Congrats man, do the big 3 now and you're good to go.

If you plan on adding more power later, grab a nice alt from one of the companies I stated back. I've dealt with the alts that were posted db electrical, ebay and they didnt last long, didnt do rated power output either. They worked well for others, but didnt for me and quite a few of my other audio buddies.

Feel free to pm me if you have any other questions, I'll help the best I can.
