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.

Frequently Asked Questions

What is the ideal wattage for an amp to power the Alpine Type R 12 sub?

The wattage required for powering a subwoofer like Alpine Type R 12 firstly depends on bass preferences. However, the expert recommendation says at least 1000 watts of RMS power you have to aim from the Amplifier. Some people think that increasing power, like up to 1500 watts RMS, will increase better sound quality, but this is only sometimes true because sometimes it may damage your subwoofer.

Can I bridge two channels of a multi-channel amp to power the Alpine Type R 12?

Yes! And experts say this is a recommended way to get the most out of the Alpine Type R 12 sub. Simply you have to bridge two channels of an amp by connecting the positive and negative terminals of the Alpine subwoofer to the Amplifier + and - terminals of one channel amp and repeat this process for another channel amp so a single 4-ohm load will be created which the Amplifier can drive. After bridging the channels, go to your amp and find Gain Control, which you must utilize to get the desired output level. You can also adjust the crossover frequency to ensure the Alpine Type R12 sub only plays the required frequencies.

Do I consider amplifier size for Alpine Type R12?

For homeowners, the amplifier size doesn’t matter, but car owners may consider amp size always. Car Space availability must be checked, and an excellent placement for the Amplifier must be where there is excellent air circulation so that for long hours of usage, it will not overheat. Find an Amplifier with a heavyweight heat sink like Kicker 46CXA8001 suitable amp for use in the car.
