About the Alpine SWG-844

From our tech experts at CEN

A 8 inch subwoofer, handling 120w RMS.

Who it suits

Drivers building a system where the bass does real work rather than filling in. This suits a sealed or ported enclosure sized to the driver, in a boot or a custom build.

Our tech experts advise

A subwoofer is only as good as its enclosure and the amplifier driving it: box volume and amplifier matching decide what you hear. We build enclosures and match amplification at our Beeston workshop. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs and what the work involves. See car audio installation.

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 size enclosure does this subwoofer need?

A: The recommended enclosure volume is listed in the Specification tab where the manufacturer provides it. As a rule, sealed enclosures give tighter, more accurate bass while ported enclosures deliver more output. Contact CEN if you would like a recommendation for your build.

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: Sealed or ported enclosure - which should I choose?

A: Sealed boxes are compact and produce tight, controlled bass suited to sound quality builds. Ported boxes are larger and produce more output at low frequencies, suited to those who want maximum impact. Either works well when built to the recommended volume.

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: What is the mounting depth of the SWG-844?

A: The SWG-844 needs 114mm of mounting depth and an installation diameter of 183mm.

Q: What impedance is the SWG-844?

A: It is a 4 ohm subwoofer rated at 120W RMS and 400W peak, so match it with an amplifier delivering around 120W RMS into 4 ohms.
