The amp is mounted in the middle of the seat for now tell I figure out the problem where its been since I hooked it up, I hooked the speaker and amp up after I got both of them I know how to hook a system up not that retarded but the 1 ohm one was different but Fi got me a giagram and I wired it according to the chart and it all started from the start it was doing that so I figure its the Amp not being tuned right cause when Fi called me and was telling me what to do and I set the Subsonic down lower the speaker didnt do it at the volume it had been doing it , it made it where it had to be turned up loader.
