Will I need a DSP with this setup?

Mmats PA601.4cx in the fairing, PA690.4cx in the lids powered by a Stinger 700x4 or a Mmat MD4110.
PRV 6MR500-NDY in the lowers powered by a SD400.4s.
Want to add 8's to the bags at a later date so I haven't figured out that speaker and amp setup yet.

 

Imho you will need a dsp eventually to get full potential out of that system so you could just as well get it up front and start the learning curve.

 

Thanks. I'll put one in the budget.
