Scott, I'm thinking about this Alpine Type-R shallow. http://www.alpine-usa.com/product/view/swr-t10/default It calls for an enclosure volume range from .25 to .5ft^3. The Thunderform and Stealthboxes are .6 What's the best way to take up some of that space to make this work within the optimal range? is there? Also, considering this amp if I don't go with the 5-channel. I just really want a dedicated amp so i can get some more power. If I do go with a 5-channel, I may have to grab a different sub because that one is hungry. http://www.sonicelectronix.com/item_29867_Kicker-IX1000.1-11IX1000.1.html Anyone got any thoughts on the best components and coaxials for the doors? BTW, Disregard prices. Those can both be found for about half.
