combox no audio

iwantaw335 · 04-24-2014, 06:03 PM

Hello, If you are missing the bombox will you not have audio at all?

I was searching and reading and someone mentioned that if your amp is out the only thing that is affect is the rear speakers and sub. Is that true?

I'm missing the factory installed combox and the amp is questionable and I have absolutely no sound.

Can anyone verify weather they have some after disconecting the amp and also disconnecting the combox?

If you have the L7 system, you need both components. It operates on a MOST ring system.

^^Kool. Thanks for confirming that if I have a Logic7 then I will need both the amp and combox for any type of sound.

Any break in the Most Bus Ring stops all devices on the Most Bus Ring.
More of the gongs come through the L7 speaker on the later model cars
so if the stereo doesn't work no gongs. Some of the early models have a
speaker under the dash for gongs . The details of the model years I am not
sure on.
