I want to replace my car cd player with mobile phone.
I dont have enough space for both so i want to connect mobile phone directly to speakers via custom amplifier and use phone navigation and phone mp3 player.
I have four speaker connections on car audio connector. front (left,right) and rear (left,right). i think that car audio system have embedded filters for
bass and tweeters after cd player connection.
I could make custom amplifier with two IC TDA1553q but i need to split headphone output signal from two to four channels.
Should i connect directly splited signal to tda1553 input or i need to amplify little that signal? How to avoid distortion?
Do you have some suggestions how to make this possible?
Thanks very much!
