Yepp thx got everything done I just tapped the stock wiring just ran the red/green to the crossover and made a new 16awg wire for the tweets left the rear tweets bose and threw everything in works damn good and sounds Amazing compared to those paper bose speaker with no subs only thing is it took me and a a friend about 8 hours and I didnt doc $hit like I said I was. mostly because I was being picky about where to run wires etc. but all is good now loving my new bumping system. still feels like I may need the Lci6 line out converter thing because the fronts seem like they aren't getting enough juice they bump nice and clear but it feels like they got more in them.

For guys in the future that dont want to run new wires just tap the bose wires and run a crossover and install new tweets and you should be good to go thats all I did.

thanks for the help guys!

P.S. solder all your connection take the time to do it clean and right I did (minus running new wire.)

You get what you pay for. Infinity makes great stuff. Boss, Pyle and rando-nonames do not.

Side note, few weeks back I had a customer bring me one of those no-name eBay Chinese Android units to install in...a Silverado I think? $130 in parts + $100 in labor. Unit turns on, shows the splash screen....and never anything else. Ouch. I felt bad for the kid, but hey, not my fault. All my connections are soldered and heat shrunk. Unit gets power fine. It's a software issue my man.

Hey d_extreme how'd your head unit work out? I really only want a tablet as a head unit, with a 3.5mm out to some kind of amplifier that can then split the audio out to my 9 BOSE speakers.

I hope anyone could help me

i want to change my headunit, i will purchase some model of pionner with carplay (right now i dont know yet what model i will purchase)

i have a shinka 2006 with bose sound system, every thread i read, and every video i saw all the rx8 was an standar sound system, with 4 speakers (2 fronts 2 rear)

Hey all,
I've spent several hours reading and searching through posts and I haven't been able to find a truly good avenue to take to resolve my alternator feedback I'm getting through my speakers.

I have a Bose system, I've removed the OEM deck, and I have a Metra installation kit installed. After installing all of that according to the Metra kit instructions, there was no sound, but also no alternator feedback (basically no sound output at all). Then I read this:

EDIT:Ahhh I guess Carbon answered you in the other thread. Pink/black it should be.
And hooked up the ACC +12v to the pink/black wire. Now I am getting sound, however with the alternator feedback (e.g. high pitch noise which increases with RPM). But I've also read posts like this:

Which suggest that the +12v to the Bose amp in back (pink/black wire) should actually be the constant 12v, not switched from the ignition. I'm thinking that in the OEM deck perhaps the constant is used in order to avoid alternator feedback? But at the same time, I'm not confident that the battery won't drain while the engine is off given what FoxRacer said.

Does anyone have a bigger picture of this whole situation now that we're 10+ years later?

P.S. No, no wires are touching each other or ground/chassis.

Turns out that the Bose OEM deck only sends 20mA (versus 20,000mA/20A) to the Bose preamp. Moral of the story: pink/black wire is a, "remote on" that doesn't need power fed to it, only a very weak (12v/20mA) signal to keep it powered. I'm guessing the feedback in the sound is a result of too much current being available in the signal wire (pink/black). Will update when I've devised a closer replica to the OEM deck.

(Really it shouldn't matter since devices only consume as much amperage as they need, but as others have pointed out, the Bose system is crap, so who knows how the ICs look inside of the amp.)

EDIT: Nope, wasn't that. Next best guess is that it's that the RCA wires are bundled into the stereo harness from Metra (since normally they're speaker level [e.g. post-amp] wires). Bought some copper tape shielding and I'll apply that to the wires in addition to separating them.
