I'm changing out all the factory speakers with Scosche EFX speakers and amps. The guy at Scosche is getting everything together for me .... I'm getting a speacial deal on everything ......Three amps, one four channel, 1 two channel and 1 mono block. Speakers and all the accessories to complete it. also Scosches 12inch sub box for the trunk. It's great to finally get a sponsor!
