So here is the situation, Im building an enclosure in a 2 door tahoe for a friend of mine. He is about to buy 4 15" Cerwin-Vega 154, my question is how much cu. ft. do they need. According to their website it says 2 cu.ft. per sub...that just seems rediculously small for 15's to me. However, Ive been looking around and I have read that some people had 2 of the same subs he is getting in a 10 cu.ft. box!!!! Im trying to start selling boxes around me so I dont want this to sound like **** when other people see it, he also wants it tuned around 25hz, do you guys think thats too low for a daily driver? thanks for yalls help
