Went from a Alpine type r 12" to a Alpine type x 12", used the same amp on both... Found a place that will make me a vehicle specific box to fit a 15" sub. Going to be a Rockford 15" T1 2 Ohm DVC sub with a 2400W Hifonics Brutus. Plan on taking pictures of the set up, waiting on my tax refund should be here friday then I am buying the stuff. Thats really the only 15" sub I can put in my box because the Mount Depth won't be that great, and any other sub would be too big. Those 12's slammed for sure, especially the type r shit hits crazy highs. I'm just ready to get the lows, and a 2010 camaro is probably a little too small. Plan on getting a vehicle just for my audio obsession in a few years. Some kind of SUV... Thoughts?
