I searched like crazy on this site some other car audio sites yahoo!, etc. but i can't seem to find the answer. So I figured some of you car audio people could help me out...

can I use the high input and the low input of my cheesy amp at the same time, like my h/u and sound card, or is it better to hook the sound card and h/u into a y-cable and put them both into the low input of my amp...

thanks for any help! please feel free to tell me I am stupid and should be something completly different...
