My brother had a nice Klipsch 10" 400w home audio subwoofer that we hooked to an inverter, thing would bump hard till you turned it up too much and the inverter went into protect. Actually did a good install on it, tucked all wires and everything. Inverter mounted under the seat, wire tucked to up to cigarette lighter, power wire tucked running from sub to inverter, rca hidden from headunit to sub. Was quite hilarious
