buck was gracious enough to design me a 4ft^3 box tuned 32hz. im gonna be running them off 1ohm on a 1800.1D audiopipe. does anyone here have any experience with walls in a cobalt? i know when i turn the box forward and subs forward its much quieter unless its clear to the back of the trunk. and it only sounds okay moved all the way up facing forward (like a wall) is if the box is large enough to block most gap. so i dont know if sealing it off with some great stuff foam and running these as a wall would be better than all facing rear about 1ft from the trunk? just want some opinions.
