Right now, i have a 1000watt amp, going into a vented box of 2 12inch woofers. I was thinking about selling the box and keeping the amp, then getting a smaller single sub. The box weighs SO MUCH and i honestly hate feeling like there's an extra fat person sitting in my trunk. If i got something smaller, it would be lighter. I don't exactly know what to do though? Should i get a single 8,10, or 12 inch? I was probably gonna sell my box for somewhere around $200 then use that extra money towards a smaller set up in the trunk. Also, is it bad using a 1000 watt amp with only 1 little sub? I know it's bad if you have 2 giant subs and then a tiny amp, but is it bad if its the other way? I'm new to all of this stuff also, please don't destroy me if I'm wrong about things lol.
