I have built a pair of subs to match my DIY bookshelf speakers, they're pretty basic and only need about 50 watts each max. I was thinking about getting on craigslist and buying the cheapest amp or receiver I could find just driving them with that and building a passive line level crossover. I found some good instructions here and this would still be an easy way to go.
An alternative would be to buy 2 of the cheapest plate amps Parts Express sells, which would still cost me about $90-$130 which is more than I'm looking to spend, the MDF I got for $10 from Home Depot because it had been hit by a forklift and the 12 subs I'm using were free, I already had them laying around from my first ever failed speaker overhaul project. So I'm looking to power these things for bottom dollar and I got to thinking. Maybe I could build a pair of "plate amps" pretty cheap. Buy the parts for two 50watt max power gainclone amps. Then I just need the crossover. I could use the passive line level crossover I linked to earlier but I was thinking I should be able to build an adjustable line level low pass crossover. Afterall the cheapo $50 parts express plate amps have them in them, they can't be that costly to implement so maybe I could build build those too and just have my own sub plate amps for less.
Could anybody give me any advice or point me in the right direction to get started on this phase of my project.
