ok i j/ went out and looked at it and here is what i got, dont know if this will help or not. 2 12" DEI Pro Plus subs in the box, set of places to put wires on both sides of subs. the amp is a DEI Audio Mobile Power Series model 2101. on one side there are a freq, bass, and gain turn nobs with arrows on them, a little thing to switch from HFP to OFF to CPF. there is also a status light and 2 red and white plugs for the input and output. and on the other side there is a spot for speaker + - , fuse 30A, and a spot for +12, REM, and GND. that is all that i can see. i hope that helps a little. if not, are there any other ways i can find out about it? i went to the DEI site but they've updated everything. all help would be appreciated.
