So I am new to the whole Bass Cabinet/head stuff. I have been using nice combo amps for a long time. Decided to make the change and have been trying to piece together a decent set. I found a nice set of cabs someone was selling and I am picking them up tomorrow. It's a Carvin RL115 (1 x 15 -- 4 Ohm -- 500W) and a Carvin RL410T ( 4 x 10 --8 ohm -- 600W). I was just wondering what the community would reccomend to power these?
