OK, my amp - Kenwood Excelon KAC-X4R. It fits PERFECTLY under the front passenger seat from the front. My question is... I want to mount the amp directly to the floor. There really isn't any room for a bottom piece to mount onto. One person used velcro - I want to drill. Should I just go for it with self tappers right into the floorpan? I looked the best I could - there "shouldn't" be anything I can hit - right? Fuel lines, gas tank all out of the way. Should I chance it? I really want it solid mounted.
