Finally got another spark since my first one was totaled. First thing I wanted to do was upgrade all speakers, headunit and a sub.
I ended up with the Kicker 41KSC44's for the front and Kicker 41KSC464 for the back. Also got a Sony XAV-W650BT headunit. Install was pretty easy and it sounded amazing. Only problem was very little bass. I figured that would be an issue because of the small speaker size. Not to worry though because I just took the subs out of my truck. Yea 2 12" Kicker CVR's might be overkill but I am loving it. Now my spark is quite the little music box.
