I've decided to just run 6.5" coaxials in the doors and 6x9's in the rear of my car run off of deck power. I've heard so many success stories from guys with early C4's doing this and then just running a nice 10" sub with a small amp. I'll try my 12" first of course, but I have a feeling that it will be too much, as it made quite a substatial boom last time I used it. Anyone here ever used deck power and had a really nice system? My deck will put out 30 watts RMS into 4 channels and has time delay, a built in EQ, etc, so it should run 4 speakers decent enough. My old 18 watts per channel RMS deck still does the trick in the charger, so I guess this setup will work in the vette. All this time the simplest setup was the one I was looking for, It just took some time to realize it.
