Gp High Output MDF Flat pack
Best Subwoofer DIY boxes on the market. This is the 2nd box I have ordered and am very pleased. Only problem I had is ordering a certain tuning frequency on website and getting the wrong tuning. Ordered 33 hz but got 30 hz. Not a big deal, it still sounds great
`GPcarAudio: Hey Brandon, thank you for your review. We noticed there was a glitch on your order where the tuning was somehow not selected. I am not sure who relayed me the message to do 33hz, but I hope you are enjoying it. Thanks again -
