I'd like to keep the Brutus for a bit. I have never had a issue with it and it powered that CVR pretty good. I mainly just want to keep it safe and not blow up a $400 Fi Sub. Box is ply oak at 35"w x 13"h x 22" deep. I have a 6" PSP aeroport in it at 14" or so long. Should be around 32hz Fill's damn near the whole cargo area. I'll post pics
