Morel Kinetic 12.4 12" Car Subwoofer 4 Ohm 350W RMS

Quick answer

The Morel Kinetic 12.4 is a 12 inch single 4 ohm car subwoofer, model KS124, rated at 350W RMS and 700W peak.

Morel publishes both a sealed and a ported box, so it suits a tidy boot build or a louder vented setup.

Problems it solves

• Bass that rolls off early in a sealed box. Morel quotes F3 at 41 Hz in 34 litres.
• Wanting more output for the same power. The ported box is tuned to 27 Hz.
• Heavy cable that will not fit small terminals. Spring posts take 10 AWG wire.

What is in the box

Install notes

Use the port size Morel lists if you build the vented box, since the tune depends on it. Seal every joint and run 10 AWG cable to the spring posts.
