I have one of these in the trunk of my 92 accord in a ported box i made and its paired with a 150w rms kenwood amp. When i turn it up, my mirrors are just about totally useless, just a blur. People can hear me over a 1/4 mile away (me and friends have tested this). I bought a small spl meter that maxes at 125db, and well, it gets maxed when my bass hits. I would like to find something else to see exactly just how loud this is. People always guess i have at least 2 subs with some big power, but nope. Just this one kicker 12 and a small amp. If you are looking for some serious thump on a very low budget, this is for you. You wont be dissapointed.

Cons -
Neighbors dislike me
bolts coming loose on car
broke rearview mirror
