Hey, I've been looking around for a while into getting to build some DIY amps, and I would like to start by building a moderately powered (100W or so) subwoofer amplifier from a kit. The only problem is: all the kit's I've found are for full range amps. I would really rather not use a full range amp to power a subwoofer because: 1 - It is a waste and 2 - a cheap full range amp will probably sound a lot worse then a cheap amp designed to go from 10Hz to 100Hz. If you know any place where one could buy a subwoofer amp kit *Preferably in Canada,* please share the knowledge. Thanks.
