First DIY project will be a Subwoofer, but ive not been able to source a budget plate-amplifier for a reasonable price in the UK. I need it to run a Peerless SLS 830667 and ideally would get a Dayton Audio SA70 70W, but they are only available on import via amazon, and shipping and taxes don't justify the cost. Any ideas where i could get a budget plate-amp? doesn't need to be a Dayton..
