Summary: This is a decent subwoofer, but I was surprised with the sound levels it was able to achieve. I purchased this unit to replace a single JBL GTO804 which had a torn rubber sound. I was looking for something that would play lower frequencies at higher levels. My vehicle has a trunk and I first tried the BT1214 positioned in the recommended location, next to the passenger side wheel well and pointed towards the rear of the vehicle.
Pros: It will play low frequencies at high volumes. Installation is a breeze, find a spot to put it and secure the mounting straps with four screws, connect the leads and you are done.
Cons: The single biggest con is the price. For the price, even with Crutchfield's free shipping, I think it is too high for what you get. At $175 or lower I think it would be an better value.
Summary: Ever since I got my first bazooka 8" I'm hooked to improving my car audio. I've tried many boxes in my mustang convertible with its tiny trunk space but it seems that I've ended up with bazooka again. I've swaped the component subwoofer with a Kicker CVX 12" hooked to an amp and it was awesome! BUT I got married and now it's too much for my wife so I have to take it out.
