Automotive line out converter for home theatre use

[accobraman]

Thank you all in advance for your input on this subject.

I have found many Line-out Converters used by the automoble audio industry that can be connected directly to a car radio/amp speaker terminals. Or, connected in parallel to existing speakers. When connected it converts the higher voltage speaker signal to a pre-amplified milliamp/volt signal that can be connected to another amp's Line-in RCA jack.

However, I cannot locate a similar converter to use for home audio applications. What I'm trying to do is not common practice, but is would please me to no end to find a solution.

I have just installed a new home theatre system and the new Yamaha
RX-V757 amp has two additional jacks for left & right front Presence speakers. I do not have any more room to install two more front speakers. So I would like to use the speakers that are built into the Samsung DLP TV. To do this I need a converter to convert speaker voltage to pre RCA inputs. Any reason not to use the automotive line-out converters for this application? Comments would be much appreciated. Thank you!

In all honesty, I think it would be a waste of your time. The speakers built into your TV are very low quality and wouldn't be able to keep up with the rest of your system (which I assume is pretty good, judging by your receiver choice). I'd say scrap the idea, but that's just my opinion.

Thanks!

Appreciate your comments, but its that or no speakers at all.

I'm willing to compromise and accept the Samsung amp and speakers for the Presence channel speakers. They wont have to work too hard and only get used when the media/movie has the Presence option recorded.

I completely agree with Jaxvon. You would be better off not using your tv speakers completely (while using your stereo) because few tv's have speakers capable of even keeping up with a good system. The RCA converter is a good thought, but it is not pratical for your aplication. The converter is ment for use in car audio head units without RCA outputs using the 25-55 watt speaker input and converts it to a variable gain preamplified RCA input. Which going to a powerful amplifier can be a very good thing, but the tv has a very small and very cheaply built amp. Your reciever is about three times the input of a car head unit, when you put that into your tv you might just get a nice smoke effect to add to the movie enviroment before you have a $3000 bonfire. I personally think that you are not missing anything by not having your presence speakers. I still think that 5.1 is where it's at. Good Luck. Happy Listening.
