[QUOTE="ScuL, post: 8136367, member: 656055"] Hi guys I already have an existing car audio system that I took out of my old vehicle when I traded it in for the same model yet brand new. Previously I had replaced the factory headunit for a Sony HU (4x55W), in the doors I had 4x 180W Pioneer and 2x 28mm tweeters in the front. I connected the HU through an RCA lead to the amp (good old Sony XM-1S) and hooked a subwoofer to that. I had the speakers wired directly to the HU. In the 2013 version of my car there's a built-in sat-nav system which will be disabled when the factory radio is removed. Because of this I would like to install my old audio-system yet hook it up to the [B]factory radio[/B]. Unfortunately the factory radio does not have any RCA-outputs, it goes straight to the speakers. Now I'm contemplating the following setup: -> Tweeters directly connected to the radio -> Front-speakers -> loop from front door to boot, into 4 channel amp (front) and back to the door -> Rear-speakers -> loop from rear door to boot, into 4 channel amp (rear) and back to the door -> Sub -> on separate amp. This means I have to purchase an additional 4-channel amp that can take high-level inputs. My problem is: -> I only have 4 speaker leads (left-front, right-front, left-rear, right-rear) and have to feed 2 amps with these. What is the best approach? A. Split the speaker wires directly behind the HU and use a high-low (RCA) converter? B. Run the speaker wires all the way to the boot and attach them to both amps (1 to the 4 chan and 1 to the sub-amp) Alternatively -> are there any amps that also have an RCA OUTPUT? (So that you can loop the signal from the 4-chan amp into the sub-amp)? I browsed lots of websites and found that 5-channel amps exist as well (which means I could get rid of the old sub-amp), however it looks like I struggle to find a model that provide the power I require for the sub (it's 1500W RMS/380W nominal).
