I got meself a cheap amp,2way-150w,or 1 way 300 with low pass,after hooking it to my boss 10" sub I had kicking round(1 of 2 subs) it was a right farting sub,so I downloaded a sub enclosure design thing from blaupunkt called blaubox,should I follow this,or would any enclosure do?-I dont plan on having it ported,I was gonna do it a basic square with the sub on a slanty edge,to fire into the car,what have you all used?
