Product Description
Alpine designed this amp to run a 3-way active system. Channel 1/2 can send a couple tweeters up to 75 watts RMS each and features a high-frequency high-pass filter necessary for safe tweeter operation. Channel 3/4 can send a pair of midrange drivers 75 watts RMS each and features a band-pass filter that keeps extreme highs and lows away from the midrange speakers. Channel 5/6 is for subwoofers, low-pass filter only, and can power two subs with up to 250 watts RMS each, or one sub with 500 watts.
