Custom 15" Subwoofer, this was made by me and I used the motor from a JL Audio W7 AE and the basket from a older PowerBass 3xl. Every part and material this was made from was top shelf. Just this one sub will have you completely amazed. The SQ is there 100% and this thing get super loud. Definitely worth the money. This is a single 3ohm Subwoofer! 1,200 watt rms continuous power. This is a very high quality Sound Quality subwoofer that gets very loud and hits very low. If you want to stand out and have something that no one else has at all here it is because this was custom designed and built by me.
