About the AudioControl EPICFOUR
From our tech experts at CEN
The AudioControl EPICFOUR is a Class D 4-channel car amplifier from the EPIC Series, delivering 800W RMS total — 4 x 200W at 2 ohms or 4 x 100W at 4 ohms. All four channels are bridgeable, giving 2 x 400W at 4 ohms. Its compact, thermally efficient chassis suits installs where space is limited.
Who it suits
The EPICFOUR is a good choice for anyone powering a full four-channel speaker system, including door and rear speakers, with solid output. The 2-ohm stability allows lower-impedance speaker loads without sacrificing power. For greater output across four channels, the AudioControl EPICBIGFOUR delivers 1400W RMS.
Our tech experts advise
Use 4 AWG cable for the power and ground runs and an 80A fuse at the battery; speaker terminals take 8 AWG. The variable Linkwitz-Riley high pass filter (50Hz to 500Hz, 12dB/octave) lets you protect tweeters and midrange drivers without a separate crossover. Line-level inputs accept 500mV to 12V RMS, which suits most head units. Fitting is priced per vehicle — ask us about car audio installation in Nottingham.
