Ease of Use
These subs hit hard! When I first purchased the I was skeptical because quality wise they feel pretty cheap... but to my surprise they sound really great. I have them in a custom birch octo-ported box 3 net tuned to 36hz, powered by a soundstream stl1.600d @2ohm. When I finally finished my install in my '99 Audi A4 I noticed that the bass is waaaay deeper when the windows are rolled down. If your doing a budget build I highly recommend these subs, but, make sure you get the right box. Also I would strongly Not suggest that you throw 1100 watts as they so boastfully claim... unless you want them to detonate. lol
Pros: Sound fantastic in the right box, the carbon fiber look cone is a nice addition to the cosmetic look.
Cons: Initial impression was they felt cheaply built. The 1100 watt claim...Negative!!
