Post SC Pioneer Premium System

After days of searching and reading about conflicting information I finally got tired and decided to take a measure tape with me to measure the factory sub and to crawl into the trunk of my sc with a flash light to take a look at the stamped info.

So, the finaly result from the readings and my finding is

The Lexus Premium Sound System(with CD changer) on SC's :

The front and rear speakers are 4" and 4 Ohms (gotta luv the search)
The sub is 10" and 1 Ohm (this is where the searched info conflicts)

Now, does anyone know the factory power rating of the system going into each of the components? Thanks!

I thought the factory sub was 4 ohm impedience (sp?). It should say what it is on the back of the woofer basket. If I can find mine today, I will look. As far as power, I don't know. It may be stamped on speaker amp, which is located under the CD changer. Click here for a how-to on removing the CD changer. And click here for a how-to on removing the amp after the changer is out of the way.

I think u are talking about the Nak system

Yes, from all the stuff I've read the Nak system has the 10" sub with 4 ohms impedance.

I'm just talking about the pioneer premium sound here, not the Nak. All the info about the Nak is pretty consistant, but everything about the pioneer is simply cloudy. BTW, the pioneer system has a seperate amp beside the woofer, the setup is not the same as the Nak 5ch amp under the CD changer.

I'm talking about the Pioneer sys., too. I have the same amp setup and the sub says Pioneer on it. I'll look again...

Just to clear things up, the 10" sub in the Nak system is 5 ohms, not 4 ohms.
The 10" sub in the Premium system is 1 ohm.

The 10" sub in the Nak system is 5 ohms.

Note: I originally thought it was 1 ohm, because I had assumed that my car had the Nakamichi system due to the fact that it has the 12-disk changer. What I actually have is the "Premium" system, with the 1ohm 10" subwoofer. I hate mis-information on web boards, but I'm ashamed to say that I contributed to it, do to an assumption on my part. I'm sorry for any inconvenience this has caused.

The 10" sub in the Nak system is one (1) ohm.
Thanks for correcting!

Default Stock Speaker Size

Ok - After a very long and complicated process, I have finally put an aftermarket headunit, speakers and subs in my car here is the info:

1996 LS400

Stock speaker size Front 5.5" Can Fit 6.5"
Stock Speaker size Rear 5.5" Can fit 6.5"
subwoofer ???? Didn't look at it but I think they are 10"

I went from stocks in the front and added boston acoustic component 6.5". They can fit once you cut down the speaker panel a little. In the rear I added 6.5" MB QUartz. Only reason I even put 6.5" is because I bought the wrong sizes.

As far as headunit goes. I went from stock pioneer to an aftermarket Alpine. Much better sound. also added a 10" JL AUDio 10w6 v2, which now sits behind the driver seat. I couldn't put it in the trunk because my gas tank is righ tup against the rear seats, and there is a firewall around the trunk. Couldn't hear the sub well enough. All and all this job was a nightmare. and the whole car had to be rewired. But, I am happy now. Will post pics later.

I don't want it behind my seat either, but there is never anyone in my back seat anymore (the good old days), but I am thinking of seeing if I can actually take my 10w6 and mount it where the stock subwoofer is? Do you guys think that it can work???

Let's please reserve this thread for posting FAQs like speaker sizes in specific model years, etc

At some point sson I'll delete the extra Q&A from this thread.

Well, as Dave said, we need to keep this thread to FAQ and not actually asking questions, but...

Try contacting a member named Altran. I got one from a website (can't find the URL anymore) last spring and it was apparently made by him. Here is a pic:

Question

I just bought a 2000 ES300 Platinum series Friday and I need some help with replacing the head unit. I want to know where can I find a good kit for my aftermarket kit to fit in. I also would like any suggestions when it comes to hooking up an aftermarket amp. Thanks.
