I heard that I can hook up rca ends to my stock amps and use it with my aftermarket hu. How am I supposed to hook up the cables? What goes in the middle and the outside?

 

anyone???.....

 

i dont think its possible..the sound would be terrible. Stock Bose amps are supposed to have the independence of the Bose H/U. But, if you want to give a try, here is the wiring for 98 maxima:

Left Front (+) Blue/White
Left Front (-) Blue/Yellow
Right Front (+) Brown
Right Front (-) Brown/White
Left Rear (+) Red
Left Rear (-) Green
Right Rear (+) Blue
Right Rear (-) Pink

The middle pin on the RCA would be + (positive) and the outter shield would be the - (negative)

Good luck.

 

Thanks for the information. It is really appreciated.

 

definetly wouldn't recommend if u are lookin for a system you can turn the volume up on but wiring up RCA's isn't neccesary at all. All you need to do is bypass the amp (tap into the wires between the amp and speakers) and your factory speakers will sound find at moderate levels running off of you aftermarket deck. Any ?'s on the wiring colors from the deck to match up w/ the above car colors let me know.

 

Thanks for the help.

 

Disregard the above post, as its evident that makdaddy doesnt know about Bose Your bose speakers are 1 or 2 ohm, and running these straight off the deck will make the deck cut out/go into protect mode.

Your Bose head unit sends an unamplified audio signal to the Bose amps. You have a few options:
1) Wire it in as you would a normal head unit and run a small risk of eventually burning up the Bose amps (not literally)
2) Buy the $50 PAC or Scosche adapter
3) Wire it with preouts. In detail: You have front and rear preouts, Each of these has a red and white plug, red being right and white being left. When you cut into an RCA that you plug into either of these, there will be two wires. So when you cut an RCA plugged into Front white you wire those two wires to white and white/black. Front red wire to gray and gray/black. Rear white wire to green and green/black. And Rear red wire to purple and purple/white.
4) Buy the Metra 70-7551 which comes with these RCA's so its all plug and play with no work for you

I was looking for something like this. This Bose shyt is giving me a headache and pising me off. I am going to look for it on the web, but do you recommend a certain place to buy it from? Thanks.

 

Circuit City won't have it in stock, so Im not sure Best Buy will either. Your best bet is to call around to local stores and custom shops and see if they have it, if not just order it online. Just ask places for the Metra 7551 amp integration harness.

 

Sorry I didnt get a chance to reply to your PM, but what Kevin said is exactly correct in option 3, although option 4 is alot simpler, Ive found Im one of the only shops that stocks the 7551 around here.

It is perfectly fine to do it this way, and not a problem at all or "sound terrible" as some people would say.

 

Thanks for the advice.

 

I guess it's all a matter of opinion. I enjoy my music, even at loud levels. I know and aknowledge how the Bose system operates...the H/U is connected to the amp bone, ect. Everything on the system is matched ohm and level wise.

All I can say is do what you think will work and try it. If it sounds good to YOU, then keep it. I offered my opinion and I think (hope) Pearl96Max was doing the same.

 

Actually theres really no opinion needed. It works just the same as using an "adaptor". No sound difference, as the adaptor does the same thing listed above. The Bose HU only sends a signal, same as a preout from an aftermarket radio. Impedance is Not in any way a factor here, nor is level matching. Hence the reason why Metra makes the 7551 harness.

I enjoy my music as well. So do the customers that I have worked for for the past 17 years. I do know just a little bit about the 12v industry

well all the information I have ever read concerning the Bose is how the speakers are a certain ohm and the H/U pushes out a voltage (level) that is not the same as most or all aftermarket. Such as this:

http://forums.maxima.org/showthread.php?t=401782

ect....and as for the harness, it only appears to be a splice without any electronics to adjust the signal..therefore you wouldn't need it if you knew how to wire tap.

I am sorry to have provided the wrong information however I did it with the understanding and intention that it was correct.

Could you tell me if that metra harness has any electronics because I have never seen it personally? I would like to learn 'correct' information on the Bose system, Pearl96Max. Thank you for your time.

 

I wasnt saying owned in a bad way, its all good, were all here to share and learn. I just enjoyed Dons saying I do know a little about the 12v industry.

As far as I know, the Metra 7551 doesnt have any electronics, although Ive never installed one, when doing this method I just do it like #3 of what I posted above.

 

Basically in simple terms, the Bose HU works just like an aftermarket HU with preouts. The Bose sends a signal, thats all. No power whatsoever.. IF you were to wire this up like a regular HU install (direct) it could and with time Will cause damage. Simply due to the fact that your sending power into an amplifier. Similiar to that of plugging an outlet into another outlet if you will.

When doing it the way that I do or using the Metra harness, your simply changing from one signal (Bose) to another signal (aftermarket HU). Your not really changing anything. In fact, depending on your aftermarket HU, you could stand to benefit from this method.

Feel free to ask anymore questions if youd like.

 

As always, I thank all for the help.

 

Yes, I understand all that. Of course if you wouldn't put a high level source into the Bose amps which are designed to only accept a low level. And thus thats why I asked the question concerning the harness because all it appears to do is take the speaker wire going to the amps and adds RCA's to it without doing anything else. I believe I got my answer. However it does not explain why other people on the forum have other opinions on it and the PAC ROEM-NIS2 was designed.

The ROEM-NIS2 has variable controls on it so that the voltage of the signal can be adjusted. From the information that I know is that the Bose pushes out a voltage that varys between 0.7v and 9.0v. Most 'BestBuy' aftermarket stuff don't even go that low nor that high. Seeing as the factory amps do not have their own gains (unlike aftermarket for matching with your H/U, ect), I do not see a way of adjusting this using the Metra kit or tap method.

Yes, you are reading this, going, GOD, he is nitpicking and yes, I realize that. I definately retract my statement about "sounding terrible". lol I jumped to conclusions without trying it myself, memphis.

Levels in my opinion are mostly over-rated but when replacing my equipment, I would want everything to match perfectly....thats just me.

I thank you PearlMax for your help. And no prob memphis about the info I gave. Hope everything works out well for you.
