You would need a small amp. I wouldnt use a 600 rms alpine to power a 300 watt sub if that's the max or rms on sub.Try to find a amp that's close to rms on sub.For example 150 watt rms sub 300 max. I would use 150 to 200 rms amp. If you go with that 600 alpine you prob will be buying more subs real quick.That's a high risk on blowing the sub.
