About the Zapco ST-6X DSP III
From our tech experts at CEN
A 6-channel amplifier from Zapco, Class AB, with DSP built in, rated at 100w RMS.
Who it suits
Drivers building a front stage that needs each channel doing a defined job. Zapco amplifiers are bought by people who care what the power figure actually means rather than what it says on the box.
Our tech experts advise
The on-board processing needs tuning in the vehicle to be worth anything. It needs a fused feed from the battery on the correct cable gauge. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: How do I choose the right amplifier for my speakers or subwoofer?
A: Match the amplifier's RMS output per channel to the RMS handling of your speakers or subwoofer at the same impedance. The Specification tab lists the power figures. If in doubt, contact CEN with your setup and we will recommend a match.
Q: What wiring do I need to install this amplifier?
A: You will need an amplifier wiring kit sized to the amplifier's power draw, typically including power and earth cable, a fuse, RCA leads and a remote wire. CEN stocks complete wiring kits, and the amplifier's fuse rating is the guide to the cable gauge required.
Q: What class of amplifier is this and does it matter?
A: Class D amplifiers are compact and efficient, ideal for subwoofers and modern installs. Class AB designs are traditionally favoured for outright sound quality on mid and high frequencies. The class is listed in the Specification tab where provided.
Q: Will an amplifier work with my factory head unit?
A: Yes, in most cases. If your head unit has no RCA outputs you will need a line output converter to feed the amplifier a clean signal. CEN stocks line output converters and can advise the right one for your vehicle.
Q: Can CEN install this amplifier?
A: Yes. CEN offers professional amplifier installation from our Nottingham premises, including secure mounting, wiring and setup. Contact us to book.
Q: Does the Zapco ST-6X DSP III have a built-in DSP?
A: Yes. It has an on-board, full function 8-channel digital signal processor with high-pass and low-pass filters, phase control, signal delay and parametric equalisation.
Q: Does the ST-6X DSP III have Bluetooth?
A: It has a Bluetooth port for an external aptX HD module, which is optional and not built in.
Q: Does the ST-6X DSP III have a digital input?
A: Yes. It has an optical digital input as well as analogue inputs with gain controls.
