I would disable the crossovers on the headunit and play with the crossovers on the amp. I wouldn't trust what the numbers on the amp say though. I would play around while listening to music and see if you can get some improvement.
I tried this tonight. There wasn't a way to "disable" per say, the crossover so I just set it to the default setting. I left the amps crossovers as is. Now at volumes above 20 my comps amp turns off with a "CUR" error. The manual says it is a current issue. Too much current is being fed to the amp. This happens only to the comp amp. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
