Connecting external speakers to tv
Have a question about connecting my HDTV to better speakers. In my 2004 Jayco motorhome, I have replaced my old tv with a new HDTV. However as most of you know the speakers in the tv are terrible, e...

Your DVD could possibly use the built in DVD/AM/FM unit to send the VIDEO to the TV or receive analog audio from the TV.
This will take some detective work though.
Most Car stereo DVD/AM/FM units have analog Composite video output which was intended on feeding a second video monitor for kids.
As someone else pointed out, much of the newer TVs no longer have any analog inputs for video, instead you will find only Digital HDMI connections which one cable contains digital audio and video signals. By the way, HDMI connections on the TV are INPUT ONLY, they do not send A/V outside of the TV (helps cut down on "piracy" potential of HD video).
To get analog video from external sources into your TV you need a video "scaler" which converts the analog composite video to digital HDMI.
Now, if you are looking more to route the TVs TUNER AUDIO into the external DVD/AM/FM unit that would require the TV to have some sort of OUTPUT connection like a analog headphone jack or a digital OPTICAL audio output. It would also require the DVD/AM/FM unit to have an analog AUX input (some do, some don't.
If you have headphone output on the TV and analog AUX input on the DVD/AM/FM unit, you are pretty much set, just need a shielded cable to plug into the TV headphone jack and plug the other end in the DVD/AM/FM unit. One word of warning on this, you can get something called a ground loop hum due to differences in grounding potential between the TV and DVD/AM/FM unit.. If you get a hum or interference noise in the audio, you will need to buy a transformer based ground loop isolator to put in between the two.
If TV does not have headphone jack but has optical digital jack you will need a optical to analog adapter to make it work.
If TV does not have any audio out jacks like headphone or optical, you are pretty much out of luck unless you want to break out the tools and crack the TV case apart to bring the speaker wires out of the TV..
Not for the faint of heart and not for the amateur, this is an advanced electronics thing because you can easily break a lot of things that you cannot buy new or used parts for if you do not know what you are doing..
