At one point I wanted to have some nice sounds in my vehicle so I bought this single 12 with a built-in amp from Micky shorrs at which is an authentic speaker store. My car ended up having electrical issues so I coudlent have the speaker installed. Therefore now I never hooked it up or even have the chance to use it nor even hear how nice the sound is to be. Selling it for a very fair price compared to what I originally paid for it because I have no use for it now and no space. The speaker is 100% brand new never used. I even have the original box.
