K hope I'm doin this right. Thanks a bunch! I put my meter on it and found out it's a dual 2 ohm. Currently have a VT (virtual technologies) Hammer 10 in a T-line and hoping to switch to the FI with the same amount of power but with maybe a different sound. The VT is a dual 4 ohm (400 RMS) I have about 750 to it now. Hoping the FI will do better with more power? Hey you got your quote right! haha nice As far as output, i have no idea how tlines work. So i cant give you any hope for getting louder, sorry. I don't want to say something and have it be completely wrong. Cool, thanks man!
