Our take on the XR500.1D Ultra Compact 1-Channel Class D Amplifier

The XR500.1D is a mono Class D car amplifier rated for a single subwoofer channel, with an on-board bass control for tuning low-end output. Its compact chassis is aimed at space-limited installs where a full-size amp won't fit. The only price seen in its recent history is $99.99, so there is no lower or higher point to compare against yet.

Pros
  • Class D design runs cooler and draws less current than Class AB
  • Small footprint fits under seats and in tight cavities
  • Built-in bass control saves adding a separate processor
  • Single-channel layout keeps wiring simple for one sub
Cons
  • One channel only, so it cannot drive front or rear speakers
  • No published power figures here to size it against a sub
  • Bass control adds a tuning step for beginners
  • Budget mono amps often skimp on heatsink size under long loads

Questions and answers

Is the XR500.1D worth it at $99.99?
At $99.99 it is an entry-level mono amp, and that is the only price recorded since November 1, 2026. It makes sense if you need a small, cheap amp for one sub and do not need big power.
What subwoofer can this amp drive?
It is a single-channel Class D amp, so it drives one sub or a pair wired to a final mono load. Match the sub's impedance and RMS rating to the amp's rated output, which is not listed here.
Does it have a bass knob?
Yes, it has bass control built in. That lets you adjust low-frequency output from the amp rather than adding an external processor.
Will it fit under a car seat?
It is sold as ultra compact, so it is a candidate for under-seat or behind-trim mounting. Check the exact dimensions against your space before buying.
Is a Class D amp good for bass?
Yes. Class D is common for subwoofer amps because it is efficient and runs cooler, which suits the long, heavy draw of bass duty.
When is the price lowest?
The only price on record is $99.99, dated November 1, 2026. There is no cheaper point in its history to wait for.
