Must use component speakers with cross over, for better sound and more power handling,4x100rms using a 4 channel amp /cross over integrated to cut the low bass on the amp for the sound, Add a Mono amp 1 ohm stable (best)the RMS power of the amp matching the subwoofer power by 75% for the amp, keeping a 25% security power for the sub, same for the sound amp and component speakers, A good balance sound system can drive at maximum level without distortion and burn.
4 gauge power kit, condenser 1.5 farad ( save your alternator life)
