Ls400 audio setup thread (The Mother thread)
Rear: 4 ohms
Sub woofer: 2 ohms
You can confirm those accessing each pages of here. Things are all written in Japanese but simply click photos and see rear side of speakers. You will find figures 2 or 4 on those.
Most of after market amplifiers are designed to drive 4 ohms or higher. To drive 2 ohms would stress the driving transistors at the final stage.

Sounds this will be perfect for my needs.
i got a 1990 LS400
was wondering for whoever fit 6.5's was it a difficult fit?
or if anyone fit 6 3/4th's was it a difficult fit?
or shud i go w/ like a 5 inch and watever speakers?
My question is, has anyone figured out the maximum speaker mounting depth the door panel of the 2.5LS, or at least the 2LS (assuming things carry over), will accommodate? The CTX65CS component set consists of a 6.5" woofer with a mounting depth of 2.75" and a 1" silk dome tweeter.
I've read through this thread and I haven't seen any real figures as far as mounting depth on the speaker goes (for the 2.5LS anyways), though from looking at other generations, one could assume it's between 3" and 4", but clarification is always nice. As for mounting the tweeters, I will be using the factory positions while the rear may be coaxially (on the speaker) mounted or in a similar fashion as Lexkost has done (the point where the C Pillar meets the rest of the door).

The woofer in the CTX65CS component set is 6.5" with a mounting depth of 2.75". The ID CSX64 v.2 on the other hand, uses a 6.5" woofer with a mounting depth of 3".

This time I decided to give up on the Nak. I spent about $100 in 2012 to have an rear mounted aux-in and a front mounted on/off switch for it added (worked great) to the Nak but I'm though with groveling to get someone to even take a look to see if it can be repaired.
So, here is my $498 solution - not including taxes. $350 for the Kenwood at Best Buy, $14 for the Scosche dash kit from Amazon, $14 for a USB extension cable (I forgot to order a $5 one from Amazon) from MicroCenter and $120 for a Best Buy "Geek Squad" installation. I'm not counting the cheap 6 foot 3.5mm audio cable of which I have many.
I never in my wildest dreams thought I would let a Best Buy installer touch one of my cars ... until I met installer and LS430 owner "Brad M." at the Best Buy store in Overland Park, Kansas - the one at 9301 Quivira Rd. He told me that he had installed a number of head units in Lexus cars but had never replaced a Nakamichi. I could tell that he wanted to see if he could do it.
So ... Brad connected the Kenwood's harness into the OEM harness leading to the Nakamichi amp under the passenger seat. All speakers including the subwoofer work. No wires were cut. The new setup does not have quite the "warmth" and seat vibrating bass the Nakamichi head unit provided but it is still sounds much better than the standard system in my first (1990) LS400, better than the optional JVC system we have in our 2012 Prius wagon and better than the audio system of any other car I've owned. I'll be playing with the Kenwood's equalizer to see if I can tune it more to my liking.
I could have likely done it for less than $300 by buying the Kenwood online and installing it myself. But in this case I am very happy with the bang for the buck.
The reason I bought the DDX470 is that it is the least expensive double-din Kenwood with Bluetooth audio streaming. I did not want a double-din with navigation for several reasons: * Mounting location would be too low in the dash for a nav unit. * I can easily update my Garmin four times per year for free. * I can use my Garmin in rental cars. * My Android phone sends address information to the Garmin wireless (Bluetooth) though the Garmin Smartphone Link app.
My Samsung phone links to both the Garmin (phone profile) and the Kenwood (mobile audio profile) at the same time. One nice aspect of using Pandora through the Kenwood instead of directly from my phone is that - so far - I'm not getting any video or audio advertisements from Pandora - just like it works in the Prius system.
I ran the USB and 3.5mm aux-in cables through the console to the upper console tray. The Kenwood's microphone is routed up the driver side A-piller and attached to the center light cluster. I doubt if I ever use the Kenwood's phone hands-free feature. I like the way the Garmin's hands-free feature works better since, unlike the Kenwood, it is not necessary to touch the Garmin to use voice activation.
I was surprised that my phone automatically displays "Pandora - Kenwood" when streaming is controlled from the Kenwood. There is no sign that Pandora is streaming from my phone when I control it from the Prius head unit.
This "should" be the last modification I do or have done to this car although maybe this will make me want to keep it a little longer than next year's planned replacement. Oh, wait! I could add a backup camera to the Kenwood for $20 or $30 and maybe an hour of my time. Maybe just one more project on this car.

took me id say probably 2-3 hours maybe 4 total.
car is a 1990 LS400
my setup:
pioneer aftermarket indash
alpine amp
precision power sub w/ custom box (neighbor gave it to me, a heavy *** box probably 30-50LB including sub's weight)
next to do:
car speakers aftermarket ofc
alpine 4 channel amp
Difficult thing was putting back bottom cushion seats (had to get the hook in)
AND buying new RCA cables because the rca cables wouldnt fit in the holes provided behind the back seats, so i had to wire them to the sides next to the top seatbelt mount
if anyone ever have any questions regarding 1990 - 94 ls400 installation on subs or a headunit LMK!
