If this is a DD, I'd advise against a STRICT diet.. You'll regret it when you can't hear shit after an hour in the car. It might be fun at first, but after a while it isn't. Yes my car is loud, is it fun to drive?? Not for more than an hour. I've gone through three sets of speakers and a head unit in 7 years. But if this is a dedicated track car, trailered and what not, than just GUT it.. I mean GUT it.. Long story short, I polished up my AC components and reinstalled it and spent abotu 6 months trying to get that car quiet in the cabin again. Gutted the interior, dynamat and roll-on truck bed liner.
Here's a list, but not the one I was looking for..
