Sony XS-162ES Mobile ES™ Series 6-1/2" component car speaker system digital rear view mirror Alpine's engineers built the tweeter

Alpine's engineers built the tweeter to produce smooth high notes and paired them with a durable polypropylene woofer

It puts out six channels of 50 watts RMS each to speakers with 4- to 2-ohm impedances — so it'll work equally well with factory and aftermarket speakers — plus two channels that can each produce 150 watts RMS at 4 ohms and 300 watts RMS at 2 ohms

Power @ 4Ω: 500W RMS
