Just installed bazooka tube model bta8100 series is bta 8 for size and 100 is the amp. I got this sub because all you have to do is plug it into the factory jbl amp. You have to order ther plugs from bazooka .Everything cost around $280 , only hard part was getting to the factory amp . This sub might not be as loud as the infinity bass link ,but you could install it yourself just plugs in no need to run a power wire just plugs into the jbl amp. If you want a little bit louder go for the 10 inch or stronger amp.
