These subs hammer. I have 2 of these in my s10 in a 1.2 cu box or each sub. Then hooked up to a 2000w mono. Running 450 to each which just above rms power which is good for subs. And these things pound. I've already gotten pulled over for having these things. I see no cons about them yet. They are loud, clean, and easy to clean. All materials seem durable and I've had them for 6 months with no issues. I highly recommend these subs.
