When I turn on my car stereo,I don't have volume unless I unplug the RCA jacks from the amp.After I unplug them, I can plug them back in, and the sound continues.Should I be connecting the stereo to the amp using the RCA jack inputs, or the high level inputs? What are the PINs for the high level input? I didn;t get the plug when I got the amp. thx.

You did not specify exactly which Jensen amp you have. None of the Jensen PowerPlus series I found had high-level inputs. You can go here and select your amp to download the manual. They should also have the connector for speaker inputs.
Most amps that have both high-level and RCA inputs allow you to use one or the other, but not both at the same time. If your head unit has RCA ourputs, those would be the ones to use, because they generally provide a cleaner signal to the amp with less noise.
I have an amp that has both high level inputs on RCA inputs but when i plug in the RCA in puts it doesnt work and i cant find out what i plug into the high level input. so what do i plug into the high level input?

You didn't include make and model TV; so only generalized answers are possible.
Typical RCA phono jacks like those shown in the blue box of the stereo amplifier below:
will accept cables to connect to other audio devices. The audio RCA jacks are color coded RED (right) and WHITE (left) for low level stereo signals. Some have YELLOW jacks for Standard Definition video, ORANGE jacks for AC3 Digital audio and newer amps have HDMI jacks.
Connect the TV's audio OUTPUT jacks and a stereo pair of unused audio INPUT jacks on the amplifier with cables that have ends that match each. Turn on the stereo & TV and select the input on the amplifier that matches the stereo pair of inputs you used to connect to the TV. Adjust the volume to hear the audio over your stereo system's speakers.
Use the HDMI or AC3 sources for superior audio - including 5.1 (or better) Dobly Digital when possible. Otherwise, a standard 2 channel stereo program will be heard.
You would need a mini jack to stereo rca wire. Insert the mini jack to your Ipod's headphones, then plug the stereo rca to your amp inputs. If it's a receiver, plug into any of the inputs (aux, tape etc) except "phono or turntable", then switch to respected input on the receiver. Be sure all volumes on both units are down during this process, then gradually turn up both volume to normal level.
First, know that you need either high level input or low level input, but not both. Low level input is preferred (RCA cables). If you must use high level input because your head unit doesn't have RCA jacks, you connect the speaker outputs from the head unit to the high level input of your amp. The high level input plug probably has a black wire, this is "signal reference ground". A pair of grey wires which are right positive (grey) and right negative (grey with black stripe). And a pair of white wires, left positive (white) and left negative (white with black stripe).
The amps are located inside the radio. Most in-dash receivers that provide for "pre-amp outputs" also called "low level outputs" do so by providing female RCA type jacks. These are often found at the end of a short (4 - 6 inch) cable and are usually color coded red & white or red & black (some receivers provide a yellow RCA jack for video in / out, too). To use these RCA audio jacks, you need to realize that one jack is for the left channel source and the other is for the right channel source for a stereo signal. You will have to connect a compatible plug and cable of enough length to extend to a remote amplifier's RCA input jacks. The vehicle's speakers would also need to be connected directly to the same amplifier's output terminals. Using the two audio (left and right) RCA jacks will only allow the radio to control balance of the left and right audio, no fader (front and rear) control is possible. To get fader control, you'd have to either have a radio with four RCA low level output jacks (front L & R *and* rear L & R), or use the radio's speaker (or high level output) wires and connect them to the amplifier's speaker (or high level) input terminals.
All unused receiver wires should be terminated in a wirenut or securely wrapped in electrical tape to prevent accidental contact with grounded metal or other wires behind the dash.
If your receiver has a dedicated subwoofer line level output, we recommend connecting your subwoofer to this jack. Most receivers will have just one (mono) subwoofer output, while quite a few subs require two inputs. You can use an RCA "Y" adapter cord , which is a cable with one female RCA jack at one end, and two male RCA plugs at the other. Some receivers require menu settings (such as "sub-on" or "front speakers-small") that must be made before the sub output will be active.
You can not connect the speaker lines directly to the RCA inputs of your amplifier. But you can connect them to your amplifier if your amp has a high level input. Most of the time it looks just like the speaker jacks of the amp, but smaller. It will be labeled high level input or speaker input. Sometimes an amplifier will have a jack for a wiring harness just for this purpose. Some amplifiers have them and some don't.
If your amplifier does not have them, you can purchase a line level adapter at most anyplace that installs car stereos. it converts the speaker level to the proper level of the RCA input. Just follow the instructions on how to connect it.
If you try to connect the speaker outputs directly to the RCA input of the amplifier you will blow up the pre-amp in your amplifier.
I hope this was helpful to you, if so a good rating is always appreciated.
If your amplifier has what they call High level inputs (basically inputs on the amp that you run the speaker wires from your radio into), you can splice wires from where the connectors are on your rear speaker(s), still leaving the speaker hooked up, and use those as an input into the amp. If your amplifier does not have high level inputs, a convertor is available to turn an audio signal from your radio output speaker wires ( spliced in just as above, leaving the speaker hooked up), into an rca output jack. Or the best thing to do would be to buy another say 2-4 channel amp w/high level inputs and rca inputs and outputs, and run your rear speaker wires into the amp. Then you'll be able to run the rca cables out of that amp and into the sub amp, and you'll have the new amp to power your rear speakers or rears and fronts. That would be ideal. But, A convertor is your best bet. Got em at best buy, circuit city, etc. Hope this was helpful.
I believe that this model Sony amp includes High Level inputs. Those allow you to connect the normal speaker wires coming out of the factory stereo to the amp. If for some reason it doesn't include the inputs you can buy a high level to low lever converter that will give you rca from the factory unit.
Your problem stems from the fact that the CDA-7892 is not equipped with an RCA aux-input jack. If you're plugged into RCA connectors at the back of the head unit, they're outputs, not inputs. The sound you hear is just feeding back through the outputs and into the head unit's amplifier.
If you want to play your iPod through this head unit, you need to purchase either the auxiliary input adapter (KCA-121B) or iPod adapter (KCA-420i).
The amp is a jensen triple play 1,2,3,. That's what it say' on the amp. It is an older model. I got it from a friend.
I still need the PINs. I didn't get the plug.. THX.
The RCA input says low level input. Should I be using the high level input, since the volume is powered, coming out of my stereo?
