    Will this mono amp work for 2 subs

    Hey I'm trying to see if this will work. I currently have the "pioneer gm-d8500m" mono amp rated at 600rms and 1200 peak. Specs also say 600 Watts x 1, at 2 ohms, 300 Watts x 1, at 4 ohms
    I've been running one sub but now I would like 2 12" subwoofers called the "infinity Kappa 120.9w" each rated at 350rms with 1400w max output. Their impedence can be switched from 2 ohm to 4 ohm. Together they make 700 rms and use 85.71% of the 600W RMS amp.

    I'm new at this and my questions are
    1. Is this setup doable with the mono amplifier and the impedence or do I need a new amp
    2. Is that amp going to damage the subs? I hear not to go below 75% and I'm at 85% but I've also heard that its better to go over than under.

    You'll be alright. Just make sure each sub is 4 ohm.

    ^^^Yup. That way you're at a 2 ohm final load enabling you to pull around 600 from the amp. It's funny, I had the same setup a few years back with the same amp. Lol! It worked very well for me. I put the subs in a 4 cu. ft. box tuned at 32. Some of the nicest sounding bass I've had. The Kappa's are great subs.

    My fraternity brother has this similar set up if not the same, sounds great and 2ohms will be ideal.
