Audio system & rims?

Hi....I have been trying to find info about changing my bose system on my 2002 i35, but i can't seem to find any thing.

I want to replace the factory 6disc changer with the kenwood kvt-911 in-dasc dvd/cd player with fold out 6.5 in. screen. I want keep all the foctory speakers and just ad a subwoofer bok and an amp. also there would be tv monitors in the head rest. Has anyone ever changed the factory radio?

The car audio guy at tweeter said i have to replace the whole unit. From radio, speakers and even wires. Is this true?

i cant find an aftermarket radio adapter to make the double-DIN a single. Do thay make then yet?

and finally, I want to put 20" rims on it. The rim guy said that 20's would affect my handeling and my mileage. any body have rims bigger than 18"?

With the bose speakers when you put in a new head unit one of three things will happen,
1. You will blow your speaker
2. You will fry the head unit
3. When you turn it up past halfway it will suond horrible
the bose speakers run at two ohms and after market head unit runs at four ohms. You can go some places that are able to rewire but otherwise you will have to replace the speakers as well and they will have to bypass the amps for the old speakers. Im currently getting a new head unit and adding subs and its a huge mess cause i have the bose in my car as well. it sucks

That's bogus .. I have a 2000 i30 with stock bose stereo speakers. The true problem with these systems, although they are pretty decent from the factory, is that if you go to change anything it is a nightmare for a few reasons (which can be avoided). The bose speakers each come with their own mini amplifiers, as to make the sound better, but this is a bitch for anyone looking to add a woofer and a new head unit. Currently, I have a Pioneer DEH-P6500 Organic Head Unit with a 12" Solobaric Kicker and a 800 watt amp I think. At first I had a crappy head unit, which would gather engine noise nicely, and never sounded quite right. I had the stereo worked on a second time, this time grounded perfectly, with a great head unit (the pioneer), and its beautiful. I am thinking of redoing the speakers, for the soul purpose of adding an amplifier to them, to make them sound sharper, other than that it's possible. As for the rims, I have 18's and have not noticed any mileage difference, probably because with the low-pro's the wheel is actually smaller than it was before. I might be getting 19's, I will let you guys know.

I have a 2002 I35 and ran into the same problem as you. Heres the deal, what's being said here is true but the main reason you can not change out the head unit in your car is Bose makes the systems our car's to work in line with the voltage of the security system and other accessories. Its set up like that so the electrical system will not have a voltage drop when the stereo is on along with other accessories in the car.(such as lights, defrosters, heat\ac, vanity lights, power rear shade, navi, etc.) clever but dirty nonetheless.

A second dirty reason is that Bose spends their money in designing the stereo's in a fashion that would prohibit individuals from changing out the components for aftermarket brands. This is so the value of the car can stay pretty decent. (which I30's and I35's have poor resale values until they are 3-4 years old.) This is done, because Bose is a trusted name in hifi sound thus adding to the cars value, sort of. (Note the unique waterfall flush design on the stereo in your car. Its not made like that to be pretty.)

I have went to many stereo shops, tweeter, circuit city and got the same repsonse. The best I could do to prevent totally ruining the cars value is add a sub and replace the amp for the rear deck dub in the trunk. Here's what you would need to do if you truely want to change the head unit and add a sub. Have a custom kit fabricated for the opening where the Bose is now and get ready to do a complete gutting of wires and capacitators (mini amps.) With the sub, just remove the rear deck sub, and have a box made that uses the opening of the existing sub as a port. Its best to work with a pro and have handy at least $3000-$4000 because custom setups aren't cheap.

Hope this helps

dont get 20s
