About the Morel MPD 5.550
From our tech experts at CEN
A 5-channel amplifier, Class D, rated at 550w RMS.
Who it suits
Drivers who have upgraded their speakers and found the head unit cannot drive them properly.
Our tech experts advise
Matching matters more than headline watts, and the gains want setting with a meter rather than by ear. 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.
