Don't know how to install equalizer. Where does

hi input wiring hooks up to speaker wire outputs on the stereo. in 2008 chrysler has no ignition or accessory outputs. everything is digital, if you use a trunkloc from PAC electronics you will be able to hookup your outputs from the deck into this unit and it will provide you with the RCA, and remote power output needed for your system to operate. the factory deck should have battery and ground at the plug but no acc.
