Audio Upgrade - Using Stock Head Unit???

[IndyCharger06]

I'm looking to upgrade my audio system. Not going crazy, just want better quality sound. I've had a recommendation to put in a CleanSeep CL441dsp, add an amp and replace speakers.

Problem, I want to keep the stock look and maintain the control on the steering. If I go their route I loose control of the volume. A separate dial is required. All other functions remain. I don't like the added dial idea.

Anyone made good adjustments, not spent a fortune and maintain full control thru the HU and steering wheel?

Ideas?

cleansweep is garbage. go with the audiocontrol units.

you can search interior mods for my system i installed awhile ago. it goes through each component.

I see this one, http://www.chargerforums.com/forums/showthread.php?t=28426&highlight=audio+system

But, I do not see much information on the signal processor.

Crutchfield is saying to use the Rockford Fosgate 3SIXTY.1 They also say it will integrate with the stereo and allow volume control over the existing dial and steering.

thats the one. the lc6 or lc8 is all you need.
