Below is a post I just made at a lexus forum...I'm hoping that someone here will be able to help.
It's been a long time since I've been on this site! I've stayed away from car audio for a couple years...ever since my entire car was stolen with my ~5000.00 in audio...needless to say...I shed more than a few tears...
So I just got a good deal on a Pioneer AVH-P4200DVD that I would like to install in my 1998 Lexus ES300. I can still return this thing if it doesn’t work out how I like it. I was hoping that you guys could help me!
First off here are some specs
General features:
•     DVD/CD receiver with internal amp (14 watts RMS CEA-2006/50 peak x 4 channels)
•     7" touchscreen with multi-angle adjustments
•     fits double-sized dash openings
audio/video features:
•     high- and low-pass filters
•     8-band graphic equalizer with 7 preset EQ curves
•     bass boost
•     built-in audio iPod control — Pioneer's optional adaptor required for viewing video content
•     compatible with Pioneer Bluetooth adapter, satellite radio, and HD Radio tuner
•     inputs: rear A/V and USB inputs, SD card slot, rear-view camera input
•     outputs: video output, 6-channel preamp outputs (front, rear, subwoofer)
Second…my questions:
First off about the car itself. I know that it has 4 speakers and the front two have tweeters and that there is one sub in the back. Also, this model has the 6 disc cd changer in the dash.
Question 1: Can I utilize the stock amplifier when I replace the head unit?
Question 2: Really just an extension of question 1…will I be able to control the stock sub through this setup?
Question 3: Is it possible to somehow wire in the 6-disc cd changer? If not I’ll just go without it…but it just seems like a huge waste. I don’t mind doing electrical wiring etc. just need to be pointed in the right direction…
Question 4: What are the impedances of the speakers? RMS values?
Now I did try some research first… It looks like I CAN use the factory amp. So I would assume the amp is separate from the head unit. It also appears that I can purchase a simple adaptor to accomplish this from Metra.
Metra part number 70.8112 – Toyota amp integration 15 pin
Is it as simple as that for the Sub / speaker control? (Will the Sub work?)
I have read on some posts here that people who tried to use the stock amplifier had background noise…is this something that has been solved? I have heard of ground loop isolators...what does this do? How do I incorporate it...
What other connectors will I need to purchase so I don’t have to cut any wires? Do I need a male or female connector to solder onto my radio leads?
Any help is appreciated!
