2006 ultra
Currently running a pair of Focals in fairing.(Not sure which model as they have been there 7 yrs) Memphis audio in the lowers and a Arc XDI804 amp (80X4).
Thinking of upgrading to to moto 600.4 (150X4).
Thoughts or suggestions?

Thanks

 

Are you looking to change your sound? Make it louder? Add more bass? SQ?
Point being. Adding the 600.4 from the XDI804 is not going to change the sound much if the rest of the components are still in place. That said. It depends on the end goal. Anytime we drop $600 bucks for an amp the goal should be to enhance the system and make it sound better. Bottom line. Just adding a new amp from the same vendor to your system won't change the sound much.

 

If it's not loud enough the Arc Moto giving them twice the power should absolutely wake them up and provide you plenty of volume. On a lesser budget I'm liking the MMats MD4100 (4x100 at 4ohm).

 

Thanks for your suggestions. I will stay with what i got for now until I can spend a few more bucks changing speakers as well.
