Authorized dealer · Car Audio Bargain
Monoblock amplifiers put all of their power into a single channel, which makes them the standard choice for driving subwoofers. Car Audio Bargain, an authorized dealer, carries mono sub amps from Sundown Audio, Crossfire and Audio Apex, from the Crossfire C3-500D and C5-800D up to Sundown SIA amps, the Audio Apex CAB-45v2 and Crossfire BMF competition models.
Total the RMS rating of every sub in the enclosure, then wire the voice coils to a final load the amp is rated to handle. Dual voice coil drivers give more choices: two dual 4 ohm subs, for example, can be wired to either 1 ohm or 4 ohm. Pick the amp whose RMS output at that final load comes close to the subs' combined rating.
A single sub in a daily driver rarely needs more than one of the monoblock amplifiers under 1,500W. Multi-sub walls and SPL vehicles move up to the 4,500W+ range, where the charging system matters as much as the amp. Leaving modest headroom is fine; running an amp flat out with the gain cranked is not.
Bass amps draw serious current on every note, so power and ground wire should be sized for the draw and the length of the run. Smaller builds are covered by a complete amp wiring kit, while bigger monoblock amplifiers often need 1/0 AWG power wire with a fuse close to the battery. Set the low-pass filter and subsonic filter to suit the enclosure, then set gain with test tones so the amp stays out of clipping. For speaker amps and more options, return to all amplifiers.
