Im going to be ussing 4 amps on 2 subs,which is why im interested in a maxxlink,so i can control all 4 with just one knob,plus it has a clipping indicator,might not be too accurate but doesnt hurt to have it.but thanks for your input,greatly appreciatedTbh, if you plan on using two amps and one dvc sub you can just gain match. It's best if you have a oscope but it's not that big of a deal. Just Google "two amps one sub" and you will get all kinds of interesting info. Is really not as hard as ppl think. If you are doing two amps two sub's just put them in sperate chambers. Or get a maxxlink if you want
