Customer Reviews

Reviewer: Dominic Wells

I bought two pairs of the sr65's a couple months ago. I have them hooked up to this t-600 4 channel amplifier. That is pushing 150 watts RMS of Rockford Fosgate Power to each individual speaker. They are totally bad ass. They play at very high levels. No distortion whatsoever. I could only imagine the pro series or maybe dream of the spz60. Boston Acoustics are no joke they are the best and I have heard them all. Any Fosgate, Kicker, alpine, focal, or anything out there are ok. Go with Boston the first time and you won't be disappointed.
