About the Zapco HB 810 II 8AD
From our tech experts at CEN
The Zapco HB 810 II 8AD is a 10-channel DSP amplifier from the Harmony HB II series, combining a 31-band EQ with an integrated 8-channel amplifier — four Class A/B and four Class D channels — in a 190 x 166 x 45.5mm unit. It accepts 8-channel high-level and 2-channel RCA inputs, outputs 10-channel RCA, and includes Bluetooth 5.1.
Who it suits
This suits enthusiasts building a multi-way car audio system who need DSP tuning and multi-channel amplification in a single unit. The Class D channels bridge to 2 x 300W at 4 ohms, making them well suited to subwoofer duty. Those preferring an all Class A/B solution should consider the Zapco HB 410 II 8A.
Our tech experts advise
At 190 x 166 x 45.5mm, check your available boot or under-seat space before ordering. The 8-channel high-level input connects directly to OEM speaker outputs without a line output converter. The optional HB DSP II-R remote adds dash-mounted volume and preset control. Fitting cost varies by vehicle — visit our Nottingham installation page for details.

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: 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: How much power does the Zapco HB 810 II 8AD have?
A: Its integrated amplifier delivers up to 4 x 35 watts (Class AB) plus 4 x 100 watts (Class D) at 4 ohms, or 4 x 50 watts (Class AB) plus 4 x 150 watts (Class D) at 2 ohms. The Class D channels can be bridged to 2 x 300 watts at 4 ohms.
Q: Can the HB 810 II 8AD connect to a factory head unit?
A: Yes. It is plug and play ready with 8 channels of high-level inputs, plus 2-channel RCA inputs and 10 RCA outputs.
Q: Can I set up the HB 810 II 8AD from my phone?
A: Yes. With Bluetooth and the dedicated app you can control and set up the system from your smartphone, and PC DSP tools are also available.
