Questions and answers

Is the 2550 watts RMS or peak?
Hifonics lists 2550 watts as maximum output. Treat it as a peak figure and expect lower continuous power, especially at higher impedance.
What subwoofers can it run?
It is a mono amp stable at 1 ohm, so it suits one or more subwoofers wired to a 1-ohm final load. Check your subs' combined impedance before wiring.
Does it need a wiring kit?
Yes. A high-power amp needs thick power and ground cable, a fuse, and RCA cables. Some bundles include a kit; confirm what is in the box before buying.
Can it power door speakers too?
No. It is a monoblock subwoofer amplifier. Door and component speakers need a separate multi-channel amp or head unit power.
Will it strain my car's electrical system?
Class D is more efficient than Class AB, but at high output it still draws heavy current. A stock electrical system may need a larger battery or alternator upgrade.
