Re: trying to hook up amplifier to after market 6by 9...
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.

They make a type of Amplifier that uses high level input from the speaker outputs. Contact a company called Crutchfield.com for details and prices. You ca also have a radio shop install preamp output RCA jacks to the factory radio, do an Internet search for shops that do this type of retrofitting.
Hi Lo Adapters Hi/Low adapters are devices that installers use to convert a speaker level stereo to RCA levels so it can be hooked to an external car stereo amplifier. You can cut the speaker wires and hook the hi/lo adapter right up or you can tap onto existing speaker wires without cutting them so the speakers still play while the tap gives you a connection to the hi/lo device for adding something like a subwoofer amp to the existing speakers.... We have hi lo converters in TWO CHANNEL and FOUR CHANNEL configurations and we have them WITH and WITHOUT adjustments.. The adjustable hi/lo converters allow you to fine tune the hi/lo device to match other levels in the car or to make sure the match between your stereo and amplifier is a good match.. The adjustable line converters are the most popular.. We also have some specialty hi lo converters that have special radio plugs on them that may plug right into your factory stereo. Now you can install an amplifier with your factory radio or install a new radio with your factory amplifier!
Most factory radios do not have RCA outs, but most will have a remote wire. Usually used for a power antenna option. Your remote wire from the amp could be hooked to the power antenna wire on the factory radio and it would work great for turning on the amp. As for the RCA inputs on your amp, you will not be able to use them without RCA outs on your factory deck. Although most amps offer a high level input alternative and will use the standard speaker level out on your factory deck. This means the rear channel speaker wires from your factory deck will be used to feed the signal to the amp. You will have to check the instructions and manufactorer recomendations for the amp you are trying to hook up. Have fun and good luck!
i just sent you the manual for your am everything you need to know is in there. i also have tht plug if you need it. but will only be used for high level inputs for factory radio's if you have a after market radio use your rca jacks. or if you want you could use a converter if you have a factory radio that makes speakers outputs from the radiointo rca jack that will go into the amp. the rca'sare the best way it will sound much cleaner. good luck
Hi Robin, I think I may be able to help. The instructions are referring to an aftermarket stereo and not the factory one. Most aftermarket stereos have a blue wire that runs either the power antenna or an accessory that turns on with the radio(amp, eq, power crossover,ect.) As far as the RCA cables, once again, most aftermarket stereos have RCA outputs for an amplifier. Factory ones don't.You can go to Wal-Mart or ABC warehouse and buy a wire harness just for this particular application and then all you do is plug the harness into the factory harness, everything is all pre-wired so there is no guesswork involved and no mistakes.
if its the factory radio more likely it dont have RCAs ..You will need a 'speaker to line level adaptor" ..This has 3 or 4 wires at one end and RCAs at the other.simply connect a left and right set from behind radio or from rear speakers into left and right sets on adaptor ..then connect your RCA cables side to amplifier using RCA wires.
