Bass it up
Got a nice sub? Give it some serious power by JBL. The GTX500 mono subwoofer amp will send up to 500 watts RMS to your sub, filling your car or truck with powerful bass. A low-pass crossover and bass boost allow you to dial in the best tone for your subwoofer, enclosure, and vehicle.
Smart amp
The GTX500 turns itself on when it senses an incoming signal, so running a remote turn-on lead all the way from your car stereo isn't necessary. The amp also turns itself off about five minutes after the signal stops, so there's no danger of running your battery down. You can switch this feature off if you'd rather use a remote lead.
- Mono subwoofer amplifier
- 350 watts RMS x 1 at 4 ohms (500 watts RMS x 1 at 2 ohms)
- Class D amp technology
- Frequency response: 20-200 Hz
- Variable low-pass filter (45-300 Hz, 12 dB/octave)
- Variable bass boost (0-12 dB at 45 Hz)
- Signal-sensing turn-on
- Preamp and speaker-level inputs (adapters included)
- Fuse rating: 25A x 2
- 8-gauge power and ground leads recommended — wiring and hardware not included with amplifier
- 8-3/8"W x 2-9/16"H x 9-11/16"D
