of a passion project than anything else ... a chance to take it slow and get as close as I can to something I’m happy with, as a white collar shade tree hack who is relying on his 12v self-training and 30 year old middle school shop classes (supplemented with some YouTubing).

Dunno about you guys but I feel like 75% of my “work” on this sort of project is just staring at stuff.

Glued and screwed



Decided to use the router for some cross vent holes on the amp rack while I had a jig set up.
