I have installed an aftermarket HU and now i am thinking about replacing all of my speakers. the only thing that would stop me from replacing them is if i have to rewire the entire car. is it possible to bypass the amps and use the present wiring of the car with aftermarket speakers and HU? are there any guides on doing this? sorry for the repetiveness of this thread, i'm sure ive seen things about this on other threads i'm simply trying to put it all together in one place.

 

Match up the wires in the doors and going to the rear deck with whats behind the headunit by color, and then use those, OR just run new wires, it's really easy in the 4th gen.

 

I attempted to get a new deck for my car but they guys at ultimate electronics and best buy said they wont do it because all HUs only do 4 ohms and the Bose are 8 ohms. You can do it but they say it sounds like ****. Is this true? I can only imagine the speakers being louder at lower levels and thats not a big deal.

 

They're shooting **** up your a$$. Bose is 1 ohm not 8 ohm and you can simply run a metra 70-7551 in place of a typical harness and get a new HU installed.

 

Oh, right on! so the metra 70-7551 is the only harness you need?

 

Yup and I think an antenna adapter.

 

yeah i had the same experience, they have no idea what they are talking about. you just need an adapter for it. i got mine off crutchfield for only $20 if you bought the HU from them, i think it was $40 if you already had the HU.

and they send you the antenna adapter, and all the other things you need for install. i know i sound like an ad rep, but i personally would shop with crutchfield over anyone else (aside from a private dealer), great customer service, and they generaly send you all the extra parts that you need for an install that bestbuy charges you out the a$$ for when they install it.

 

is there any disadvantage to just matching up the colors? i kind of want to use the existing wires incase i ever decide to sell the car and reinstall the bose speakers.

 

Not really...

 

You can use the aftermarket HU with the bose speakers if you get the proper harnest. You want to use the RCA jacks that come out the back of the HU into the new harnest. Dont even try to use the powered Speaker leads to the existing harnest.... wont work.... Hope that helps.

 

And that harness would be the metra 70-7551.

 

Yes. I replaced the Bose system with aftermarket head unit and speakers and re-used the stock wiring. As others have said, all you need is the harness for the radio ($20 bucks) and an antenna adapter ($10 bucks?). At the doors and rear speakers, you just remove the Bose speaker/amp, cut off the Bose speaker connector and hook them up to your new speakers. Get a Haynes manual. It has useful wiring diagrams for the entire speaker system to tell you which color wire is what.

 

does any 1 know were i can get original bose?? sum 1 stole mine

 

if you are looking to buy anything the classifieds is a good place to start. i may have a head unit and speakers soon, im not sure if i want to sell them or not but let me know if you are interested.

 

ive already got the new HU installed and i had to buy a special harness for it to work with the bose speakers so i dont really want to buy another harness if i dont have to. on the curent harness each speaker output has a screw wich can be adjusted to limit the output from the amp, so my question is if i just turned it all the way down (so it didnt have any limit) would that work just as well as getting a new harness, or is it always going to have some impedance?

 

i am interested the ones that i have on there suck big time some 1 stole mine so if u do want 2 sell them ill take them the head unit too

 

Doh!!! I chucked mine in the garbage!!! It still worked. Doh

 

ill pm you once i replace my speakers, could be a while depending on the next paycheck.

 

dont worry i can wait

 

Get it back!!! haha i woulda given ya at least 50 bucks

 

Someone in here write a real tutorial and i will stick it.

 

I think it's in FAQ's?

 

Audio or here? (D@mn I am lazy today)

 

what do you need to tutorial to be on? im the king of maxima bose/ non bose stereo installs

 

^^^^^^^^
Bypassing the Bose, with wire color codes.

 

so, you mean Aftermarket HU with Aftermarket speakers? er?
whats the setup?

 

To re-use the stock Bose wiring with an aftermarket HU and aftermarket speakers.

 

easy as pie... gimmie some time tho. Its friday and im at work... not working... dont plan on doing anywork untill monday

 

honestly its not worth trying to bypass the amps, just rewire the car. I did it over winter break and it took me a grand total of an hour at most. The max is really easy to rewire. Perhaps the most annoying thing was trying to get wire through the rubber dams in the doors but then i just ran it with the wires going to the window switch. The stock wiring SUCKS! Its like 22 gauge wire thats 10 years old by now. Do yourself a favor and run new wires.

 

can you use the stock speakers with a aftermarker HU? and will it sound good?

 

Yes it may or may not sound good.

 

i have it right now. alpine unit with bose speakers. its decent so to say but this alpine in another car will sound better.

 

so it would just be better to keep the stock HU?

 

oh hell no.

 

what is better about a aftermarket one? the stock one sounds really good. i dont really know much about radios.

 

Just get rid of the Bose...run new wiring its not that hard i just did it to my car 1 week ago...It sounds better you'll be happy u did it trust me.

Just my 0.2cents

 

any sugguestions on a new HU and speakers

 

What do you after market HU people do with the extra room with the step from double slot to single slot? I had an MX6 w/ an after market unit (same situation) and always hated the gapping hole in my dash. I want to avoid that on my Maxima, its much nicer.
Thanks for the wiring wisdom, I'm probably doing this soon as my Bose unit now no longer plays CDs.

 

well there are two options. right now i am looking at a radio that is a double slot that will use the whole space (kenwood dpx302) or they make a dash kit that takes up the extra space left from a single slot and makes another compartment out of it.
