I disagree with the radio statement. I use a Clarion DRZ-9255 in my competition sq car.
My HU isn't the best sq but I can watch Netflix,Hulu, and anything else off the net going down the road.I remember older decks I had I was thrilled that they could change colors or play a small clip over and over again. So in that aspect the newer radios beat the h3ll out of the older ones. I've had some sq HU's and the sound this pioneer 8500 does isn't that bad+ web browser,GPS,play games using touch screen. Pull up weather, play my pics and vids on screen, check Facebook, turn on phones camera and it shows on screen of deck, hook up a hard drive for days of songs and vids,Backup cam, list goes on and on so this new radio beats any old school deck I had in the past hands down!
I haven't checked on this deck but I think pioneer is still 98db snr with 4 volt pre outs. I will admit a 115-118db snr old school HU with 8volt pre outs will sound a lil better but god the things I can do with this radio is worth the lil give up of sq
