I'm thinking you meant Polk DB571's... If so then yea, that amp would be an excellent choice. For the Boston acoustics if you running something like the SC65 you will be good. Maybe fade your output to the rear a touch if you listen to it loud. Just because the SC65 is rated at 50watts at 4 ohm and the amp puts out 60 watts.
I'm not sure what kind of power the factory unit puts out. Might want to check before buying just to see if this is worth it. Sent from AutoGuide.com Free App
