I should be fine with the BX1000D. It's rated at 1000rms @ 1 ohm. I'm running 2 MA Audio 120XE's which are rated at 350rms each. So, if the Hifonics amp is a bit overrated, that's fine. Anything is better than this 760W Pioneer amp I'm currently running. What a piece. First, it started fading in and out. Now, it's fading in and out, but even when it will power on, it's not putting out much power at all because the subs are barely moving. I knew I would eventually have to upgrade the amp because the subs would be underpowered by it, but I thought it would last more than the two weeks that it did. Pitiful. However, it was a freebie, so whatever.
