Is it possible to install a car stereo without disconnecting the battery cable? I have heard someone mention a harness system where the battery does not have to be disabled for installation. Is this possible?

Yes, it is possible. There is no "special harness" that allow this to be done any easier or safer. If you have a proper wiring harness for the radio that doesn't expose any bare wires or involve cutting up your car's original wires, it's pretty safe to do. You just unplug the old radio and plug the new one in place. But no matter what kind of wiring harness you have, it's always better and safer to disconnect your battery to keep anything from shorting out.

When the vehicle is off and stereo is off the speakers are making loud popping and banging noises all the time over the last week? when the vehicle is running and stereo on no popping noises


This can be tricky; there are several things that might cause this 'phantom' problem. You did not state if you have an alarm system. The alarm may be tied into your speakers and/or linked to the stereo itself. I would not initially suspect a ground issue since the stereo works well while powered. I would suspect a power feed issue. This can be tested by removing the fuse for the stereo and seeing if the issue continues.If the problem stops, the source may be internal to the stereo and you may need to get an aftermarket stereo - or pull the fuse every time you stop ( sucky solution, I know!) . I think this may be an issue resolved by a reputable stereo shop. Possibly a strategically placed Diode may solve the problem - a hands on diagnostic is certainly called for. You did not mention if the problem decreases or stops overnight. I would think this can cause your battery to drain over an extended period of time - and ruin the speakers too, if they're not affected already. I would try contacting the Dealer first and, as this problem has gone unresolved for so long, see if you can get them to replace the stereo or at the least pay the stereo shop to fix it.
best of luck and thanks for using Fixya!!

How to install a Kenwood kdc 138 in a 1992 Ford Escort LX?


if its anything like my 92 ranger you take the dash apart around the radio and the stereo should unscrew, in my ranger the new cd player went in without any extra harness as it was the same size as the stock, if not you can but harnesses to go where your old stereo did, to connect the speakers you can buy a ford wiring harness from walmart or any store with an audio department. these plug in to your vehicles wiring harness so you don't have to cut it out, after that you simply match colours from the wires of the new cd player to the wiring harness

My stereo sysytem is a mini stereo: serial number 10200055. It currently says "protect", what is this and how do we return our system to normal operations?


Hi there,

When the word PROTECT appears on this display, this means the unit has detected a critical fault which could potentially cause harm to your stereo system.

The most common cause is a short circuit somewhere - something even as simple as loose speaker wiring could cause a short, triggering the Protect message.

You will need to determine if there is a possible short somewhere, so I recommend you start by firstly turning power OFF, disconnecting all speaker wires, then turn unit back ON.

Operate the stereo (without speakers) and turn volume up:
  • If Protect message appears when turning volume up, then stereo unit itself has an internal fault
  • If no Protect message appears, then suspect the speakers may be causing the issue.
  • Reduce volume and turn unit OFF
Re-connect speakers (ensure the connections are secure), turn unit ON:
  • If turning volume up triggers the Protect message again, there is an issue with the speakers or connections

Hope this helps.....

I have an Onkyo TX-8522 stereo system. I am trying to connect my iphone to it so that i can play music there (both from Pandora and from my own music from itunes). I was wondering if this was actually...


Yes it is possible. Any audio device with an earphone out jack can be connected to a receiver by using the CD input or the AUX input jacks (white and red) on the receiver. All you need is an adapter cable with the stereo 3.5mm plug on the iPhone side and the 2 RCA connectors on the receiver side. You can get these for $2 or so at Amazon.com or at Radio Shack. Adjust the volume and select on the receiver, the input you used to connect and enjoy.

See above link for one example of the cable.

1998 beetle installing new radio but yellow and red wires always hot even with ignition off


i believe you are supposed to disconnect the negative on your battery, but only if you have a memory saver plugged into your cigarette lighter as to not lose any vital computer settings. then replace your stereo and plug the negative back on to your battery and remove the memory saver.
I've been researching about replacing the stereo because mine has fallen apart and i've just ordered a new one plus the ipod connecting kit.

Harman Kardon AVR 245 Receiver PROTECT Error Message/Shutting Down All Equipment


could be your receiver only, it has tripped due to discrepancy on the output stage of your amp. that cracking sound in one of your speakers could have caused the trouble. it is possibly shorted. but in your case it could have damaged already the amp that;s why it would not turn on. normally it will first trip, turn on then turns off. but to stay off and not to turn on again is major problem of the amp. or maybe it emanated from miscabling, probably the ceiling speakers got connected to a high output or main amp. but try removing all speakers first then turn the unit on. see if it does power up.

How do i install a subwoofer and amplifier to an exhisting car audio system


Hi,

The basic would be to wire the sub amp to your batteries with the trigger/remote wire powered by your car stereo/head unit. When your head unit is turned on it will in turn power up the sub amp. Of course the sub woofer need to be wired to the amp. For the signal/audio wiring, normally, the head unit has a stereo RCA female connectors at the rear intended to be connected to external amps through a pair of shielded/audio cable terminated both ends with RCA males. Some units have a special RCA specifically for subs. Most eternal amps also uses RCA for their inputs.

If the existing car audio system has already an external amp and your plan is to add on to this, the audio/signal from the head unit could be split to provide both for the existing and the new sub amp.

If the existing car audio does not have an external amp and their are no RCA connectors at the rear of the head unit, it is still possible to connect an external/add on amp by using an adapter that connects to the speaker wires of the head unit and converting it out to line level (through RCAs) appropriate for the input of the amp.

Hope this be of help/idea. Pls post back how things turned up or should you need additional information. it would also be nice if you can post brand/model of your head unit and intended sub amp.

Good luck and kind regards.
