the mtx 8" 4500 4ohm model is just fine for a free air rear deck sub. you dont want more than that unless you want to tear the whole rear deck apart to put in support and sound deadening material. as far as the amp i dont know the output of it so it may be to much for the sub but if you want the most power bridge the 2 channels together- posiitive from ch.1 and negative from ch.2. find out the output of your amp before you hook all this up as the mtx 8 only needs 100-150 watts to be optimal
