Basically I needed to downsize the bass on my rhd 93 mr2 because I had an orion 12 that took up mad space in the whip and because of the complaints, the overkill inaccurate bass and the waste of space I was thinking about an 8" sub. Because of my prior experience with jbl amps i knew this looked good, and boy this thing is not even even broken in and it hits almost all types of bass hard excluding the extremely low frequency's, shes running at 220rms with a Cerwin Vega sx220.2 and matched to the 7" bd small truck box.
