You ain't done yet, sucka! Rip out all the M5's speakers that have a frequency response
above 50 Hz.Buy $5000 worth of 18" subwoofers, hack out the back seat and build a sturdy 1/2" plywood box back there to mount them in. Then go out and get another $5000 worth of Rockford Fosgate amps and mount them
where ever there's room left. Hopefully, you ordered the M5 badgless so that in their place you can put Honda Civic tags. Go down to the local Hip Hop music store and buy plenty of cRap CD's. Go down to the clothes store and buy some new threads that are 15 sizes too big. Visit your local brain surgeon and get a lobotomy, then cover up the scars in your head with a baseball cap turned around backwards.Get plenty of body piercings and tattoos. Finally, walk around slack shouldered staring aimlessly at the ground with a stupid look on your face. That would just about complete the picture in my mind.
