Bought this around 2001/2 and used it to power a sub in my old mk2 CRX. It's a two channel amp, cover says maximum power 2x150W. Has a single stereo pair of RCA inputs, gold speaker +/- connections plus 12v power, remote switching and ground. On the top you've got output level, bass boost switch, a HPF/LPF selector with a dual adjuster for each, and a pair of status LEDs. Would be great for a retro build.
