Description

Alpine

Authorized dealer

The V12 AccuClass-D amps deliver unimaginable amounts of power for pushing subwoofers past the levels accepted by most neighborhoods. They're the only amps on the market with a true digital design. This keeps the signal more pure, and makes them extremely efficient! Another huge benefit is their use of digital signal processing which provides time correction and other sophisticated controls. The digital signal processing and other controls are all monitored through Alpine's 'Digital Control Center' which is located under the top mounted access panel (see other pictures). If one amp is not enough, Alpine also has an Amplifier Link unit that lets you connect up to eight of these powerhouses and control them from a selected Alpine head unit.

Alpine MRD 501 Class D Monoblock Amp

This is a superb powerfull quality class D Digital subwoofer amp, i run 2x 12 Alpine 1222D Type R's parrallel @ 2ohms, the amp @2ohms is Pushing 600W Rms easilly, conservatively rated at 550w Rms @2ohm with a peak of well over 1000w Rms, Very deep and powerfull bass when set up correctly, I use the Amplink ( Kce 510 amplink box cables needed ) with the Alpine 9835R and can control most functions of the amp from the drivers seat with my awsome stereo like P Eq, bass boost, subsonic filter, t correction, etc etc, shows voltage, temperature, amps current usage etc on the 9835R display, so you can keep an eye on your car battery's voltage. You can control upto 8 amps linked together with Alpine Y cables from the 9835R. Very efficient amp runs at around 30 degrees but have seen 40+ when playing loud for extensive periods. The bass is so powerfull it makes my roof flex and vibrates everything in the car. The amp itself has a digital display and control panel, which show the Volts Temp current etc looks relly nice and very usefull. All in all if you looking for a subwoofer amp you cant go wrong with the Mrd 501. Superb
