Right page with connectors is how it was. I did have to use a cheap ground loop isolator to suppress engine whine if I remember correctly but it didn't effect sound quality. That would be your best bet. As mentioned in a later post in that thread, adding resistors probably isn't the way to go there. They count on this ground feed to be chassis ground and they count on it being the only ground in the equation. It just tells how impossible it is to do so.
Bluetooth compatibility: all Bluetooth capable smartphones, including latest Galaxy S series and iPhone. What it does is tap into one of your door speakers positive and negative output cables. The gain control on the amp counter-reacts to the voltage from the head unit, therefore, the hiss will get louder as you turn the volume down and quieter as you turn it up. The shop is Custom car Alarm in Pleasant Hill, Ca. Posted on Aug 19, 2011 If you've purchased a new navigation disc and it won't read it, you will probably need to get a firmware update for your navigation unit.
Wired through the door wiring using a coat hanger, and under the carpet to the amp. Move seat all the way up, remove plastic covers at base of seat. Either a custom system or a boxed solution but the factory enclosure is garbage and changing the drivers in there wont net any appreciable benefits. All parts are backed by the manufacturer's warranty and shipped directly from Lexus dealers. However, when I got the part right, the new disc worked like a charm. Normal speakers are 4 or 8 typicaly.
How much of a problem this will be depends on the quality of the stock amplifier. I believe you'll be good after the procedure. Theres nothing available in the right ohms. There are a few write ups on swapping speakers out. Anytime you're diving into a 100 Series stereo replacement I'd just count on bypassing. I'm wondering if anyone has swapped theirs out and what they used. Normal speakers are 4 or 8 typicaly.
Fortunately there are some good solutions to improve things. Takes 15 minutes total start to finish. I ordered a disc online, thinking I had the right one. Conclusion By now, you are probably wondering if you can do all this yourself. Long story short dont bother with aftermarket.
I just reused the factory spacer and screws. However, introducing extra items into the signal path isn't good, and they tend to be pretty inexpensively made, so it would be better to just go straight to high level inputs on the amp. Place brackets in same position on replacement amp. You would need to run one knob for master volume and individual knobs for each channel. The 98-99 Land cruiser has isolated grounds in the head unit and amp and that makes it completely incompatible with aftermarket head units where they always use the hu chassis as a part of the ground circuit. Second, suspension and braking failures.
This way, there is less space to fill between the unit and the center console. All of them will require some poking around behind panels and some wiring. After some research on this club and taking to stereo pros, I decided to change both head unit and speakers. When you mix the two you will now hear any variance in the two grounds through the speakers as a hiss and whine. It fit with virtually no modifications.
As far as the brackets, I went with the Beatsonic kit at the time, but that one on eBay looks pretty identical. It is major surgery, as you would have to take apart the door panels, side runners, glove box, and may be even the firewall between the dash and the engine. It fits nicely under the passenger seat. It shared with Land Cruise in floor plan and most body panels featuring in body-on-frame configuration. Do not try to remove with a phillips head screw driver. Hope this helps a little with options. Left page was what I used.
