    I can't believe that people like this amp. It pushes 50 @ 14.4V. I mean is the top end of my charging system. Run the A/C and a few other accessories and I am below my 14.4V minimum to get any power out of these things. I can buy other products that are a FEW dollars more rated at a lower voltage and get more power than this amp. BOOOOO Alpine, affordability is cool but not at the point of having an under powered set of budget components.

    • Small footprint.
    • 50x4 and 14.4V - seriously...

  • Speaker compatability with Alpine MRP-F300

    Hi Guys, I have just purchased a 2011 Mazda 2 Hatch as a runaround work vehicle. But like my main vehicle I still appreciate some level of audio clarity. Unfortunately the Mazda 2 has shallow door cavities, so speaker selection is based on this and retaining the stock look to the vehicle. My search for components have lead me to: Front: Alpine SPS-600C (Component) Rear: Alpine SPS-600 (Coaxial) Sub: Alpine SWE-1500 (powered compact) I will be running off the stock 50W head unit and have purchased a 24pin aftermarket connector to eliminate the cutting of the orginal audio harness. My first question is ... which of the following amps would be suitable the run the above components: Alpine MRP-F300 Alpine MRP-F600 The second question would be how do I connect the above sub into the system ?

  • needed speakers . (in terms of RMS)

    What are the specs of the speakers needed. (in terms of RMS)

    Answered by Bobby 2009-09-09:

    The MRP-F300 sends 50 watts through its four channels at 4 ohms, and 75 watts at 2 ohms. The outputs can also be bridged, and in that mode the MRP-F300 will send 150 watts to a pair of subwoofers at 4 ohms. So, any full range speakers that are compatible with these frequencies (RMS wattage: 300)can be used.

    Answered by clockwatcher 2010-01-16:

    I run 2-5by 7's w/a 65 watt rms rating in front and 2 MTX truck wedge enclosed speakers w/8 in. woofers and a horn tweeter in each they are 15-20 yrs, old but I would guess rms is 90 to 95 watts ea.My F-300 can work them hard and loud with no clipping.Strong,Clean 300 watts. When in doubt Bobby gave a good answer.
