About the Option Audio SET-431

From our tech experts at CEN

The Option Audio Plug & Play kit for the VW Transporter and Ford Transit Custom is a complete sound system. It combines the OPTION DSP-4 amplifier, giving 2 x 60w plus 2 x 85w RMS with 5-channel DSP, the ROCK-3 20cm bandpass subwoofer at 130w RMS under the passenger seat, and FO-165 PRO front speakers.

Who it suits

Transporter and Transit Custom owners who want a clear step up in volume, clarity and bass from the factory radio, in one package. The DSP setup is loaded for your vehicle before delivery, so there is nothing to calibrate.

Our tech experts advise

Auto Sense switches the amplifier on from the radio signal, so no separate power feed is needed. Confirm the exact vehicle and year before ordering so the right setup is loaded. Installation is priced per vehicle, so get in touch with your make, model and year.

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: Which amplifier comes with this Transporter and Transit Custom kit?

A: The kit uses the OPTION DSP-4, a 4-channel amplifier with an integrated 5-channel DSP, supplied with a vehicle-specific setup already loaded.

Q: Where does the subwoofer fit?

A: The ROCK-3 bandpass subwoofer fits under the passenger seat.

Q: What is included in this kit?

A: The kit includes the OPTION DSP-4 amplifier with vehicle setup, the ROCK-3 passive bandpass subwoofer and the Option Audio FO-165 front speakers.
