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

    I'm in the process of building my carPC and need to make a decision on how to get sound to the speakers. There are four 5"x7" speakers and four 2.5" tweeters in my car. The tweeters were powered by an amp in the stock headunit. The 4 bigger speakers are powered by 2 amps in the trunk, and I can tap into them with the right harness. However, since I will need to be installing an amp for the tweeters anyway, I am considering getting a new amp to power all the speakers.

    Will one 4-channel amp be able to power all 8 speakers (the 4 mid speakers and the 4 tweeters), or will I still need to install more than 1 amp to power everything? I am looking at the Profile AP1040.

    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"

    yeah crossover is defidently what you want. dont bother making one, you should be able to find a crossover very easily for relatively cheap. My component speakers i got came with a crossover

    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

    This is exactly the same product I purchased and I have also 4 speakers and 4 tweeters and the way I'm thinking to hook up the tweeters is by placing a High Pass Crossover filter, since this unit comes with "Tri Way Crossover".
