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.

Thanks and let me know if you need more help.

You could hook up speaker wires from radio directly as it has a converter built in. If you are using an aftermarket radio it has RCA jacks. So not needed.

Were do i plug in the RCA cables from the amp to a factory radio? do i need any sort of adapters if my stereo dose not have inn or outputs? and where do i hook up the remote from the amp?


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!

My alpine v12 turns on but no sound


no you don't have to hook up both of the power terminals. but should have it hooked up so you get the proper power to the amp. use a disubution block with two 8 gauge wires.

do you know if the radio's rca jack's are good? have you ever had another amp in the car? if it worked before try new rca's from the radio to amp. recheck all connections from amp to speakers and make sure no wires fell off.

Hooking up amplifier to stock radio in Lexus ls400 1991


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.

Amp


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.

Wireing


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.
