I'm sort of a noob, and I really need help. I have been blowing speakers the past 6 or so years (about 1 speaker every 2 years), I think from underpowering them. I am bad with ohms but each speaker is running off of one terminal so I think its at 4 ohms. If the rear speakers need 110, and the fronts need 55, what do I do as far as power? Because I can't direct an amount of power to each speaker as I see fit. Do I keep my amp or get a new one? Or for the same price get a different set of speakers for the front or something? Help me out...

My amp is: MTX Thunder4320

• 40 watts x 4 into a 4 OHM load with less than .1% THD.

• 80 watts x 4 into a 2 OHM load with less than .3% THD.

• 160 Watts bridged x 2 into a 4 Ohm load with less than .3% THD.

Dynamic Power (IHF-202 Standard) measured at 14.4 Volts DC:

• 85 watts x 4 into a 4 Oh load.

• 140 Watts x 4 into a 2 Ohm lead.

• 280 watts bridged x 2 into a 4 Ohm load.

Rear speakers are: Infinity Kappa 693.5i (6x9)

Power Handling, RMS 110 Watts

Power Handling, Peak 330 Watts

Sensitivity 95dB

Frequency Response 35Hz - 25kHz

Mounting Depth 3-3/16"

Impedance 2 Ohms
