I'm not that great with amps, so I'm gonna need a hand. I'm pretty short on cash, but I could get some money soon, and I am in desperate need of a decent amp! I have narrowed it down to these 2... This thing and this one My price range is about $300 anywhere around there. Preferably 100w, 12" or 15" speaker. Speaker size is not that important too me. Thanks for any help!
