Good Things Come In Small Packages

Not many 4-channel amplifiers can honestly say that they are Class D amplifiers. Alpine's 2011 MRX-F30 can say just that. This 4-channel amplifier provides the strong and efficient performance that you would come to expect from a Class D amplifier. The amplifier features a highly efficient digital circuitry that lowers distortion and increases the clarity of the amplifier. Its CEA-2006 Compliance assures that the power output is accurate and true every single time, giving you optimal performance whether it is a short or long listening session. The multiple channel operations allows for multiple variations of installation making this amplifier extremely versatile. Its small chassis allows the amplifier to be mounted in any vehicle even if space is limited. If you need an amplifier than can carry enough power to amplify your devices but not take up too much space then the MRX-F30 is the perfect amplifier for any car audio enthusiast.

Great amp!!!

I have had this amp for a while now and it's great. I decided once to try another amp that was 25w/channel higher and this amp played cleaner and louder especially with the vocals. I would definitely recommend this amp to anyone.

Great Sound Gear

Just finish installing this amp to drive an alpine sps610 on the front and bridge channel 3-4 to drive a kenwood subwoofer speaker KFC-1012. Amazing sound clarity, quality and it really cocoons me w/ spine tingling sound sensation/reproduction in my cars little space.

Also coupled w/ fast Sonic Electronix technical support via email during the planning stage where the amp is in transit, i would say it is top notch.

Alpine Digital amp

If the PDX series is to dear, check out the MRX-F30 four channel digital amp. Rated at 50 watts x4 @ 4 ohm and 75 watts @ 2 ohm, alpine amps always come rated higher then the official rating. Expect your rating to be 75 watts @ 4 ohm and over 100 watts @ 2 ohm. This little amp is amazing in quality and output performance. Good quality speakers are a must, Polk Audio, JBL, Infinity, Energy are excellant choices.

I presently have the PDX-5 and the MRX-30 together as a garage audio system. The amps are running: JBL-5x7/6x8 components, Energy 6.5 components, 6x9 Polk Audio-3 way, 5.25 JBL coaxil, and two bose bookshelf speakers and run in parallel because they are 8 ohm vs 2 or 4 ohm. All 10 speakers rock. Alpine amps, an excellant choice. Good hunting. Sonic has been my main source of audio equipment and the best pricing overall.

Great mid-power amp

I wanted to beef up the wimpy stock amp in my 2011 F1-50. I combined with an Alpine PXE-H660 to keep stock controls and Head Unit. The sound is loud enough for me and very clean. It's also compact.
