Model: MV400/4i

4-Channel Class D Full-Range Marine Amplifier with Integrated DSP, 100 W x 4 @ 2 ohms / 75 W x 4 @ 4 ohms - 14.4V

Engineered to deliver reference-grade audio performance in marine environments, every MVi amplifier unites our cutting-edge NexD2â„¢ switching amplifier technology with an integrated, full-featured digital signal processor.

Outfitted with our second-generation NexD2â„¢ technology, the MV400/4i produces up to 75 watts per channel into 4 ohms, or 100 watts into 2 ohms. It can also be bridged into 4 ohms, generating up to 200 W x 2.

The NexD2â„¢ full-range technology in this amplifier is DSP-controlled and features a reduced loop area design utilizing DirectFETâ„¢ outputs for outstanding fidelity, very low noise and exceptional efficiency. Housed in a compact, cast alloy chassis with marine-grade powder coat finish, the MV400/4i is outfitted with corrosion-resistant hardware and connectors.

Instead of traditional control knobs and switches, all amplifier adjustments and DSP functionality are configured via a compatible external device (PC, Tablet or Smartphone), with the appropriate JL Audio TüN® Software application installed.

USA Limited Warranty: Two (2) years from the original date of purchase.

Heavy-Duty 4 AWG Cable With Flexible Insulation
Size: 10ft, Color: 4awg
I am satisfied with this 4 AWG cable. The insulation coating is soft, and the cable itself is very pliable, making it easy to bend and route into the configuration needed for installation. Despite the flexibility, it still feels like a heavy-duty cable designed to handle demanding applications. I am using this cable to provide the necessary amperage to start the generator on my trailer, and it performs as expected. I also like that the wire gauge and cable properties are clearly printed along the side of the insulation, making identification easy during installation or future maintenance. The cable arrived in good condition with no obvious odor from the insulation or packaging. Overall, this appears to be a quality heavy-duty cable that is flexible, easy to work with, and suitable for high-current applications.

True copper battery cables that are high quality
Size: 10ft, Color: 4awg
I love having heavy duty cable on hand for my cars. It's so nice to be able to make your own starter and alternator cables when restoring cars. These cables are 100% copper, not CCA (copper clad aluminum) like many others are. Copper is far superior for conductivity and handling higher loads. The rubber on the cable is thick and yet very flexible..it's clearly marked and seems very durable. I like to use a hydraulic crimping tool and then add marine grade heat shrink tubing with the adhesive inside of it to keep it as weatherproof as possible.
