I am trying to use my old car stereo with amps for indoor use. The kit includes

Headunit - Pioneer DEH X4690BT

Amplifier - Hertz EP2 2 channel amp

Components - Rainbow Experince Line 2 way components mounted in individual boxes

Situation

When i run everything from 12v 7 ah battery things work like a charm provided i take amplifier remote current from battery

By connecting headunit to battery i checked amplifier remote output in wiring harness ( blue cable with white line) and got around 11.99 v

Problem

I am trying to use a 12v 10ampere transformer to to run the system. Connecting the amplifier remote cable to headunit amplifier remote cable does nothing.

Connecting the amplifier remote cable to its positive power input or to transformer directly results in amplifier going in safe mode.

Need guidance.

Your car audio amplifier expects 12V DC power. Your battery provides DC power, hence it works.

Your Transfomer converts AC to AC. You would need to add a rectifier and filter capacitors (rectifiers convert AC to DC but also create some noise that needs to be filtered) to the secondary of the transformer to have a clean DC power supply.



Lastly, I request you to post using correct grammar and spelling. I had to correct 19 typos in the short message above. Most were as silly as skipping articles like "the", using a lower case "i" instead of an upper case "I" and compressing two words into one word.

I understand some of you young folk like to use mobile devices and do not like to concern yourselves with grammar and spelling on your Whatsapp messages but here are Team-BHP we work towards a more precise form of communication. I do not wish to come across as some senile old fastidious geriatric but well-constructed sentences benefit everyone.

Thank you.

I addition to what @navin has pointed out regarding AC/DC current, a simple circuit diagram would make things clear for us. Even a hand sketch would suffice.
