Space and fitment
Measure the boot or cabin space with the seats and boot floor in their normal positions, and allow room for the terminal and wiring. The SPK-V12 is 19.88 in wide, 15.75 in high and 16.02 in / 18.43 in deep (top / bottom). Secure it so it cannot move under braking: a loose enclosure is a safety hazard and causes rattles.
Amplifier matching and set-up
At 2 ohm, AudioControl's EPIC750 delivers 500 W RMS, a direct match for its 500 W rating; the A800.1 (600 W at 2 ohm) also works with the gain set carefully.
AudioControl recommends a subsonic filter at 26 Hz for this 34 Hz-tuned box; blend the low-pass with the front speakers by measurement.
