Ok, well, I had a system in my old Bonneville, it was alright, noting amazing, so I thought I would transfer that over to my Formy. Well, had to build a custom box to fit on the shelf behind the back seat because I didnt want to spend $270 on a t-top box from subthump.com that only provided 1.1 cu feet of air space for each sub.

So, After I built the Custom box I put in the subs and the amp. I also installed my head unit and discovered there was already aftermarket speakers from Pyle. I also soon discovered that one of the speakers were blown and all of them sucked ass. I decided to replace those with 6.5" Alpine Type-S speakers that have worked out great.

So First Set up was:
Alpine CDA-9827 w/MP3 playback
4 - 6.5" Alpine Type-S speakers
2 - 12" Pioneer Subwoofers
Pioneer 760w Amp running 125w RMS @ 4 ohm to each sub
Custom Box I made out of 3/4" MDF w/ 1.5 cu ft of air space to each sub in seperate compartments.

It Looked like this:

Pretty soon I wanted more bass with higher quality so I could turn it up louder with no distortion.

I stuck with the same deck and speakers (they were doing fine and werent distorting) and then I chose to run the same amp to save money. I found that I could easily run a pair of JL audio 12" W1s.

I changed the setup of the amp (bridged it) to run 190W RMS @ 4 ohm to each of the subs. I think that the new set up sounds great, and its loud, we had a dB meter that only went to 126 dB and my system topped it out, so I dont know exactly how loud it is. Just my speakers with the subs off hit 110 dB with no distortion, which I think is pretty decent.

New Setup:

Also here is a pic of the tint on the back window, please note that the amp is about 1 inch from the glass and the subs maybe 2 inches, so i think the tint hides them pretty well.

I like the rims you put on it. Looks really good. I'm going to be putting a sub box in mine soon however im just going to buy the custom box from a friend it fits right where the ttops go will get better bass. I'm wanting to get my windows tinted next year though so we will see. How do you like the jls cause actually im going to be getting a similar sit up just different amp and box.

Hot Formula. I like the rims. Where did you get the door "formula" decals? You said you wanted a 6 speed...I wanted an auto. A friend of mine who had an 01 Formula convinced me. He drag races his all the time, runs 10's. He said the 4L60E is faster than anyone can shift a T56 manual and that the gearing is perfectly controlled. Plus my wife can't drive a manual if her life depended on it. I love my auto too. GM did it right.
