Just curious what people on this board have for sound in their cars. I have actually spent the last few years heavily involved in SQ type car systems. You wouldn't believe how hard it can be to find truly audiophile grade components for a car . . . anyway, here is my system: Head Unit: Sony 8850 Has 7 band EQ with 8 customizable presets, DSP, time alignment with seat position selector (HIGHLY valuable for getting imaging in a car), and a an anti skipping cache. This was a Mobile ES unit from a couple years ago before Sony bastardized the line . . . the new Mobile ES is junk . . . Amplifier: Xtant 603x. This is a three channel amp that tests out at 90 watts x 2 up front, with 360 watts into 2 ohms for the sub channel. Has built in 24 dB/oct x-overs and a built in noise gate. Audiophile quality. Processor: Xtant P500 A 5 band fully parametric (each band is 20hz-20khz, 1-10 Q, -+18 dB) EQ. Subs: Two Oz Matrix 200L 4 ohm subs in parallel. Loaded in a 1.5 ft^3 box ported and tuned to 28 hz. Anyway, its a very nice system IMO. I am thinking about adding some rear fill to get better ambience.
