i just got into car audio and also just ordered my 12"bl and i mostly listen to rap and im wondering whats the best tuning for the fi, where it hits the lows awesome as well the the mids and highs?....any feedback would help

if you want all 3 ranges to be "awesome" then you must go sealed.

Going sealed, though, will have lower output compared to a ported box in a more narrow range but the sealed box might have a higher overall average output... but it shouldn't.

If you set your crossover on your amp soon enough, like around 60-70hz, ported should still be the way to go to get really deep low loud bass.

Tune the box to around 32hz.

If you have experience with ported in the past and know what this tuning sounds like and want the low lows, tune at 29-30hz. By tuning that low will typically cause the higher frequency range for the sub to be audibly lower in output. So will 32hz but the lower you tune, the lower the frequency will be at the point of roll off above tuning.
