Have a tune question. Just wanna make sure I'm getting everything out of the wife's bike. Finally finished install of mpx 6.5 and mpx 690 in lids powered by fosgate 400x4. I'm looking into bigger amp. What should frequency and eq be on? Thanks

 

What head unit are you using?

When i had the 690s i ran them between 80-100Hz. It's hard to tell exactly with the dial on the amp. Just start with the kind of music she will be listening to turned up to max listening volume, isolate the front from the rear, turn the hp high around 500 and slowly turn it down until either you are happy or the speaker is unhappy, and then repeat for the rear.
