ok, I got 2 10" 500 watt Orion Extreme's with dual voice coils. I've got the voice coils wired in series and everything done up good. Right now, due to my budget at the time, I have a 300 watt Jensen amp. It's not great... but it bumps pretty good. I need a better amp for more power, but I don't know what's good and what cheap. I'm looking for good sound, with a good amount of power, for a relatively low price... any suggestions?
