Warhorse 3600W Monoblock Class D Subwoofer Amplifier (49WXA36001)
The Warhorse was engineered entirely in-house by Kicker R&D for ultra-high SPL applications, and tested thoroughly for extreme performance and reliability.
Fortified to Go Hard
This full-bridge, 1-ohm stable amplifier features dual 1/0 power and ground connections, 4 AWG speaker terminals, dual 8 AWG remote terminals, and quad microprocessor-controlled fans for fast, quiet cooling on demand. Tiffany-style RCA connectors are fitted as standard.
Engage Competition Mode
Competition Mode fixes input sensitivity at 4 volts and locks the gain potentiometer, making it straightforward to gain-match across multiple amplifiers.
Real-Time Status Tools
Included is a heavy-duty, magnetic-mount diagnostic tool displaying battery voltage, thermal protection status, power-supply protection, and speaker current overload in real time. A premium remote bass-level control with magnetic mount is also included, connected via a 6 m (19.75 ft) RJ45 cable.
Compatible
Kicker FIT+™ (Fail-safe Integration Technology) differential inputs and a 125mV–40V RCA input range ensure compatibility with most factory and aftermarket source units. The amplifier is also start/stop compliant. If you need a mono subwoofer amp at a lower power level, Kicker also offer the Kicker 46CXA800.1 1-channel mono amplifier up to 800W RMS.

About the Kicker 49WXA36001
From our tech experts at CEN
A monoblock amplifier for subwoofer duty, rated at 3600w RMS. Everything it makes goes to the bass.
Who it suits
Anyone adding a subwoofer that needs real power behind it rather than a compact powered unit.
Our tech experts advise
Published power figures mean little until the amplifier is matched to the speakers and the gains are set with a meter rather than by ear. It needs a fused feed from the battery on the correct cable gauge, the part we most often see done badly. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: How do I choose the right amplifier for my speakers or subwoofer?
A: Match the amplifier's RMS output per channel to the RMS handling of your speakers or subwoofer at the same impedance. The Specification tab lists the power figures. If in doubt, contact CEN with your setup and we will recommend a match.
Q: What wiring do I need to install this amplifier?
A: You will need an amplifier wiring kit sized to the amplifier's power draw, typically including power and earth cable, a fuse, RCA leads and a remote wire. CEN stocks complete wiring kits, and the amplifier's fuse rating is the guide to the cable gauge required.
Q: What class of amplifier is this and does it matter?
A: Class D amplifiers are compact and efficient, ideal for subwoofers and modern installs. Class AB designs are traditionally favoured for outright sound quality on mid and high frequencies. The class is listed in the Specification tab where provided.
Q: Will an amplifier work with my factory head unit?
A: Yes, in most cases. If your head unit has no RCA outputs you will need a line output converter to feed the amplifier a clean signal. CEN stocks line output converters and can advise the right one for your vehicle.
Q: Can CEN install this amplifier?
A: Yes. CEN offers professional amplifier installation from our Nottingham premises, including secure mounting, wiring and setup. Contact us to book.
Q: How much power does the Kicker 49WXA36001 produce?
A: It delivers 3600W RMS at 1 ohm, 2500W RMS at 2 ohms and 1400W RMS at 4 ohms, all at 14.4V. Dynamic power is 5000W.
Q: Does the 49WXA36001 come with a bass remote?
A: Yes. A premium remote bass-level control with a magnetic mount and a 6 m RJ45 cable is included, along with a magnetic-mount diagnostic tool.
Q: What is Competition Mode on the 49WXA36001?
A: Competition Mode sets the input sensitivity to 4 volts and locks out the gain potentiometer, which makes gain-matching across multiple amplifiers easier and fixes the crossover setting.
