Well, at almost 8 years old it was finally time to do a (somewhat serious) stereo in the SS [img]smile.gif[/img].
I probably have about 20 hours into the install (and several hours each from Tully and Trevor Gould)......did I mention I'm one meticulous dude? Came out pretty nice though.
Here is what I did :<UL TYPE=SQUARE><LI> GM head unit that I already had (out of a 98 Venture Minivan) : lets my Venture rear seat radio controls and Monte Carlo steering wheel controls both still work. Also fader and balance knobs both still work as OEM. I wired it so that when the rear seat radio is activated (or, you fade it all the way to the front), it turns off the subs.
<LI> Line-level converters (lets me wire the head unit into a regular amp).
<LI> Amp : Planet Audio 5 channel amp, 50x4 (RMS) for the mid/hi, and 200x1 (RMS) for the subs. 2 ohm stable as well.
<LI> Subs : Two Pioneer 10" Freeair, firing into the backseat.
<LI> Rear Deck : Infinity 6.5" Components, mounted in stock 6x9 locations
<LI> Front Doors : Infinity 6.5" Components, mounted inside the doors. [/list]And for those curious, it added around 30 lbs total to the car. At least it's in back, where it helps cornering and traction [img]smile.gif[/img]
I took a lotta pains to hide wiring. Amp power wire is mounted INSIDE the front fender, so once it's about a foot from the battery you never see it again. I mounted the line level converters and crossovers inside the trunk, on the underside of the rear deck (I took the opportunity to relocate the RCDLR module to the left trunk hinge and hide it's wiring, as well as put the third brake light wiring.....now an LED light.....entirely on the top of the rear deck). Amp and subs both mounted to the Scott William's Trunk Kit Baffle Board. The crossovers (heck, the subs and amp too!) are basically hidden unless you stick your head inside the trunk. Similarly, all four component speakers are hidden inside the car under the stock speaker grilles. If you looked in the interior from the outside, the only sign that it is a "non-GM" stereo is the SkyFi XM Radio receiver on the center console (behind the T56 shifter, in front of the Bonneville seat controls).
I used the power antenna lead from the GM head unit as my amp turn-on wire. Works like a champ!
I can still (just barely) bolt in my spare tire to the stock tie-down using the WADA with stock J-hook and wingnut. It is a 17x8.5" SS wheel with 275/40R17 tire (25.7" diameter).....note that clearance is close enough that it would NOT have worked with a stock-size 255/50R17 tire (27.0" diameter) or the stock 28" diameter steel 15" rim spare!
Sound : still have a little "tweaking" to do (realizing that the stock head unit's lack of an EQ is gonna hurt me some), but it sounds LOADS better than it used to [img]smile.gif[/img]. Much crisper highs, great lows, and nice midrange.
Total cost : about $700 total in parts (some bought used...I love Ebay!). And like I said, a not-insignificant amount of labor....).
