This is a system designed by Elite Auto Sport.  I was invited to join the install team to put the whole thing together on a 2005 Chrysler 300.  The end result is very sick and it actually “shook” my house!!  I was afraid that the neighbor would call the police or something.  Elite Auto Sport did a very good job making the custom box and amp rack, and the paint job is very professional too.  Just in the trunk, we put in 2 mono block amp to power each sub, 5 Farad Capacitor for each amp, and finally a 4 channel Sound Stream Amplifier to handle the mids and highs.  Thank you Elite Auto Sport, I had a lot of fun working with you guys!
