How to connect an amplifier to a radio without an amplifier output

How to connect an amplifier to the radio without an amplifier output on the radio ????

You can buy such an adapter from high to low, i.e. you connect this device to the speakers and on the other hand you have an RCA output for an amplifier. Generally, it is an ordinary resistor divider with a filter.

Hello. Connecting to the output of the power amplifier on the radio will introduce a lot of interference and distortion to the amplifier at higher power. The best solution would be to interfere with the interior of the radio. Find the signal before the power amplifier and from there, through the resistor divider, let out the RCA cable at the end.

Generally, it is better to stick to the second option proposed by davidos_77.

With adapters, you lose a lot of quality and the sound is empty in general.

It's not better to sell this radio and buy some JVC KENWOOD with at least one pair of RCAs.

A sure and reliable solution.

davidos_77 is right you can do it and it will be for sure better. You can also insert 100nF or 1uF capacitors (electrolyte) and it will play too. I am at home on Kenwood and it's ok.

that is, put these capacitors on the output wires of the radio ???

Not. dial the radio, see what the end of the power is there, find it on the net and see on the diagram which pins are written in1 in2 and in3 in4 because this is the most common. Then, at the end, find these pins in1 and in2 and solder the 1uF contacts to them with a plus to the tip and with a minus further along the cables to the boost and it must work.
If you are not sure if these pins will just match FP and FL or RP RL, find the sound processor on the board. Also find its diagram and from which the nodes the signals come out and where they are led to the tip. On the way between the Prock and the tip, you will also have threaded terminals or SMD 100nF.

HEHE I understand everything xD I think it will change the radio

Well, I can see that my colleague, after reading what my colleagues advise, came to the right conclusion.

Always a radio with RCA output will have better quality than artificial attenuation and cutting what the amplifier boosted.

RCA is led between the radio processor and the power amplifier, which means it has the cleanest signal.

For me, such a combination does not make sense at all. With this adapter you do not lose so much of the sound quality in order to play in the middle of the radio. Today I heard it with my own ears The only thing I didn't like is that the radio "sees" the sub as rear speakers and there are no settings on the radio to give you more control over the subwoofer. It seems to me that it is better to change the radio to one that will be adapted to connecting the amp and sub in terms of appropriate outputs and sound settings.

Loses because you raise the power amplifier on the radio first, then shut it down.

So only soldering to the input to the power amplifier.

But I still insist on radio from RCA.

Maybe you are right because what you write makes sense, but I did not hear the dirt on this adapter too much. And as for the radio, I will go to the ca store myself in my free time and see what is the difference between this adapter and the RCA radio. For now, I insist that the problem is in the appropriate settings, which the radio without RCA lacks .. But this is such a guess - I can be wrong.

Don't be offended but judging by your posts you are not very strong in CA.

The case looks more or less similar to the fact that you buy a CA for the car for e.g. PLN 5000, everything is beautiful and nice, decent bass and a nice front, but what if you listen to mp3 on the quality of the music from the ORGINAL CD is like from Warsaw to Paris.


Buy yourself one of the other ordinary Sony speakers in the front Jensen for this DEBILE tube from the countryside, first 1888W, and boast to everyone that you have a DECENT CA with a power of almost 2kW. :D

After that, the RCA output is the purest form of the signal delivered to the amp. besides, it has almost constant voltage and the level which is controlled by the radio module.

You're right strong in the ca I'm not. Although I am not an audiophile, I have hearing and I did not complain about the purity of the sound. However, I am not demanding. I doubt whether such a combination and "digging" the RCA from the inside of the radio will do the trick here .. I would probably not fumble anything there, pushed the radio and bought a new one with the RCA and better sound setting options. Because this is how art will be for art. And such advice with the DEBILE tube is probably only D ... they write. I know without offense that you wrote it in jokes - me too

Maybe I will violate the regulations a bit by writing a post under the post, but today I found out that this adapter is not so g .. like what some say .. I have a kenwood 3037A radio without RCA, I connected the amp through the adapter and I will tell you that there is no question of empty sound or poor quality. The subwoofer is a PB S-12 closed box, amp CP 1502. For me it sounds very good, strong and clean. So I have what I mean for a relatively small amount of money. And such advice as:
- change the radio for the better,
- carpower is a budget,
- better collect money and invest in a better sub
- housing BR
in my opinion in d .. you have to have and see for yourself what it is like to play in your own cart and not listen to such "smarts" and add cash, it is not known why I fit within the assumed budget and I am very happy with the purchase, and if I listened to some of them, I would just throw away 2 x more money to be also satisfied:] Regards

If you do not want to change the factory radio, it will do Especially if the signal is to be for a subwoofer.

that's the point, you just write change the radio, change the radio, change the radio, none of you came up with that someone might not want to change and spoil the aesthetics of the dashboard and leave the original. I think that drawing the signal after the preamplifier and before the amplifier (power amplifier) gives the same effect as the factory RCA, unless it is a typical sub output, we do not have any special control over the signal on the RCA radio. We have the same "volume bass treble" as the one that oozes from the speakers.
