| The base sound system sounds great until the windows are rolled down. Can't attest to the kicker system, but for the price I can tell you that you can get something much nicer for that amount of money.
Stage 1 from Mopar is coming out soon, should be about a 30-40 HP gain. Stage 3 is rumored to be about 450 HP.
They are fast stock. Many people are getting down to 13.8 1/4 mile times.
They recommend 93, require 87 but with 87 don't plan on doing any performance driving. It will likely retard spark hurting performance and fuel economy. I ran a tank of 87 and dropped a few MPGs.
What is able to be done to them? Anything I guess.....not sure exactly what you're asking.
