I keep getting conflicting information

[royalstud44]

So I just recently bought 2 12" mtx 5500's with an rms for each sub at 300 and an impedance of 4 ohms. According to the mtx website the rec rms amp power is between 150 and 300. When I went to my local audio store today the worker told me that I needed at least a 750 watt amp because it is better to overpower the sub than to underpower, however, after some research online it seems that the opposite is actually true. Can anybody help me figure out how powerful of an amp I need to safely run my subs? Im trying to keep my amp price under $250 as well. Thanks.

Look for an amp that can do between 500w and 800w at 2 ohms and you'll be fine.

Luckily 2 ohm capable amps in that power range is the sweet spot price wise.

Interested in trading the pair for a MTX 8512-44? I need 2 more 12"s to match 2 already being ran.

I don't really want to trade because I think that an amp powerful enough to drive those two would cost me at least double what im willing to spend.

should i get a mono or two channeled amp?

Tell him, 'If its bad to under power speakers, then that mean I have to have it at max volume all the time right? Otherwise a hole has been poked in your thought.'
