No I got that, sry for the confusion, my fault...amp is rms 500 at 2 and 900 at 1. Heard sd-2 can take more than rated, just need to know how much more to decide which way to go. Again thanks for the help.
Curious about actual rms power anyone has ran continually to sd-2 10inch at 1 ohm with no problems? Trying to decide between 2 & 4 ohm sub. Thanks for the help in advance
