Well my 2008 Prius which I just purchased this week will be getting a new stereo in the next few weeks. I am going to start with the head unit only before later moving onto the speakers and sound deadening. After the head unit is installed I will later look to add my MB Quart ZA2-1600.4 4 channel amp and front and rear PPI P65C3 3 way components along with sound deadening of the doors. - Pioneer AVH4400NEX (got it off of a car audio forum for a steal) - Sirius XM module for radio above - Metra TYTO-01 - Metra 95-8240B - Metra 70-8114 - Metra Axxess ASWC-1
I just put a pioneer mvh390 in mine. I wired the radio direct from the harness. The only piece from the mounting kit i used was the faceplate trim. I also wired in a small kicker 4 channel amp and an audiopipe apmi 2000 and a pair of skar audio 8's. I got rid of all the jbl "premium " sound. I have been using the stock jbl tweeters as i havent got around to installing the rest of my components. Not impressed at all with the stock tweeters. It was a pain to find the pinout of the radio. Sound deadening is next on my list, and definitly has to help. Im running a regular 12v group 51 battery. The difference is amazing. I considered trying to use the stock head unit, but I am extremely happy i didnt. I used the trim piece to mount a switch so my son can watch dvds, and am in the process of wiring a switch and some diodes so i can turn on my aftermarket backup camera at will without turning on the reverse lights.
Also to note, i mounted my midrange amp under the passenger seat in place of the jbl amp. I ran new wire to the front speakers, but i personally felt the stock wire was ok for the rear speakers and tapped into that. The rear doors use a molex plug mounted on the chassis and the wires from the door plug into that. I didnt feel like messing with working around that.
The amp I have due to size will have to mount on the rear seat backs and I will run all new wiring as 200 wrms per the 4 channels I don't want to use the junk factory wiring.
Yeah headrest monitors will be coming after Christmas is over so my kids can watch movies while I drive.
