5 Star Rating Richard From Alabama
Great speakers for the price, not a whole lot of bass with these but they are great, really loud and only distort when I have the bass up and volume on about 35/40, so really that's great coming from a Jensen 7In flip out. Mids and highs are great, I have 4 all the way around in my single cab 1988 Silverado and they fit perfectly.

5 Star Rating Derek From Saint Jo,MO
Great speaker got them about 6 months ago just put them in.It took about 3 days for them to fully break in,but now i can turn my pioneer head unit up all the way and they do not distort.They even have enough bass to vibrate my side mirrors.
