Hi All,

Just wondering if there are any car audio speciaists here.

I'm repacing the broken factory headunit in our car with an aftermarket one. AFterdoing some research I found our car has a factory instaled AMP under the passenger seat. How does one go to connect an existing headunit to a factory amp.

i.e. each speaker from the existing headunit to the amp has speaker +. speaker -, and a shield. so there are 4 sets of those (FL, FR, RL, RR). The headunits only have L and R pre-amp out which obviously have only signal and shield.

I can do some trial and error but keen to hear a professional's opinion.

Cheers
Johan

it always helps when you include details like make/model/year of car and information about the head unit

Headunit I have not bought yet, but all of them have standard RCA pre-amp output.

Car is honda odyssey 2003. However, not much to find on audio details on the net. I have found the pinout of the radio. http://nzhondas.com/i-c-e-security/156652-rb1-odyssey-misc-information-thread.html

Cheers,

It would most likely be balanced audio. Which would have been done to stop it from picking up interference. http://en.wikipedia.org/wiki/Balanced_audio

A bit of a late reply but I thought I'd give a quick update. I ended up ripping out the factory amp and running some wires from the AMP to the headunit. It' relatively short and not too hard to get to.

Works like a charm and sound really good.

Next step is hooking up the steering wheel buttons.. already tested it just have to find the time to wire it in.

Cheers
