no i dont .. if they were buying Best Buy products and didnt wanna spend too much . i usually recommend them infinity speakers or Kenwood for a better sound quality system. If they wanted a little more bass i would recommend them Alpine since it has a little more punch and decent sound quality. If they just want to be loud i give them pioneer.
Our best selling speakers are either Kenwood or Infinity Kappa's. Amp wise best selling would probably be alpine amps, the F300's 50x4.
