OK,if you us 6x9 in any car that has a good staging set-up like a 3 way kit in the front, you will pull your staging away from the front of the car.....never us a 6x9 in a car....rear speakers in a car ahould go no more then 5.25...

Find a wreck that had HK sound option in it, Im almost positive the stock rear
speaker inclosures had 6x9's in them used as subs.

That's true for the e46 HK sound option, unfortunately the e46 HK audio uses a non standard 3ohms. Also sounds horrible... only mod I've done to the e46 is upgrade the stereo. That stock HK system is horrid.

Nope... I've got both, e36 and e46. Up until 96 e36's used 4ohms... 97+ were 3ohms. But if you have a 3ohm system, you also have a 5.25" and a 1.1" tweet in the rear shelf in a baffle box, not a sealed box with a 4" and 1" tweet.. The enclosures have different mounting points in the e46, the e36's use a single screw and a tab, unless you drill out new holes and manage to keep a tight seal.

As Paul Christians said, 6x9's also sound horrible... if they didn't, that's what home stereos and studio monitors would use too. 6x9's were invented back in the 60's when GM didn't have any room for larger speakers, so they made these 6x9's to get larger speakers in there. Unfortunately, the trend still exists today. He's much better off with 8" subs as Paul said, firing up into the old holes. This is what we're doing in the Rx8... removing the 6x9's and mounting two JL 8W7's under there instead. The hole diameter is almost identical, just have to leave a good 3" space for excursion.

If he doesn't have that kind of money to spend, then the Soundsplinter RL-i's are a very very very worthy choice, most would say even better than the 8W7's for a fraction of the cost, and matches up to specs and frequency response too. more info: http://www.soundsplinter.com/rli_ign...r_drivers.html

What these guys said. Never, ever use 6x9's if you care about sound quality. But then again, I swear 90% of the general public can't distinguish between good sound or bad (or have just never heard good sound before, no reference point).

BTW Justin, do you know if E46 non-HK speakers are 3 ohm also?

True... I've heard people argue that the stock e36 stereo sounded good. :/

The e46 non-HK door speakers are 2ohms. Not sure about the rest of the system. (in the e36's in 94-96 the door speakers are 8ohms, and the rear deck speakers are 4ohms. I'm not sure if they did something weird like that with the rear deck speakers on the e46 non-HK audio)

This is from the non-HK e46 door speaker:

think about it this way,a normal car speaker is said to 4ohms right,wroug it is 3.2 ohms,so if they sa it is 3ohms,it will be 2.8ohms.Why they do that they run the in series-paralle....but this maybe too much some to think of.....

Really 3.2? To what happens when you wire down.

I know cheater amps for example say they make
50w at 4ohm
100 at 2ohm
200 at 1ohm
(example)

So can switch up the wiring for different power, and wouldnt a 3ohm speaker be useless with amps like this?

But then again I guess you would not be using a 1ohm stable amp with stock speakers..

Well, wired in series they would be 1.5ohms. JL amps are stable down to that, so I guess that's the only option. But yeah, if you're going to spend that much money on a good amp you should be replacing the speakers anyways.

Stupid all-or-nothing approach to upgrading new BMW systems.
