Hi, what do you guys think about this amp. I was gonna buy two of these today brand new because i should be getting back my 100w rms polk mmc690 6x9's any day now and they seem to want alot of power. Someone told me they are only like 65% efficent speakers and that it takes alot to power them. I figured two of these amps, one for each speaker would really make them sound good. I also figured that if the need arose I could use them to power my sub or another sub. the price was right at 70 a piece brand new but i am concerned they may not be all they are cracked up to be on the box.

Wow... what a contrast,
The polks are very good drivers, specially the momo series u have chosen.. and the Pyle amp you have chosen is what no-one on CK wud recommend, they are well known for not making good quality products...
I would suggest you buy a solid product from a recommended manufacturer.
Like the Alpine MRV-F 545 for example...

Polk rates sensitivity of these speakers at 91dB @ 2.83 volts. That's not too bad for most full range speakers.
Pyle is not a tier 1 amp. Many of the Pyle products I have looked at, are often over rated and do not perform to meet specs. This amp is slightly over rated. However, if you look at how they market this amp, it says... it says "High Performance 2400 watt, 2 channel amplifier" Yeah... right? When pigs fly!!!
I'd have to agree with Victor here. Use a solid brand name amp to power them. An amp that delivers an honest 75-100 watts RMS x 2 @ 4 ohms, should do the job well.
FYI: This amp uses 2x20A fuses. When bridged MONO, that's about 300 RMS @ 4 0hms or ~75 watts RMS x 2 in stereo, is about what to expect.

Whew, I am glad that I asked you guys first. I just saw these amps and thought to myself, thats a good way to get lots of power to those speakers at a bargain price. But I am realizing alot of marketing car audio is painting a picture in someones mind about the supposed deliverance of a product, definetely not a field for the misinformed customer.

You have that one spot on sir!
To date, there are no FCC regulations for spec-ing car audio gear performance. Most of the top brands we recommend here at CK, meet or exceed specified ratings.
Also, CAE has recently allowed amp makers to rate their amp at 14.4 volts input. (CAE 2006 Compliant) However, very few vehicles can sustain 14.4 volts off the ALT/BAT for more than a few minutes.
FYI: Most vehicles will net out between 12.8 - 13.8 volts of steady output, after the BAT has equalized. This depends on the vehicle design and what the computer preset values dictate.
In Car Audio, amp power (Volts x amperes = Power = Watts) output is all related to power supplied to it. If the supply voltage drops, so will power output from the amp. There are a few well regulated power supply amps out there, (Like JL Audio) that provide a steady power output value as long as they get adequate voltage and amperage. That's one reason they are so good and pretty expensive.
In a nutshell, stick with well known brand names when shopping for car audio gear. In the long run, you'll be pleased with the performance.
