The old pioneer car radios solved this problem by supplying the battery power to the radio from the amp. When the radio turned on, it began to draw more power from the amp supply lead and this would turn the amp on. It was a simple circuit in the amp that only used one or two transistors. You may need to build this circuit or find a manufacturer of a similiar circuit. In the short run, you can use a small toggle switch to supply the trigger voltage (+12 volts) to the trigger wire connection on the amp. Good luck.

Technics stereo


These units are known for having bad solder connections develop over time. Would have to check bottom of main board for bad connections especially around amp ic's and voltage regulators.

Sansui 221 stereo receiver comes on, but no sound. Yes the wires are plugged into the receiver. When first turned on sound came through the speakers, then I noticed that the lighted back drop started to...


Since this receiver is old-school stereo-only from the pre-subwoofer-era HOW are you driving the sub? Please refer to ITS manual and connect it properly. The speaker outputs for this box are for single speakers only.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Harman/kardon avr 110, cuts off 3secs after cut-on i hear click in back by the power source


if you have your speaker wires plugged in when you turn it on try unplugging them and turning it on to see if it turns off again. if it stays on after the speakers are connected you have a speaker wire shorting somewhere or a blown speaker and the amp is turning off into protection mode. if thats not the case check the fuses inside of the amp and make sure they are ok. and while its apart use a can of air to clean off the circuit board to make sure there isnt ne dust causing a short on there also.

My stereo is connected to the computer..and for some reason it isnt playing and music or sound in general....it says the the phones are engaged...but there are no headphones in the stereo..what do i do?


ensure the cord is fully inserted.

There may be a problem with the wire.

get a new higher quality wire is all i can sugest.

like instead of going dollar store. go somewhere else like radio shack a get them for $10 and they allmost never break down.

Someties the wire need to be lightly pushed up or down or side to side. To ensure the connection. But if you haft to do that. Just get a new wire.

I turn on my stereo and the receiver says protect why


your speaker wires are touching if the plus or minus or (red and black wires) are touching it can blow the amp this is a protection. Check all the speaker wires on the back and makes sure they are not touching.

Need wiring diagram for jensen ka 4040hlx 500 watt amplafier


Hi Rordawg01

Pretty straight foward. You need to connect power via a heavey duty cable direct from the battery to 12v terminal. Fit a fuse in line at the battery the same value as that on the amp(30a is good). Ground(chassis of the vehicle to the earth/ground connection. The remote terminal on the amp connects to your head unit to turn the amp on and off when you turn the stereo on and off. . You will need to supply signal via rca sockets to the amp also, these then connect to rca connectors that can be found at the back of your head unit.

Dont forget to disconnect the battery when doing 12 volt wiring on your car. If you wanted to get up to speed with installing car electronics, check out this site. It may help you get up to speed.

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.
