I need help purchasing an Amp.

Recently I bought a pair of Polk Audio DXI 460P Speakers for my doors and a pair of Kenwood KFC-6993PS speakers for my back. The door speakers can handle 50 Watts RMS and the back speakers can handle 120 Watts RMS. I am looking for an Amplifier to power them.

I have come up with a few different Amps that I am considering.

1. (My first choice) An MB Quart Discus amp that is going for 83.47 on Amazon.
Amazon.com: MB Quart Discus DSC450 200 Watt A/B Class 4-Channel…
I have heard MB Quart makes good Amplifiers and this seems to suit my needs, but I have also heard some bad things about Mb Quart as well.

2. A Refurbished Rockford Fosgate R300-4 that is going for 114.95. It can produce 50 watts RMS to four channels at 4 ohms.
Amazon.com: Rockford Fosgate Prime R300-4 300 Watt Multi Channel Amplifier: Electronics

3. A Kicker 08ZX200.4 amp for 99.99 with free shipping on Crutchfield. It can only produce 35 watts RMS.
Kicker 08ZX200.4 4-channel car amplifier — 35 watts RMS x 4 at Crutchfield.com

4. (My absolute last choice due to price.) An Alpine MRP-F300. It can do 50 watts to all four channels but will also cost me the most money.

I am almost broke from this audio adventure and the Amp is the last thing I am buying for now. Out of those can you please tell me which is the best and worth the money?

get the MB quart it's the best for the price of the ones you listed

I was thinking the same thing. It has all of the features and power I want and also is at a price well within my price point.

The Alpine will sound the best, but since your on a budget the MB.

The Kicker is in my range too but is also a bit more money for less power. Are you still reccomending the MB over it also?

I had a ZX200.4 that benched at 241@4 bridged. If I remember right it was about 41x4@4.

Whats your budget?

My budget is about $100. I have eliminated the Alpine and the Rockford and am only now looking at the Kicker and the MB. They are both 4 channel which is what I need.

personally I'd take the MB over the Kicker. You get more power and I know some of the discus amps were rated at 12v

Im just kind of worried though. I have heard some shady things about the Mb Quart Amp and read a few bad reviews. I have seen nothing wrong with the Kicker. The only thing I am worried about with the kicker is if it will put enough power to the speakers to be worth buying.

The Kicker is under rated. It should do somewhere around 240@4 bridged which is roughly 41x4@4. You wont hear an audible difference in output between the Kicker and the MB Quart.

And the kicker seems to have a slightly better warranty/customer support base...better quality...and a somewhat better rating of overall AQ. I am willing to pay the extra seventeen dollars for the Kicker if it is truly a better Amp. MB Quart seems to have tanked since it has been taken over by Maxxsonics.
