Tuned way too high

I used this with a Kicker C88. I ended up finding a used prefabricated box online that was slightly larger and was tuned lower and it did wonders for my sub. The Ground Shaker however is built solid as usual. Prefab boxes are just garbage in general unless they're built towards a specific model.

bass box

the quality of the box is great. Helps produce great sound for such a small sub. I was very impressed on how well my sub did in that box and quality of sound I was getting. At a good reasonable price.

Too big

The box is 1.24? If so then thats why my new P2 rockford 8 sounds like crap in it. I ordered a sundown audio e8v3. I hope itll sound ok in it. If not im going to throw away this box and get a custom one built.
