Which Alpine subwoofer should I choose?
For a bass upgrade without a separate amplifier, the SWE-815 (8-inch, 100W RMS) and SWD-355 (12-inch, 150W RMS) are self-contained powered boxes connecting directly to a head unit via RCA or speaker-level input. The PWE-S8 (120W RMS) and PWE-V80 (160W peak) are slim powered units that disappear under a seat. If you are building your own system, the S Series drivers handle 300W RMS at 8 inches and 600W RMS at 10 and 12 inches with carbon fibre and polypropylene cones and dual voice coil options; the Type-G range covers 8, 10 and 12-inch sizes at 120–250W RMS in a single 4 ohm configuration. The R Series RS-W10 shallow-mount drivers have an 81mm mounting depth for space-limited installs.
Van and camper owners can choose from vehicle-specific enclosures: the SWC-D84T6 for the VW Transporter T6, the SWC-W84TRA7 for the Ford Transit, and the SWC-D84S or SWC-D84DU for the Fiat Ducato, all fitting into existing spaces without cutting bodywork — though a compatible amplifier is required separately for each. The SS-SB10 preloaded sealed enclosure suits those who want a ready-built box to pair with their own amplifier.
Alpine Subwoofers FAQs
Q: What is the difference between the SWE-815 and SWD-355 powered subwoofer boxes?
A: The SWE-815 is an 8-inch amplified box rated at 100W RMS, while the SWD-355 is a 12-inch unit with 150W RMS output; both include a wired remote control and accept RCA and speaker-level inputs.
Q: Do the Alpine vehicle-specific enclosures such as the SWC-D84T6 and SWC-W84TRA7 include an amplifier?
A: No — the SWC-D84T6 (VW Transporter T6) and SWC-W84TRA7 (Ford Transit) require a separate compatible amplifier; the SWC-D84S for the Fiat Ducato also needs a separate amp but does include a plug-and-play ISO wiring kit.
Q: What is the difference between the Alpine S Series and Type-G subwoofer drivers?
A: The S Series (S2) drivers handle 300W RMS at 8 inches and 600W RMS at 10 and 12 inches with a carbon fibre and polypropylene cone and dual voice coil options; the Type-G range handles up to 120–250W RMS in a single 4 ohm configuration across the same three sizes.
Q: Can CEN fit an Alpine subwoofer at their Nottingham workshop?
A: Yes — CEN has a fitting workshop in Beeston, Nottingham, where the team can install Alpine subwoofers, including powered boxes, component drivers with an enclosure, and vehicle-specific underseat solutions.
Q: Which amplifiers does the Alpine RUX-KNOB2 remote work with?
A: The RUX-KNOB2 is compatible with Alpine X, R, S, V and PDX series amplifiers and connects via the supplied 5m RJ-14 cable for neat dashboard or under-dash mounting.
