Last week at the Laughlin riverrun I went to the J&M booth. I had their speakers installed and wow big difference they sound great!!!( much better bass and of course the highs too) but while I was there I heard the speakers with the amps the 250 w was incredible. and the 500w with 4 speakers was really really incredible. anyone considering any of these upgrades I highly recommend any of these.. for 293 installed the speakers are a great value and more than enough for most people. For those that want something amazing go with the amp speaker combo with a life time warranty on the speakers you cant go wrong.
