I got started on my boys Caddy this week. The goals: 1. Build a very solid daily system to pump the sounds while riding. 2. Take up as little trunk space as possible. (Need space for hydraulic set up) 3. Make it a clean install worthy of popping the trunk for. 4. Put some JL system to shame while spending a fraction of the cash. The gear: Kenwood head unit. Infinity 6.5 components, 2 sets 12" Fi IB3 subs, trying to fit 4 but may end up with 3. Sundown SAX-50.4 Sundown SAZ-2000D Lots
