if you got more power, the type x will be louder and sound much better doing it than the type R, tyoe R is still loud though and does sound good, but not comparable to the XYou could feed that Type R just as much as the X, and it will be louder IMO. Make youself a large ported box, and feed it all you got, just SET YOUR GAIN CORRECTLY. I guarentee that your problem before was that your gain was set incorrecting, sending a clipped signal to the sub.
