Frequently Asked Questions
Q: Do I need an amplifier for this subwoofer?
A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.
Q: What does RMS power mean?
A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.
Q: Can CEN build or supply an enclosure and fit everything?
A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.
Q: Does the PULSE-8BRA need a separate amplifier?
A: No. It is an active subwoofer with a built-in 350W RMS amplifier.
Q: Can the PULSE-8BRA connect to a factory radio without RCA outputs?
A: Yes. It has a high-level input supplied with a Molex to loose ends cable, plus remote auto turn-on when using the high-level input.
Q: Does the PULSE-8BRA come with a bass remote?
A: Yes. A level remote control is included, with 2 screws and an Allen key for mounting.
