I have been using the FAST-9999 for a few weeks now and have had no problems with it. It was a little tricky to install at first since I didn’t have a factory-wiring diagram to follow, so I didn’t know which wire went where, but after some trail and error I finally figured it out. Just use common sense and it comes together pretty easily.
I have ordered a number of car stereos from Sonic Electronix and all come in excellent packaging, shipment was fast. and the deals were great, and as long as the deals are great Sonic Electronix will be my #1 Place to shop for stereos.
