Front Door Speaker Question

[ut_cougar]

I realized something after looking at the door speaker install instructs online... is their just a 5.25" driver in the door and thats it? I never noticed anything about a tweeter or anyone replacing a tweeter in the couple of online instructs I saw that people made? (oh and this is in regards to the upgraded system with amp etc obviously) So someone tell me if I'm correct in my assesment- There are (2) 4" speakers with (2) .75 or 1" tweeters in the DASH... then there are (2) 5.25" mid-drivers in the DOORS...? correct? I was planning on buying a component set for the doors but looks like I'll have to figure somewhere to put the tweeter that come with the 5.25" components OR just buy the 5.25" drivers alone. (I'm trying to keep the system as stock as possible so no big upgrades, etc)

It's two 4" Dash Speakers, two .75" Tweeters in the dash, and the 5.25" woofers in the doors. You can boost the door speakers up to about 6.5-6.75" if you don't mind making new baffles.
Also, I don't see why you couldn't use coaxial speakers in the doors, but I am no audio expert.

Okay, thats what I just realized.... there are no door tweeters so those would be add-ons if i changed out the doors speakers because you just can't buy decent 5.25" speakers unless they are in a component set... and i think the tweeters would be useless because having the set in the dash AND the set in the door would just be too much highs IMO. Now my main problem is the dash speakers since I need to replace the dash's 4" components with new ones and I don't think I can run any of the 4" compenents currently on the market with the stock amp, right? The stock amp is pushing 40 watts to each of the front dash compenent sets and all the 4" compenents on the market are 4 ohm speakers. There area few sets that are 2 ohm for the 5.25" components so my doors will be nice and loud and the power will be sufficient but the dash speakers will be be running off the same wattage but at 4 ohm resistance. This is where my problem lies. The only thing I can do is replace the dash speakers with coaxials and leave the tweeter spot empty but I really don't want to do that since compenents sound so much better. The other thing I thought about was running the coaxials in the stock 4" dash spots but also running the tweeters from the 5.25" doors all the way back up to the dash somehow and filling in those empty spots where the tweeters used to be, but then I have 2 sets of tweeters right next to eachother (one on coax and other running from the 5.25" doors). I don't want to cut or drill any holes in the doors to mount the tweeters from the 5.25" doors so that is the only option or just leave the tweeters out i guess? (If i leave the tweeters out of the 5.25" component sets then will more wattage run to the 5.25" speakers since the tweeters aren't there taking up power?). The main pain in the ass is because I don't want to change the stock amp or add any amps, etc. Anyone have any advice on what to do for just a stock all around speaker swap (without changing anything else)?? I'm told not to run 4 ohm speakers off the stock amp because of the lack of power otherwise i would just run 4 ohm speakers all around. anyone here running aftermarket 4 ohm speakers all around off the stock amp?

I can't answer your question, but you might consider editing you post into paragraphs. It makes it a lot more friendly, and people will be willing to read it if it is easier to read, and possibly shorter. All can say about the tweeters is that .75" tweeters in the car now are probably going to be better than the tweeters you get on a 5.25" coaxial.

please edit your post in paragraphs. It's been a long day and my eyes are fuzzy so I can't focus to read all your questions. Anyhow, you can use coaxials in the doors, but there is a filter in the amp that only sends lows to the doors. Unless you also change the amp, only wire up the woofer part of the speaker (you can eliminate the crossover if you'd like)

Regarding upgrading the doors.... plain and simple, just make baffles. I tried swapping 3 sets of 5.25" to replace the stock drivers. 2 sounded worse than OEM, one was maybe as good as........ Crux of the problem is 5.25" speakers by their very nature, w/out boat loads of power, simply cannot produce any reasonable low end due to size. Trust those of us who've been down this road, make the baffles (very easy to do) and put either 6.5", 6.75" or 6x9" in. With the right combinations, you can keep the stock amp so everything still will look stock but sound great (including w/ the dash drivers). All the mods will be behind the door skin and grille.

Lots of info on this topic (including DIY guides and a baffle template ) are available here, on renntech and ppbb. Use the search feature and you'll find pretty much any answer you need.

Good luck

okay 3 questions- 1. are the DASH speakers 2 or 4 ohm impedence?
2. you said you switched out 3 sets of DOOR speakers, what was the set that sounded equilavent to the stocks (brand/model)?
3. were the sets in the doors that you switched out 2 or 4 ohm?

the reason why i ask is because infinity has a very nice component 5.25 set in a 2 ohm set-up...i was told by a crutchfield rep that they are perfect for porsches and sound much better.

i don't want to do the baffle because for one i'm trying to keep cost as low as possible so i want to do all the work myself... (wait before you tell me i can do it myself, read on)

i know i can easily do it myself, it would take a couple hours and sound better, etc. etc. .. but i am just worn down to the bone guys, i'm a 3rd year medical student and there are only 2 things important in life to me right now (other than family)... first is trying to save money, second is trying to use the few minutes i get everyday to relax, or honestly anything but sit in a garage and work on my car, cutting wood, going to home depot for wood, etc (now i hope you guys notice how the two most important things in my life pertain to this speaker upgrade?)

i would surely do it if someone would charge me $20 but after pricing it here with many people, privates, shops, and even trying to get people from the shops to do it after work, etc...they are all asking well over $100 just to do that one single homemade baffle which i know just takes a bit of time but its easy, so i'm not handing them my money.

i'm just going to keep it simple and put in the crappy 5's and live with it.

one last question: lets say you have 40 watts running to a component set, lets say a 4" and a tweeter with crossover... they are both 2 ohm...is it okay to switch out the 4" with a 4 ohm speaker but leave the tweeter there (which is 2 ohms)?

sorry about the previous confusing messages guys, i get a bit tired too and i get that "get off the computer" feeling so i type quick and leave. i hope this is clearer.

In my '99 stock speakers were.......

Dash 4 Ohm
Door 2 Ohm

In doors, I tried Infinity Kappa, Polk and I think MB Quart 5.25". To be honest w/ you, I don't specifically recall which was which but rather they were all underwhelming.

When I finally did it right w/ baffles, I used Infinity Kappa 6.75" (2 Ohm)

I appreciate where you are coming from on the time factor. I travel a ton and my Boxster, though I love it, is not a daily driver. It's stored Nov-April and LY I put less than 3K on the clock.

Anyhow, it will not take you much longer to make baffles than to swap out the existing speakers in the "tuned port" b/c in either instance, you not only have to pull the door skin, but also need to put on new connectors for the speakers. The baffles are mirror images of each other so they can be cut/made at the same time. You may easily be able to find a retired woodworker, etc. to make them for you.

Here are 2 guides to help you - a comprehensive DIY guide and a template for the baffles.
