Need Help Picking A New 4-Channel Amp

[Equnoxe]

Hey, well the MTX is not cutting it for me anymore. So I want to upgrade and finally see what these puppies can do.


These are the components I have (all 4 doors)

(RMS): 100 Watts
(Peak): 300 Watts

This is the amp I'm currently using

50W RMS x 4 @ 4ohm


The budget is 150 around.

These are what Ive come across so far that I liked,

I'm really leaning towards the "bass inferno" Ive never heard of them, but they seem to have the best bang for the buck, at 4 x 250 watts @ 4 ohms for 110. or the Quantum audio at 4 x 400 @ 4ohm for 140, which would give me space to upgrade.


Thanks, Andy
