Sounds kinda like crap

Well i had a pos no name single 15 in a vented box with a kicker 352i amp to push it. And it hit pretty decent well i sold that setup cause i just got all my stuff in today which is Hifonics 1500d and pair of kicker compvr 15's 4ohm in a vented box with each sub in its own space but 1 box. Its about 4.2 cuft each at 37. And imo my old cheapo setup hit just as hard. So im wondering if i dont have it wired correct, i messed with all the settings on the amp and it really was no huge difference from where i have it set now. Well for the wires i have the 2 + off each sub joining the + terminal on the back of the box same for -. Then from the terminal on one side i went into the amp's +/- then from the other terminal into the other +/- on the amp. With it like this is this giving my subs the power they need? Or mabey a different box?

did you find out from the company what the recomended air volume is, because some need more than others, and some don't work as well in different kinds of boxes.

Have you tried reversing the polarity of the subs ? Try switching the + and - going to the amp. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Well I'm reading your post again. 4.2 cuft is that for each sub ? Is your box 8.5 cuft box total ? //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

yes that is for each sub and the compvr 15's min is 3 and max is 5 so im safe.
