Had a recent amp issue which led to upgrading to the sp4.900 hertz. Still waiting on that to arrive. Meanwhile, already have the HDHU14 radio, Hertz SX165 in fairing, Mmats PA601 in lowers, Hertz SX690 in bags and just put the Hertz SV165 in the tour pack. Can’t wait to hear it play soon. Should be plenty loud around 80mph.

 

I'm going back and forth on putting a set of Mmats 601px's in the lowers to match the fairing or just 601s to add more to the lower-mid range... How are you liking the 601s? Do you get good thump from them in the lowers?

 

I have had both Mmats in the lowers, the CX was better for my ears.
