ST-750D
Mono Class D Compact Amplifier
The ST-III amps were the first to get the new Studio brushed aluminum finned chassis, with the standard measurements for all models of 16 cm (W) and 5.8 cm (H). With the new ST-D Compact Series we've decreased these dimensions to 12.4 cm (W) and 5 (W), further reducing an already compact chassis.
The small size does not mean reduced performance or control possibilities. Also in the ST-D Compact Series you will have the possibility to use RCA or Speaker Level inputs, variable input gain control, variable electronic crossover and bass boost control.
With the new ST-D amps you will no longer have the problem of combining sound quality, power and available space.

FAQs
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.
