Description
The listing here is for the 5-Channel Class D Amplifier - 2 x 420W @ 4Ω - G4000.5D. The DS18 G4000.5D is a 5-channel Class D amplifier for powering door speakers, tweeters and a sub. Factory head units usually put out only a few watts per channel, so adding a real amp is what makes aftermarket speakers sound loud and clear with the windows down.
With 5 channels you can run front and rear speakers plus a subwoofer from one chassis. The compact footprint fits under the seat or behind the rear seat in most crew cab pickups.
Features
- 5 channels of Class D power
- Efficient design that is easy on your truck's electrical system
- Bridgeable for flexible layouts
- Protection against overheating and short circuits
- High- and low-pass crossovers to tune speakers and subs
