signal 2 amps

[sjkreuze]

I have a 93 mercedes 300E and it has a factory tuner and amp in the trunk. I decided to replace the factory deck with an aftermarket JVC deck. This new deck has 2 RCA outputs so i thought i could use one of these to signal the factory amp to power the door speakers (its a 6 speaker system but the deck only has 4 outputs). As it turns out, the RCA outputs dont work on my deck and its too late to return it. Now i will have a mono amp and subs coming this weekend and i dont know how to signal them. I've done a little research and came across a 4-wire converter that will take speaker wire and convert it to RCA. Will it be possible to splice into my rear speaker's wire and signal both the factory amp and the sub amp? or will my rear speakers stop working?

I just figured i could do something so that i dont have to buy and install a new deck.

If you have a better idea, please let me know!

Thanks

Line out converter is the only way that i know of. i have one in my car with factory stereo and u sacrifice some sound quality. But there are sound processors that you can use to restore some of the clarity lost by the LOC.

how much sound quality will i loose exactly? haha. will it be noticeable only to a trained ear?
