AudioControl EPIC750 Review: Specifications, Installation and Comparisons
Quick summary: the buying decision
The EPIC750 is a 1-ohm-stable Class D monoblock from AudioControl's EPIC series: 300 W RMS at 4 ohm, 500 W RMS at 2 ohm and 750 W RMS at 1 ohm. It includes an ACR-E remote bass knob and EPIC Boost bass EQ, and it takes line-level inputs, so a factory head unit needs a line output converter.
AudioControl EPIC750: what it is
The AudioControl EPIC750 is a compact, 1-ohm stable Class D monoblock subwoofer amplifier from the EPIC series, delivering 300 W RMS at 4 ohm, 500 W RMS at 2 ohm and 750 W RMS at 1 ohm. An ACR-E remote bass knob is included.
EPIC monoblocks share 12 dB/octave Linkwitz-Riley low-pass (40 to 180 Hz) and subsonic (off to 50 Hz) filters, EPIC Boost (30 to 80 Hz, 0 to 12 dB), an Epicenter Link for AudioControl's The Epicenter bass restoration processor, smart auto-reset protection and an included ACR-E remote.
Key features
12 dB/octave Linkwitz-Riley variable low-pass filter (40 – 180 Hz) and variable subsonic filter (off to 50 Hz)
EPIC Boost variable-frequency bass boost: 30 – 80 Hz centre, 0 to 12 dB of gain
Built for The Epicenter bass restoration processor; Epicenter Link harness included
Smart auto-reset protection: over-current, over-voltage, under-voltage, DC-offset and over-temperature
4-gauge power and 8-gauge speaker terminals with hex-screw direct-wire connections
Specifications explained
Rated power at 14.4 V is 300 W at 4 ohm, 500 W at 2 ohm and 750 W at 1 ohm, and two amplifiers can be strapped for 1 x 1,500 W at 2 ohm. AudioControl quotes a frequency response of 10 Hz – 190 Hz and a signal-to-noise ratio of 92.2 dBA (ref. 300 W at 4 ohm).
Line-level inputs accept 500 mV – 12 V RMS.

Matching subwoofers and impedance
Decide the final impedance first: power rises as impedance falls, from 300 W at 4 ohm to 750 W at 1 ohm. At 2 ohm its 500 W suits one AudioControl EPICX10D4 or EPICX12D4 (500 W RMS each) with both voice coils in parallel; at 1 ohm its 750 W can drive two EPICX8D4s (about 375 W each).
Filters, EPIC Boost and remote
Set the low-pass filter to blend with the front speakers and use the subsonic filter to protect subwoofers, especially in ported boxes. EPIC Boost adds up to 12 dB around a chosen frequency between 30 and 80 Hz; every 3 dB of boost needs twice the power, so use it carefully. The included ACR-E remote adjusts bass level from the driver's seat.
Wiring, fusing and the electrical system
AudioControl specifies 4 AWG power and ground wire, 8 AWG speaker wire at the terminals and an 80 A fuse. Fit the main fuse close to the battery and keep the ground short and on bare metal. The amplifier measures 6.1 x 8.62 x 2.01 in (W x L x H).
