I just finished installing my new System. 600.4 amp Hybrid imagine 6.5 in the front and Hybrid 5x7 in the rear. Does anyone have any recomendations on gain, cross over and ohm swith settings. I currently have them crossed over at about 70hrtz and gains are set at 12 noon. Toggles are all for 4ohm and over.

Head unit was flashed for two amp four speaker system.

 

I run the Arc Moto 600.4 which is essentially same amp just smaller package. Crossover of 70 hertz sounds about right set switch to High. Ohm switch settings to 4ohm. I set my gains via DVM and gains are around 2 o'clock for my 4 ohm Focal speakers.

 

I notice you have band pass set to High at around 50 Hz. Why did you choose those settings, and how does the sound compare to the All pass setting? I'm confused as to which is best for my setup (RF T400x2ad, BT 7.1's).

 

The reason behind HIGH pass crossover settings is anything below setting ie 50Hz-80Hz(lower freqency range) would be cutoff thus protecting speakers from unwanted frequencies and possible damage. So you'd need to lookup specs to see low freq range for your speaker and make adjustment accordingly. My speakers specs say go down 60Hz but I beleive I have crossover set to more like 80Hz now. All pass or Full would allow full frequency range to pass through.

 

Full pass setting on the low sounds best to me. Great bass response (for a motorcycle) and allows clearly lower frequency sound to play.
