i just finished installing these speakers to my kenwood excelon 889 headunit, and also a 350 watt kenwood excelon 2 channel amp, as far as "tuning" goes in the sound department im not as proficient as i am in mechanics. Any one have advice? Sounds great already but, using my internal cross over of my head unit is getting a little annoying, anyway i can vary how much power goes into my speakers from my external amp?

 

Turn the gains all the way down on the amp. Turn the HU all the way up and then tune from there. Adjusting gains up and the the rest of the tuning in such a way that its pleasing to your ears... since your the one that has to listen to it.

Once your speakers start to distort back the gain down a little bit so they won't distort and go from there. It takes a little while but once your done you shouldn't have to worry about your speakers getting damaged... from the sound its trying to reproduce anyway
