Which old school amp is going to give me the most power? MTX vs. Kenwood

I am going to be powering a Arc12D2 in the back of my Tahoe in a 1.25 cuft sealed box. I am looking to see what amp is going to give me the most power to the Arc 12 at 4 ohms bridged. The 2 amps I have coming my way are:

MTX Blue Thunder Pro 752:

RMS Power measured at 12.5 Volts DC:

37.5 watts x 2 into a 4 ohm load with less than 0.05% THD+N

75 watts x 2 into a 2 ohm load with less than 0.1% THD+N

150 watts bridged into a 4 ohm load with less than 0.1% THD+N

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

90 watts x 2 into a 4 ohm load

165 watts x 2 into a 2 ohm load

325 watts bridged into a 4 ohm load

AND

Kenwood KAC-827:

Rated out put power:

85x2 @ 4 ohms

160x2 @ 2 ohms

300x1 @ 4 ohms bridged

Now the thing is I know that the MTX is under rated and test out between 70 and 80 watts per channel at 12.5 Volts which comes to at least 350 watts when bridged.....probably closer to 400 watts from that little beast.

The question about the Kenwood is what voltage is it rated at and is it underrated like most amps from that generation (RF and MTX)?

Thanks for your imput

can you test both of them when you get them and get real world results? And I'd rather have the MTX over the Kenwood any day, even if its rated less...

I mean I can test them by hooking them up to the sub and listening, but I was hoping there have been real world results already and someone would have some knowledge of it.

I don't have the equipment to measure actual output (wattage)

mTX I have seen the Blue thunder pro do 380 watts on 14v bridged not bad for a 75 x 2 amp!

MTX all the way

the TA 7801 is 1200watts and about $250 but does anywhere from 1400-1700 on the birthsheets
