I have a 93 Lexus Sc300 with the stock premium pioneer stystem. i am going to replace the speakers...and hardly know anything about car speakers. ive been trying to get these questions answered for a while.

1) what is the dimensions of the stock speakers?

2) what are the largest size speakers and the stock sub thati can fit in each loacation without cutting?

3) should i go with coax, 2wy, 3wy, or full range?

thanks! =)

 

4" in the front doors, .75" tweeters in the front

4" in the rear deck

10" sub in the rear deck.

You have to cut to put anything bigger in there. I really wouldn't reccomend putting a sub back in that spot....put a small box in the trunk with a 10 or 12 and leave the factory sub out for airflow. It will sound MUCH better that way.

You can easily cut/break the plastic front speaker mount boxes in the door to fit a 5.25" speaker, I've got pics of the entire process when I did it, only took about 20min. per door.


As for speakers to use....it's all up to you. I would get a componet set, and mount the tweeters and minds in the factory spots....keeps the factory look. In the rear it's up to you, I don't even have rear speakers, just subs in the trunk. I had some Alpine's in the back, but they got blown to sh*t from the air from the subs. It sounds perfectly ok without a rear stage....the fronts are plenty loud

Wiz,

Can you send me the pics of your front door speaker modification?

I can't belive they are 4" speakers. How in the world they got 4" speakers to sound that good is beyond me.

I also plan to change to 5 1/4" speakers like yourself in the front doors but I would like to keep the factory amplifiers and/or crossovers. Do you know where those are located in the doors? Are the crossovers all passive? Or do they have electronic crossovers and seperate amps for the tweeters and 4 inch woofers?

Any info would be appreciated.

I'll send you the pics soon as I get home....I don't think I've got 'em on my laptop here.

The factory crossovers are passive, and they're located inside of the speaker-box in each door. When taking it apart you'll see what I mean. The amp for them is under the CD changer in the trunk (well if you have Pioneer, not sure about the Nak system)
