I am thinking about installing Boston Acoustic Rally speakers in my GSR and running them without an Amp (I am still using the stock head unit). Anyone else try this? I want to know if there is enough power to run the speakers loud and clear enough to be worth it?

 

I'm going to say no....It will work, but loud and clear...not really.

 

The BA speakers are very efficient. I will be happy with a volume a little louder than the stock system just with more range, better clarity and better sound.
