My arguments for both sides are as follows; 1. Installing the sound system because I'm sick of listening to the radio, haha. I'm not looking at a crazy system, something I will be happy with - If I take this option, I was looking at getting: 1x Kenwood KAC-M526 2 CH Amp 1x Kenwood KAC-M646 4 CH Amp 1x JVC CS-HX7158 7x10" Speakers 2x Kenwood KFC-55793 5x7" Speakers 1x JVC KW-R400 USB CD Player 2. Tuning would be for the weekend drives and/or midweek taking it to the track with my mate who drives a SS and is constantly talking smack about me keeping up with him on the road, haha. At this stage, I think the sound system would be the way to go - go for a more comfortable ride. Great feedback guys!
