Thread: Can this 4ch amp power my 4 lows and 4 highs?

yes you can power all your speakers using a 4 channel amp. I recommend that you install a "passive filter" or "passive crossover" of some kind to separate the frequencies going to the mids and tweeters (or 2.5" speakers).

A cheap way to do it is install a non-polarized capacitor of a correct value in series on the + line of the speaker if it doesn't have it already. Your other option is buy a more advanced passive filter or crossover.

Have you taken the speakers out yet? I can't really recommend a crossover point, but if I knew what the speakers looked like or maybe it has a cap installed already, then we could help you more. Or you could always just replace your speakers if it's too confusing with a "component set"

you need to know the impedance of the speakers first befor you figure out the crossover settings. I'm assuming you have the mach audio system right? This can be done but i'm not sure if it'll be worth it in the end. if you're going to bet a new amp I'd just go and get some new speakers. if money is tight now just get front speakers and an inexpensive sub. use the 4 chan amp for that and you'll probably have a great sounding system for relatively little $$$ and even less effort
