Harman 230e disco amp. A little cosmetically dirty but clean sound. The selector switch is iffy so I run a dedicated line in aux. Pre-amp works. Lights up, plexiglass not bad. Can run full volume this setup. N crackles switches work, maybe a clean. Bose Acoustimass 5 subwoofer that satellites to Mission 7 series. The Bose is the crossover and deletes lows from the Missions, which are superior to Bose satellites Bose provided. Very thick speaker cables not long (included), and you get clean LOUD and cheap.
