Hi all, new to the Priuschat forum, Lots of good info here. Having fun with the car and am thinking it will work just fine. However the wife does not like the stereo and it does seem to lack something and it is the JBL 8 speaker. On monday we are having some new equipment installed and hoping it will fix. Replacing the front lower door speakers with either Hertz 6x9 or 6.5 in speaker. Install JBL 400/4 class d amp Install 10" non ported sub New amp to run new door speakers and bridge other side to run sub. Head unit to run other speakers as normal. Will report back on how it works.
