a couple years ago I scored some soundstream class a amps off ebay for about 220.00 apiece. My 5.2 was 1/4 of a watt X2 at 4 ohms and 500X1 bridged at 1 ohm. the 10.2 I know is 1000X1 at one ohm. My system was rated at:

1/4 X 2 for subs and 25 X 2 for the mids/highs. They look really nice too.

Old - 95.5 SE with lot's of mods.
New - 98 Black SVT with few mods.
