Thanks in advance for any help or ideas you guys may have for me. I just recently purchased a new Kicker CVX 12 along with a superbass probox and am just not nearly as happy as I thought I'd be. (Never used a probox before and didn't know what to expect). Anyways, I listen to mostly rap and love the low bass. I was thinking that a ported box tuned around 32 hz would be very nice for this sub in my trunk. Kicker recommends 40 and that's what the probox is tuned at, but I just can't get the lows out of it. Anyways, I'm new to all of this so think "rookie" and please don't be afraid to be very detailed and give any opinions you guys may have. Thanks guys!
