CVR 15 sealed sounding like shit

[PESteele 10+ year member]

i sold my cvr to a friend and built like a 2.5 cf sealed box for him and it sounds like ***. I tried with and without polyfill and it was the same. Also it has pretty much no response below 45 hz. You can barley hear any bass on late nite tip. This is run off of the stock hu using a loc. His wires wernt labeled so i had to guess which was pos and neg when installing the loc so that might be the problem. Can you help me. do you think it would help to try and port it with some pvc's

need more power.............. and yeah that stock head unit/loc combo probably has alot to do with it. it won't hurt anything just to switch your speaker leads and give it a listen

Check and make sure you don't have the coils wired out of phase. Take a 9v battery to the speaker leads and see what it does.

friends got a cvr 15 sealed also, w/ a kx450.2 and sounds great. so i'm pretty sure it's not the lack of power thats causing it..

More than likely your wiring. I screwed up with a LOC and the sub barely moved at all. I unsoldered the wires and tried them out. When it was good I just soldered them again and everything was okay.

and why not enough power it puts out 600 @ 1 ohm. The sub has an rms of 500 which is how much i had going to it ported and it rocked

sealed boxes take quite a bit more power to get "equal" results as a ported box. most likely your loc tho.

Take the sub out of the enclosure and reverse the wires going to one coil and see how it sounds. This can't hurt and if it still sounds like ***, switch it back because you have problems elsewhere.

I have 2 CVR 15's in my room each in 2.2 cubes sealed running off of a 200 watt house amp and they hit the low notes on late night tip just fine

ok im thinking its the loc to. But also it seems to be overexcurting like mad cause hes getting like 1.5 inches from it where as when i had it ported in 4 cubes tuned to 35 i got 1 inch at most playing all out on late nite tip
