Newbie needs help with RCA Output ?'s

[temeculaX5]

Hello all,

Trying to figure out how to add RCA outputs to a factory system.

I saw the article on how to add a sub amp, but it didn't specify how to add the RCA jacks.

I have an '02 x5, non-dsp, non-nav, no changer (but has DICE plugged in). Pretty basic.

Any input is appreciated.

You should already have RCA outputs from your radio (assuming you have an IBus vehicle).

Look on your radio and you should see a square connector set that looks like the attached picture. The 4 wires at the bottom (Yellow w/ Red, Blue w/ Red & 2 Brown w/ Orange) are the outputs to the amp. Since you are non-DSP, they will be 5V balanced RCA's. You actually probably have 8 wires in this area. The Yellow are the Left + and the Blue are the Right +. Red means front. Since I don't have the other wires I can't tell you the stripe color for the back Each wire has a corresponding Brown w/ Orange that is the -.

Wire them in, or if you want, there is an adaptor available that makes it a lot easier and keeps you from cutting the stock wiring. See my blog for details.

Good Luck!

Well you can go to either a local car stereo shop, I think radio shack, or best buy what ever is around you, and ask for a PAC SNI-35 here is a link to an e-bay auction to get a look at it http://cgi.ebay.com/PAC-SNI-35-2-CHA...QQcmdZViewItem


I added an amp and sub to my girls car, basically what I did was found the rear speaker wires spliced them together with the front speakers and put the adapter straight to the rear left and right wires, went from adapter to amp to a 10" fosgate and it pounds nicely. Granted you will loose fader controls unless you want to put all front speakers on the left front, and rear speakers to the front right then your balance will act like a fader,
hopefully this helps

Hi D,

Thanks for the help... I greatly appreciate it!

I will post again to let you know how it goes.

Warm regards,

Why did you combine the front and rear speakers? I'm lost in that sentence...

well, the car in question was a 05 celica with the oem headunit no external amp from the factory, and it literally had four speaker wires off the back of the deck. It had two tweeters in front, and midrange (which had factory crossovers for the tweeters) and then rear speakers, so six all together. I first just tapped into the rear speakers to run to the amp, and it sounded like crap, the sub was barely making any noise, and the rear speakers were overdriving badly, I then disconnected the rear speakers all together, and between the front speakers and the sub it sounded great, so i added the left rear speaker to the left front speaker, the right rear speaker to the right front speaker, it sounded great, crystal clear front end and a pounding sub, but had no fader control, so got a wild idea to put the front speakers on the front left and the rear speakers on the front right to have fader controls, I don't usually mess with left and right balance. And the rear speaker wires to the amp were controlled via the true fader control to reduce the bass when it wasn't wanted. It was the one way that made her car sound very clear and none of the speakers were overdriving.
how would you wire it up?

[DouglasABaker]

So you have 2 way components in the front and a pair of full range in the back. Tapping the full range in the back somehow gave you a degraded signal to the full range speakers which means you did it wrong. Not trying to be smart, but if you tapped in and wired them correctly then there would be no change in sound to the full range speakers.

What you did initially was the correct way to wire them, something must have gone wrong (bad wire tap, shorted wire, I can only guess).

I do know that by combining the signal from the Left Front and the Left Rear you have now created a possible short or feedback loop into the head unit.

Your next sentence seems to indicate that you then decided to wire all 4 of the front speakers to the left channel and both of the rear speakers to the right channel with the sub amp on the rear channels. This will give you a left-right instead of a front-back soundstage, but hey, if sounds good to you, go for it!
