Rear Speaker Setup

I am going to be upgrading the components in my 2000 328 non-HK sedan up front (already replaced rear deck with stealthboxes) and I was wondering about the rear tweet setup. Is it ok to leave them stock or will that vastly degrade the sound quality? If I end up replacing them, what is the best bet, just get a pair of aftermarket tweets and hook them up to the same amp as the component system up front?

edit: using stock HU and stock amp to drive all speakers... JL 250/1 driving the stealthboxes off of the balanced line from the HU.

Just a word of caution on upgrading your front speakers to the factory amp.

I have 2000 328Ci non HK. My intent was to upgrade the speakers only as I already had them from a previous car. The stock speakers use the cross over in the factory amp, and the impedence is imbalanced on the stock speakers, the woofer is 2 ohm, the mid and tweet 8 ohm. You will need to use the factory crossovers instead of the crossovers that come with your upgraded speakers, and you will likely have to get some power resistors to place in parrallel/series with the speakers to bring everything to 8 ohms so the speaker output from the tweeter is at the same level as the woofer. It works okay, but I couldn't get the volume output quite right, so I ended up adding an amp.... didn't like the VEN4 so I added a new head unit.... needed more power so I added another amp for the fronts.... now I have noise.

Not sure if it ever ends

I am using an aftermarket amp, so that should bypass the crossover problem. Also, did you leave the factory midbass speaker that is not replaced in a 2 way component system? and did you leave the rear tweet running off of the factory amp?

On the fronts.... No I did not leave the factory mid in place, I believe this will cause a couple of problems.
1. The 2 way components are meant to be played as a system, If you left the factory mid, you would just be overlapping sound in the middle from a presumably pourer quality/sounding speaker, thus not getting the best sound you could get.
2. How would you cross-over to the factory mid, use the component cross over?
3. Your after market components are probably 4 ohm, the factory mid is 8 ohm... so the factory mid, and the aftermarket components would play at different volume.

I would definately not keep the factory mid up front with the new aftermarket 2 way components.

On the rears... I just left the factory tweet dead. I mounted some 4" two way components that I had in the rear for fill. I am now thinking I will remove them so the bass can get into the cabin from the trunk, not sure I want to cut out the ski pass. If I were you I would put the components up front, the stealths in the rear, and leave the rear tweets dead. I think that is what most people using the stealth boxes do.
