DS18 X4 Ultra Compact Full Range Class D 4-Channel Car Amplifier 1320 Watts Max
Micro amps are a great power solution for an audio enthusiast that doesn't have a lot of room to spare for big bulky amps. In this case, you want to maximize your size to power ratio so you can get as much power you can with as little space as possible. DS18 now has the our newest micro amp, the X4. The X4 is about as large as a cell phone and packs a whopping punch. This tiny amp pushes out 70w x 4 @ 4 ohms, 140w x 4 @ 2 ohms, and 220w x 2 @ 4 ohms bridged. Now you need to sacrifice very little space for multiple power options that can power most mids, highs, and tweeters.
Highlights
- Small and compact amp putting out amazing power for its size.
