Review: Easy bass Best if you buy an amp with bass knob control - Buy these they sound like a 12” set!!!
Review: 2nd Gen Rx350 perfect fit - For anyone with a 2006-2009 lexus rx350, this is the perfect fit for the spare jack under floorboard of the trunk. You just have to remove the scissor jack and the black plastic holder, then this fits it tightly with plenty of room to add an amp. The 10 and 12 inch kicker down firing models do not fit unfortunately, but this still improves the stock sound by a lot
