So I've had my car for around 2 years, and plan on keeping it for a little. Bow that I know I like it, and since I don't really plan to do many "performance" upgrades, I want to get a system. I have a 2009 Mazda 6s GT. What I'm thinking is two JL 8W7AE (8") and one 13W7AE (13"); being fed by a JL HD750/1 and a HD1200/1. Does anyone have a JL set-up that can comment on how it performs? I'm going to build the box myself, 13" in the middle with a 8" on either side, covered in black carpet matching my truck with a decent sized window(maybe multiple?) with red lighting/glow, and not sure yet what to do with the amps. While I'm doing this, I'm thinking(right now probably a 85% chance I will) about replacing all the speakers with JL Evolutions and checking into fitting a nice head unit, I would love something with internal storage(50GB+, or a SD slot? Or?) that plays FLAC(if it can't play FLAC then any internal storage is pointless IMO). Now I do have a question about Dynomat; it's worth doing, right? I plan on doing the whole car. I know this will be a pretty expensive set-up, but if I'm going to put the time in doing this, I want it to be worth it. Is there a better(higher quality, not cheaper) brand or anything I should look at? Thanks everyone. EDIT: My dads an electrical engineer, so once I have everything I'll just drive the 5 hours home(I'm in Tampa, FL and "home" is in Boca Raton, FL) for the weekend, so there's no worries about building the box or install or anything.
