Tuning help

[Acerockola]

Hello, I'm new to car audio and I just finished installing my new system. It's comprised of a pioneer deh80prs head unit, polk db6501 components up front and db651 in the rear. A JL Audio 360/4 amp, a rockford fosgate r500x1d mono amp and a p2d4-12 sub in a sealed box. I also have damplifier pro in the 4 doors and trunk. I'm running it passive right now as I learn more about how things work. I did the auto tune and it sounds really good but I think it could sound better. I was wondering if there is anyone near the western suburbs of Chicago that might be able to help with the tuning? Someone with equipment like a oscope or RTA and the know how of fine tuning a system. I want to get the most out of my investment. Thanks.
