About the Morel MDSP 6/4A

From our tech experts at CEN

A 4-channel amplifier, Class AB, with a digital sound processor built in, so amplification and tuning arrive in one chassis, rated at 100w RMS.

Who it suits

Drivers who want processed, properly tuned sound without finding space for a separate DSP and amplifier. In cars where space is tight, and in any vehicle keeping its factory head unit, this is the tidy answer.

Our tech experts advise

The processing is only worth what the tuning puts into it: measurements in the car, delays set for the driving seat, crossovers chosen for your drivers. That is the work, and we do it at our Beeston workshop. It also 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.
