i read the diy for adding sub and amp to the stock bose headunit but i didnt get the part where you splice from the bose amp?? the guy that is going to install for me said he is gonna tap from the rear speakers and use a hi-low converter, is that the wrong way to do it or am i sopused to tap from the bose amp???? someone help

 

he is doing it correctly, he will most likely install what is called a periphreal linear inverter, which basically on one end will splice into the speaker wire for the rear speakers, the other end will have rca female plugs for the amp. Leave the factory amp in tact, there is no need to mess with it unless you want to remove to get rid of dead weight which is that because it and the speakers that it sends a signal to suck big fat donkey nads. At least in my car they do

 

this sounds right....

It's not a good idea to tap into the Bose audio signal ALFTER it goed through the Bose amp (like at the speakers) because the Bose amp is where all the bad equalization happens. The Bose amp will decrease the bass as the volume increases, which is probably not what you want when adding a sub.

your installer wants to take the easy way.

 

^^Gilley's right. Plus, it's not that much harder to tap into the Bose wires.

 

I felt the AMP was easier to get ot that the rear deck speaker wires. There was hardly any room up under there. If I had to do it all over again, I would have been tapping into the wires right before the AMP.

 

so the correct way to tap into before the bose amp? which wires?? am i still going to need a hi-low converter, sorry im kind of a noob when it comes to audio

 

here is the diagram....I don't know what color "L" or "P" stands for.... purple? What does L stand for? Sean, throw your two cents in....

L = teal?

I have posted several times what I found to be the wire colors but I can't find them at the moment. The board is slow.

 

that would be very helpful if u can

 

someone help me i have the factory nissan ipod connection when i hooked it up to the bose amp it was alot more clear louder and more bass, some people are sayin to tap before the bose amp and some people are sayin its fine to do it after the bose amp for example the rear speakers, will the quality of the ipod integration not go into the subs if i tap before the bose amp? hopefully that made sense, when i hooked up the factory ipod it sounded nice clearer and more bass, i want to still have that, if tapin before the bose amp will the quality of the ipod not go into the subs? someone please help

 

Here's the DIY:

the diy doesnt answer my question, i connected factory ipod connection sounds alot better, will tapping before the bose amp have any effect? wouldnt it be better to tap after at the rear speakers? Any one have the factory ipod connection with stock headunit with sub and amp? did you tap before or after the bose amp? anyone help??!??!

 

The iPod connection is a separate issue from adding an amp. The iPod connection feeds into the radio. Adding an amp happens after the radio. As I stated in my PM to you, it is better to get the audio signal before it goes into the Bose amp, which where all of the bad equalization takes place. There are a lot of threads that recommend tapping into the audio signal before it goes into the Bose amp as being the preferred method.

IMO, I think it sounds better when I have control over the amount of bass from the audio system rather than being at the mercy of the Bose engineers when designing a stock system where the two bass drivers are 6x9's instead of a true subwoofer or two.

Also, whether the installation sounds good has a lot to do with your installation.

So tapping into the audio signal before the Bose amp will have the best potential for the best sound using the OEM HU.

 

Looks like the "L" = Light Blue (Teal) and "P" = Pink. Checked my wiring today.
