Is it a good solution for me to add a bluetooth to my car audio?

I have a old autoradio (cassette and not AUX input ) in my car. But i don't want change because it pretty. I just want to add bluetooth. I leave fm receiver side for the true audio / radio.

I want to know if i purchase both parts in Kynix:

  • TDA7388 four-channel 41W audio amplifier board
  • Bluetooth home-car receiver adaptor
I connect the audio amplifier with bluetooh receiver and power amplifier with speaker and i add a switch, to switch(speakers) between true audioradio/power amplifier.

I know i must add a power convert 12V->5V for the Bluetooth module.

I want to know if this is good "cheap" solution ?

I don't know about doing it that way.

But I just sent my STOCK radio out to have the right channel amp fixed, and while he had it open I asked him to add a 3.5mm jack. So for $20 he can add an 8 foot cable that comes out the back of the radio, or for $35 he adds the jack to the front of the radio.

I got this from amazon to serve as a bluetooth reciever. Bluetooth Receiver,

Tony can be reached at it might cost more if all your doing is adding the jack, but he already had mine open to repair the amp so that's what he added to the price for the jack.

You could add a bluetooth amplifier to your system or if you already have a amplifier and dont want to buy a new one you can add a bluetooth equalizer.
