Could use lower guage input holes for bigger amp power, doesnt have a bass boost.

Best of over all 12 inch subs i have tried.

Hard to find a second one to keep mine company. Shes all alone in my suburban. And my amp is only big enough to handle 4 of them.lol

I wonder why arent they as popular as other subs out there like kickers. I mean i had 3 12cvrxs they didnt match up to it at all.

hits seriously hard!!
if I want more I get a bigger amp or another bp-12

has to fit in the area you have for it,kinda big.But if it does stand back it will do 120 db plus!!!!!!!!!!!

awesome,I have a kingcab nissan PUP I have built subs for 20 years,I have always had serious bass but with a big box too.But in a pickup the bigger the box the less bass you would have because it makes the cab volume smaller,so what could I do ? all I had room for was a great 12 with a d-class amp,building a small sealed box with a 12 was not enough for me I am used to 120 db with 2 10's in a car.So I saw this used bp-12 went down there tried it and gave him the money before he heard it and changed his mind!
I think since the bp-12 builds it bass before it leaves the cabinent it has more low end.I have built bandpass subs in the past they hit good but not like this,it is clear punchy and HARD !!!!The only thing I built that sounded that good was 4x12's sealed or two EV 15's.
I am only using a 200 watt kicker d-class.

a JBL dvc 12,a kicker 4500 dvc(both sealed)
note:both of those were wired at 2 ohms the bp-12 is 4 ohms so it only sees 1/2 the power the bp-12 still beats it by far!

everything

takes a lot of room

I have never heard a sub hit this dang hard in my life. Not only do the subs pound like thunder they have ver presice sound. so its like getting a subs with major sound quality that pounds so hard. These subs are sicking and my whole cars vibrates, even the hood. all u feel in the car is extreme bass and the air numnbing ur head

This sub is out of this world. It pounds. It is the top of the line. With RMS 400 you can put 400 clean watts to it and it will bump so hard. It is very clean

sounds good at all levels and hz

none

I replaced 2 boston 10's with one bp-12 and omg this thing pounds! I am pushing some very clean power to it so I'm not sure how a cheap amp would run it ,but i can't see how this thing could ever really sound bad. I'm pushing it with a PG xs2500

Not having to turn your gain/boost way up to push your subs distortion free.The size of the box will fit in any trunk even foriegn models.

Your car better be sturdy and tight or this sub will shake and vibrate it to a ratteling bucket.

The Alumapro 12"Bp is the savior to us convertable owners and everyone around!!!(with-in a block that loves deep,deep,vibrating poundin BASS!)Nothing compares to it's hard-hittin,clear thumpin,back vibrating massage from a single 12"sub for the price.It should be in every convertable trunk.I use to bum-out while listening to track one of Sublime's 40oz cd when my top was down.I would lose so much bass to da sky even with two 12"kicker compVR in an enclosed Fosgate box with a L.A. strike SR2500 2channel amp.that I drove with my top up all the time.Well not ever again!That lil black box,that i can fit two of in my trunk but won't until I can make my whole car vibration re-enforced,knocks so hard n deep that i set every car alarm I pass at 25 feet and laugh as only a true lover of Bass can!So if you want to take your top down with no-shame and share your music with the hood then is single sub is a must.BOOM-RATTLE-RATTLE-BUZZZZZZZ!!!!!!

Super clear sound,gets really low.

Nothing at all.

I just bought the product today and let me say I love it. It is without a doubt the loudest single twelve that I''ve ever heard in a car. I plan on getting another so it is going to get quite crazy. All I have to say is if you buy the BP12 you will not be dissapointed in any way.

THIS SH*T BEATS!!! I only bought 1 for my trunk and a memphis 1000d amp, and the single sub beat louder than most people wit 2 JLw6's, Earthquakes, fosgates, vegas......nething u put it up against it'll beat

none, great sub all around....never distorts, hits consistantly hard, You do need a stereo with a db sensativity of 97 or better, which could be a weakness if u don't have the money. also u need a decent amp to push em.

i first used 1 bp12 with a depth charge 400 watt amp, and i wasn't satisfied. you need 2 use a midrange to good amp to push them. as soon as i got the memphis amp it beat like a mug. I only had money for 1 of em, but i know people with 2 usin the same amp, and you can't even sit in their car it hits so hard. most claim aroudn 150 db from 2 bp12's, and it's believeable
