So our list starts with Rockford Fosgate R500X1D, which is ideal for pairing with Alpine Type R 12-inch subwoofers. While testing the R500X1D amp in the lab, I found that the size of the amp is compact and has a versatile design to bass up your car audio system and deliver high-quality audio.

The Rockford Fosgate R500X1D is mono type subwoofer amplifier and capable of driving the Alpine Type R 12 with ease as it has a power rating of 500 watts RMS at 2 ohms (300 watts RMS x 1 at 4 ohms) and features MOSFET power supply.

The R500X1D is from the Prime series and has Class-D circuit topology ensuring maximum power efficiency, so it means loud and clear bass can be easily enjoyed without straining the vehicle’s electrical system. On your car, you can install the R500X1D amp in a variety of locations due to its compact size, while durability and reliability are guaranteed by its robust construction. Do you have Rockford Subwoofer?

While testing, I feel like the Rockford Fosgate R500X1D has an elegant black color coating, and its body design is much more compact, great for small cars. The power ratings of Rockford Fosgate R500X1D are verified by Consumer Electronics Association and approved as CEA-2006 compliant amplifier, so no worries at all.

The R500X1D features a built-in variable low-pass filter (50-250 Hz, 12 dB/octave) and a variable bass boost (0-12 dB at 45 Hz), which makes it better for you to customize the sound as you wish for. As Rockford Fosgate R500X1D is a powerful amp so the company has installed a cast aluminum heatsink, so while powering Alpine type R12 sub, if the amp even gets hot, then its heatsink functionality will maintain temperature and remain amp cool.

The connectivity of R500X1D also includes preamp and speaker-level inputs and preamp outputs. With the help of a Phase switch on the R500X1D amp, you can invert the polarity of the output signal to get super duper sound quality and feel your bass rockin. The frequency response of the R500X1D amp is 20-250 Hz which is good.

You can also utilize the remote Punch Level Control feature of Rockford Fosgate R500X1D to control the amount of bass sent to your alpine subwoofer from the remote. Sadly you will not find no on-board fuses on the R500X1D amp, so maybe the need for a 50-amp in-line fuse will be required in situations when you were installing multiple amps in the system.

So overall the under $300 range, the Rockford Fosgate R500X1D is the best amp for Alpine type R12 that features advanced protection circuitry, high-quality construction, compact size, high power output, and advanced features that make it excellent for any subwoofer.
