I went a different direction with my car. Up for sale is everything you'd need to add a subwoofer to your car.
1- sound ordnance 2 channel amplifier m100
(110 watts RMS x 2 at 4 ohms (140 watts.
RMS x 2 at 2 ohms)
200 watts RMS x 1 bridged at 4 ohms
2- amplifier wiring kit (+,- and fuse)
3- plug and play add-an-amp harness that has a built in line out converter. NO WIRE SPLICING NEEDED.
4- 17 foot RCA cable.
