  1. Okay, now I'm confused, too. I did a complete rework of our '95 ES300 stereo, and I've done several installs with Apline systems, and I'm not sure what you are referring to when you talk about the harnesses. There is a 'wiring harness' that comes with your new headunit, then there is/are the factory wiring harnesses, and then there is an interfacing adapter harness that I'm guessing is what you went out and bought so you can connect to the factory speakers/amp without having to cut wires, right?

    So, I'd need to know the Alpine model to get a better feel of just what inputs/outputs you have. If it's anything like this Alpine head unit, you've got RCA's for your line-level input and outputs... none of them should be the amplified speaker signal. I'm presuming since you are connecting to the RCA's that you are not using the Alpine head unit's internal amplifier and you are routing the head unit through the factory amp. If that is the case, then have you checked your ground? Is it clean? Often speaker noise is caused from picking a 'dirty' ground location. "Buzz" noise in the speakers could also be caused from from a dirty power source, but then there is usually an isolator on the positive lead of the headunit, but that only gets you so far in cleaning up a noisy line.

    It could also be an incompatiblity of the factory amp with the new head unit (impedence, circuitry, etc.) which is making the system succeptible to picking up noise from every other periphial electrical operation of the car.

    Does your Alpine head unit have a nice internal amp in it? My last Alpine had a whoping 45 watts per channel, so I ran all my speakers off the new head unit. I just bypassed the factory amp and ran straight to the speakers from the Alpine.

    I would also recommend running a low gauge wire directly from the battery (fused at the battery) through the firewall and to your headunit for main power. That will give you the cleanest power available.

    One last thing to note, on our '95 there is a hands-free option somewhere in the factory radio (or so I was told) that is wired through the power antenna. If I unplugged the power antenna, I would lose sound to the front speaker. Weird. Perhaps some of this cross wiring for other applications is causing interference in your system. It's hard to know for sure.

    I guess there are a few things to look into.

    i have an alpine cda-9884

    on the club lexus forum i posted on the guy said i should try by passing the factory amp and run the wires directly from the alpine headunit to the factory harness that comes from the car, i think that might be a real possible solution, i was also the car has a premium sound system, does that affect anything at all? i think im going to try to by pass the amp, i just kinda nervous about !Removed! things up with the factory harness cause if i do then im screwed

    he gave me a wiring guide, for the factory harness, check it out added it as an attachment

    and about what you first said yes.

    i have the harness that came with the alpine headunit. then the factory harness that connects the amp and the speakers. and then i went out and got another harness adapter like thing that has the 4 rca's coming out of it, so i would not have to cut any wires, its the rca's that are messing things up

  2. so i just recently got a 93 es300 first thing to do was install an aftermarket headunit, i got an alpine. so i went out and bought the proper harness and what not, everything works perfect BUT anytime the headunit is on the speakers make this sorta static'y sound and it comes from all the speakers and if the car is off and i turn on the headlights or even the parking lights its make a little loud static sound coming from the speakers, now for alpine headunits you have to buy this special harness that connects to harness in the car itself, and on that harness there are 4 rca's 2 red and 2 white that you have to plug into the back off the headunit in order for the speakers to work. and then you have a few other wires that you hook-up to the harness that your headunit comes with that goes into the back of the headunit such as, power, ground, amp power on. whenever i take out the rca's i the sound goes away, but the i have no sound, because the rca's are the only way i get sound because of the special harness, anyone experience any problems with aftermarket headunits like i am, please help!!!

    i was thinking, what if i was too cut off the top plug part of the rca's and just try to connect the wires directly with the un-used harness wires that are speaker wires coming from the (headunit) harness that i matched up the power, ground amp power on and a few others

    if i confused you please let me know and ill try to clear things up

  3. Hey everyone, I'm a new user to this forum. I'm also on clublexus. Anyways I have 2 Lexus vehicles. A 1992 SC 300 and a 1993 ES 300 Coach Edition.

    And the Stats:

    I'm the 3rd owner of both these cars. I bought the ES back in 2004, and the SC in 2005.

    The SC 300.

    I spent $6,000 buying the car.

    91 Octane gas used.

    Insurance (6 months) : $1,500 (Liability only)

    What I do with it? Take it to the max speed (about 152mph, then the rpm redlines like crazy) Drive it daily to school, work, show off to the integra-civic racers what a 2JZ is all about.

    The ES 300.

    It's a coach edition (rare for a 93+)

    Again I got it for $6000.

    It has 147K on the chasis. (I blew a head gasket)

    I just dropped in a 30-50K JDM motor.

    The motor (long block): $748

    Mods: Gold License frame - $50. K&N air filter replacement - $60. New projectors - $400. Silverstar bulbs - $40. Blue Fogs (Equivalent to HID lighting) $40. TSW EVO chrome rims: Priceless (it came with the car, but I sold them for $250, and got some OEM wheels, the tires for the TSW's were wearing out too fast, and the rims were scratched up already) And again, the Gold Emblems. NGK iridium spark plugs - $26

    Insurance (6 months): $820 (Liability only)

    What I do with it? Park it in the garage from haters. (I can't believe that people hate on my ES when I had the TSW EVO rims, dang it's only an ES.. with better looking wheels than now)Took it to the max speed to 135-138 once (Yes I am crazy) Drive it to school, work (switch off with the SC300 when I'm Low on gas) My dad uses the car sometimes for trips to L.A.

    Pictures: The ES picture is in poorer quality because it was taken with a philips key chain camera. The pictures were taken at different times.
