That does Bodrulm123 no good, as he doesn't have the hi-fi or HK system. Bodrulm123, you need to access one of the underseat woofers and tap the wires leading to it, send those to a subwoofer amp that has speaker level inputs. You only need to tap one, low frequencies are summed to mono so there's no need to tap both woofer wires.
