The sledgehammer 12-in ported box

I gave it 5 stars because it's a bad azz box The 12-in MTX sledgehammer box. It's a very nice box. I love the carpeting. I love the front vinyl. I love the way my subwoofer recesses into the box ports big shook my car like a pro I love embroidering on the back of the box I guess you need a big box fror the slughammer sub that this box is made for I wish mTX sTill made the band pass boxes
Cons. It was a little bit too big for my Pontiac Grand Prix GT 2000 3.8 V6. I can put it in my car but I couldn't put it all the way to the maybe there's a way to grind down the fins heat sinks on the Bose amp or move it over? to fit it in back of the seat because of the Bose amps real bummer ????
