The wife and I were looking at an '09 Pri the other day. This was a Package 5. I noticed the audio quality was quite poor. Even adjusting the pseudo-equalizer didn't help much. I suspect the problem lies in the speakers used. Has anyone changed the factory spears on their Pri and got much bettery dynamic audio. If so, to what brand/part number?
I added B-Quiet Extreme and it sounded noticeably better, especially the bass. It should also block out more road noise as well but that wasn't noticeably to me.
Actually, I added B-Quiet Ultimate. I still have the half that I didn't use from my install.If you are interested, PM me for a very good deal. B-Quiet sound deadening materials - B-Quiet Ultimate - Better than Dynamat!! brownbread
You can try crutchfield and read the reviews of what people have posted. Crutchfield has very good customer support though their prices are a bit higher. You can find out the part number of the items you want and perhaps find it elsewhere.
