Just wondering if the factory radio (02 GT) comes with pre-outs on the back? Also, 6 months old...2 10" alpine E series in a box, and a 400W coustic amp..what would be a good price for that? A guy has some for sale for $400.00 with the amp. Or would you go with 2 10" Xplode 4 months old in a box with no amp for $100.00? Which would you go with??

No it does not have outputs...if you want to use the factory stereo with an amp..u will have to buy a line level converter ...

And the alpine is a little pricey for used...IMO..
I'm not a fan of Sony subs at all!!!!
