MDSP amplifiers
The MDSP range is designed for both OEM integration and custom builds. The MDSP 8/4A sits alongside the MDSP 6/4A and MDSP 8/6A in the lineup. Optional accessories include the MDSP Control remote, the MDSP-BT Bluetooth module, and the MDSP-TL TuneLink cable for linking two MDSP amplifiers.
DSP and sound quality
The MDSP 8/4A features high-resolution DSP with parametric EQ, fully adjustable crossovers, and per-channel input/output EQ for precise system-wide tuning. High-voltage speaker-level inputs, signal summing, and Morel's Speaker Load Assurance Module (SLAM) keep factory amplifiers stable during OEM integration.
Installer-focused features
Start/stop compatibility, automatic source switching, and TuneLink support for multi-amp tuning from a single device make installation straightforward. Bluetooth streaming and DRC compatibility give users direct control. The MDSP 8/4A is compact at 180 x 136 x 50mm, making it practical for tight install locations.

About the Morel MDSP 8/4A
From our tech experts at CEN
A 4-channel Class D amplifier with an 8-channel digital sound processor built in, so amplification and tuning arrive in one chassis, rated at 320w 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.
