Sony's Red "Xplod" series was CRAP...no doubt. Their new range (black stuff) is alot better, and now competes with most of the major brands as far as dollar for dollar goes.
Remember guys, the way a system is installed and what car its installed in will make a HUGE difference to the way a system sounds. You could even get 2 of the exact systems, one installed by an experienced proffesional installer and the other done by the owner....you wouldnt even be able to compare the two when listening.
Ive said this a few times now...installation can make or break a system.
