great bang for your buck!

Wow I was very skeptical when I first bought these sub's , but I have to say they really pound with the right amp and install. If you want some good bass @ a low price I would pick these up.

Bump

I love these subs. They pound really hard. So much to the point, my rearview won't stay in one position anymore. I didn't buy the subs from here but they are really good subs. For the price here, they are really worth it. I paid 200 for both of them because I didn't buy them off of here and they were still worth it!
