Alrite here's my problem i have a 93 Lexus es300 and i installed a new a deck in my car along with a sub and amp. will after the installed i been having problem with the deck staying on. if i play my cd's i am only able to turn the volume up to 19-22. if i go passed that then the deck cuts outs. i tried changing the deck on but it still does the same thing. any imput would help me out a lot thanks.
Is Lexus a Toyota with a little more leather? If so I have a few questions. Where did you get power from? How did you deal with the factory amp, also where is the factory amp? (this is important) Is it behind the radio or is it behind the glove box above the kick panel. I need to know. You have a power problem but we need to figure out why.
yes lexus is toyota with a little more leather. i bypass the factory amp because when i bought the car the harness was chopped up. when i got the car the amp was mounted underneth the pass. seat.
I am not familiar with that set up. With the Avalon, the radio gets its main power from the amp. Power sources behind the radio are unreliable. I am going to assume that your car is the same way. I hate working on a problem without diagnosing it properly. If you have a DVM or VOM check the constant power at the radio, as you turn it up does the voltage drop to less than 11-volts? If you do not have access to a meter, then run a wire (temporary) to the batt positive and hook it to the radio. Is the problem still there. Most Toyotas do not have a ground wire in the harness. Make sure that your radio is grounded by attaching a wire from the radio chassis to something metal under the dash. Let us know whats going on
