For the trim, what I used to do in the ghetto days was to take the styrofoam trays from the meat at the supermarket, wash it, and cut it to size. The "premium" meats came on black trays, so that way I didn't need to paint it.

Now-a-days, I take a heat gun (jumbo hair dryer) to a plastic sheet from the hobby store. If you still have the factory stereo, you can use it as a template. You just have to take it slow so that it doesn't melt too fast.

Aftermarket head units may need to be pushed out about 5 mm to match up with the front of the dash. You'll need to find longer screws and a few washers to bush out the unit. Each unit is different, so measure after installing, then go find the parts.

 

I have just purchased a Kenwood KNX7100 GPS/Head Unit and am just preparing to install it into my 2000 LX470 w/Nakamichi. I have the wiring diagram and it looks like a fairly straight forward install. I plan to use the Nakamichi power amp and the current question is: should I use the preout audio (RCA plugs) or the output from the power amp into the factory wiring loom? Thanks in advance for your response.

 

I'm installing a Kenwood DNX5120 in a 2000 LX470. Did you complete your install and if so, what outputs did you run to the amp? The pre outs or the amplified outputs? Thanks

 

I ended up taking out the factory amp and running the amplified outputs from the Kenwood directly to the speakers. I put in an amplified sub and use the sup pre-out.
I removed the factory amp and re-wired the harness to pass the pre outs directly to the speakers.
The install took more time than I expected but was well worth it...

 

Thank you for your help. I finally got my head unit in yesterday. I ended up using the existing amp. I ran the regular speaker outs to the amp and it works fine. I did have to jumper the ACC to the amp remote on to get the amp to turn on with the radio. After doing this, I think I could have used the Power Control Wire to the amp and accomplished the same thing???

I'm just waiting on my XM unit(still on order), so I can finish all the wiring and then start on the console adapter to make it look good.

 

Glad you got it working. The reason I chose to remove the amp is that I couldn't hear a noticeable difference in the sound with the factory amp in the circuit. This is one of those projects that was really worth the effort. The black plastic trim which covers the space around the radio looks great but you need to spend a little extra effort when you cut it to make it fit just right. Let me know how it comes out.

 

I'm contemplating doing a Kenwood DNX install on my '00 LX470 as well. Any pictures and/or detailed descriptions you all could provide will be very appreciated.

 

Unfortunately I didn't take any pictures of the install, but I would be happy to answer any questions you may have.

 

i'm doing a dnx5120 install as well and all the shops tell me i have to bypass the amp. i said nope. thanks to you guys i see its possible to keep the amp. i've got all my speakers connected and the powered, i can even hear music, its just really quiet. this has led me to believe the factory amp is not powering on. i see i am supposed to 'jumper' the acc wire or something like that but i am confused as to what that means. any advice would be greatly appreciated!

Hey, I know this thread is old but I was wondering if you guys could help me install Clarion NX409 into my Dad's 1999 Lexus LX470.

I followed the wiring diagram but I'm unsure where the White +B wire is suppose to be connected too. Does it connect to the +12V main power on the Clarion unit?

Here are pic of the stock harness I cut:


Pic of how I connected the Clarion to stock wiring:


Thanks

 

My factory unit had a CD player AND a cassette player. That's two motors needing 12V each. So I suspect the two 12V B+ wires are there for setups where there are two devices to drive. When I installed a Sony CD only system, I just left one of the 12V B+ wires taped up.

 

Ah ok. One of the fuses blew out so we have to get that replaced first. So I guess I can leave the white wire 12V taped up. Did you also have to Jumper the ignition wire to the Amp wire (Black/Red) too? For that connection it would be wire connected between the Amp and the ACC right?

 

You guys know that a plug and play kit is available instead of splicing and cutting wires right?
