I just bought a single cab s10 not long ago. It came with a 350w max power powerbass sub with dual voice coils. A while ago my buddy decided he was going to sell off all of his car audio stuff and go to a competition grade set up. So he sold me an unused pyle 12 that maxs out at 1200w and has 2 4 ohm voice coils. (says blue wave on box) for $20. I rewired the PB sub and put 200w through each voice coil and decided when it destroyed itself I would build a box and get a new amp for the pyle. That was 2 or 3 weeks ago and its still going strong. I'm really suprised by it and now I'm trying to decide if I should sell the pyle and get a powerbass 12 or not. I would really appreciate any advice or criticism you guys will give me.
