I am looking for one those 'powered subs' with the amp built in, I used to have a bazooka tube one, I found this one on amazon http://www.amazon.com/PYLE-PLTB12-12-Inch-Carpeted-Subwoofer/dp/tech-data/B00022OBPQ/ref=de_a_smtd is it one that has an amp built in so all i have to do is run wires to my radio?
No, this is just the subwoofer and does not include an amp. The description states passive which means that it does not have an amp.
