A Thing of Beauty!

This little amp is rock solid! I drive a 1998 Dodge Dakota single cab truck and I have 1 JL Audio 10" W1 sub behind my passenger seat. Not a lot of room in a cab this small but this amp along with my sub can shake the hell out of a person! Much better amp than the old Kenwood I used to have. JL Audio makes great products! I won't buy another brand of sub amp ever again!
