Which Speakers To Use

[kvrr79]

Hi,


I have 1994 325i Convertible. I want to replace my rear speakers with

MB Quart 6X9s(which I have) or
51/4 Infinity ref 5000CS or
MB Quart 51/4 speakers.

I read from the forum posts that Mb Quarts may need an amp. As of my understanding my car does have an factory installed amp.

1. Does my car have a AMP installed ?

2. What is the rating of this AMP?

3. Won't this be enough to drive MB Quart 51/4?

4. If I install these speakers. How to connect the cross overs. As of my understandning the cables are crossed over at the amp or head unit. How do I connect the new ones ?

5. I have MB Quart 6X9 speakers ( I am trying to fix them in the rear panel. Today I have opened the rear panel. After opening it I figured that I can fix them directly without the base grill.). If I use this how to connect to the 4 wires (the car speaker connector has 4 wires (2 for speaker and 2 for tweeter).

6. Does the 6X9 also need an AMP ?

Thanks for you help inadvance. Sorry for too many questions.

Thanks,

1. Yes.

2. Crap. (15-20W RMS range would be a high estimate)

3. No. Also, rears are 4", not 5 1/4".

4. You would have to install a new amp. If you went with the factory amp (which would be a waste of money to do so and use those speakers) you wouldn't need them because of the internal amp xover. With a new amp wired in close promimity to the old ones location, simply add wire to connect the amp channel to the xover, then cut the harness of the factory amp and use the existing wire for the mid and tweet.

5. The mid wires go to the 6x9s pos and neg terminals. tape off the tweet wires.

6. Yes.
