Carputer help

[tdc3187]

I am going to put in a carputer hopefully within the next six months and I am trying to get some ideas on paper. So far I have a xenarc 7" touchscreen, probably a hp slimline maybe hidden in the trunk or under the seat, rockford amps for mids/highs and sub, a 3sixty.2, and dc-dc power supply. I know that the audio coming out of the computer is pre-amp and the volume can be controlled with the computer, but would it make sense to add a equalizer or bass knob for actual volume control. I really don't want to add a deck, and want to add minimal different controls.

Use the 360.2's volume control. It's perfectly good.
