So finally going to pull the HK head unit and installing a Sony MEX-M70BT.
I had Kappa 62.11 in the faring and the lowers. Replaced the blown faring Kappas with the AD Design CX62. The amp is a Acoustik RZ4-2000D.

My question is should I replace the Kappas in the lowers with something else?

 

Mmats 601.8

 

yup! This is a killer combo.

Only my think to consider is how you are using the crossover. I believe that amp does not have an adjustable crossover so if you leave it at the static setting you may need to keep the gain down. Other option as a second set of AD's. Last option, keep what you got.

 

Could I run the Mmats without horns?

 

Yes. If you are going to put them in the fairing you would use a horn with them, but if you are putting them in lowers I believe you can go without a horn.

 

lol. they will make your engine guard shake

 

Going with MMats in the lowers and AD DesignCX62. Thanks for the help.

 

You need an amplifier with an adjustable HPF to run any pro audio speaker. I'm pretty sure the amp you listed just has a switch and a static position for HPF. I'd advise against running the MMats if that's how the amp works.

 

No adjustments on amp other than gain. I could push my budget and get a new amp. Want to stay below $500.00 or wait till I can add more $

 

shoot me an email. I got an idea.
