Alright, here's the deal, I'm buying Airtrack's system, 2 12" W6's, Autotek 1000watt amp, running 500 watts x2 for the subs, and an autotek 4-channel amp running 75 watts per channel. Also he's including an EQ. He's keeping his MB quarts for his new car.

My question: Should I buy focal 4 inch coaxial speakers for the front and rear, or get 6.5" components in front and 4 inch coaxial speakers in back? If i change to 6.5 in the front, how do i do this? do i cut the door panel?

You will have to build a baffle to fit the 6.5's, but it is possible to put the 6.5's in the door no prob. I have them in mine. If you wanna go with coaxs in the back, which is a good idea BTW, you can do that too.

I'll try and dig up pics of mine and post them.

Well, I found out that focal makes a 4 inch component set, so im going to get that, along with focal 4 inch coax's in the rear. All is well

jmecbr900

Focal makes a great speaker, but I don't think a 4" component set will keep up with your subs in a properly built box. A 4" is very limited as to what it can do accurately. I would really urge you to reconsider getting the 6.5's instead. You will be very happy you did. The baffle will take all of 10 mins to build once you have the measurements. It's not that difficult and any reputable stereo shop should be able to do it for a small charge. IMO, it will sound much better than a 4" set. Really.

I'm not trying to rain on the parade. I just would hate for you to spend the kinda money you're gonna spend for the 4's and not be happy.

Just my .02.

Do I cut the baffle, or make a new one? And if so, how do i make a new one/what material? MDF?

jmecbr900

Yes, you're gonna make a new one out of MDF. You will just put the stockers in a box, whole, somewhere. The key is to center it correctly to avoid problems fitting the door panel back or getting in the way of the window coming down. It's not hard. Take into account the depth of the new mid. Mine is a little bigger than some, and it fit just fine.

alright, that seems easy enough to do. Probably will be a weekend project for my friend and I who are decently skilled. Where can I buy MDF? How much tme will this take?

jmecbr900

You can buy MDF at any hardware store like Home Depot. Depending on your skill and equipment, it should not take too long at all. You're welcomed to use the pic as a template. Notice that the reason why it's that shape is that you have to have some clearance around certain equipment/wires already there. Plus you have to factor how to screw it to the door. You'll see it when you get in there, but there are only certain places you can screw into to screw the baffle to the door.

Did you use the stock bolt locations to secure your new baffle? Did you have to drill into any metal?

jmecbr900

If I'm not mistaken, my installer used new locations, but I will ask him to be sure.

Thanks a bunch jmecbr900, you've given me the confidence to make the new baffles and put in 6.5's Focal components in the front and focal 6.5's coax's in the rear

jmecbr900

You're very welcome. I know you can do it but better yet you will be much more satisfied with the sound out of 6.5's than you ever will out of 4's.

I talked to my installer and I was correct. He did use new places where he screwed the baffle into. This is the reason for the shape of the baffle. It had to be cut that way to allow a place where to screw safely to.

Good luck and let me know how it turns out.

I agree with jmecbr - - - YEAH - NOT a good idea to go with only 4" speakers as your biggest midbass, especially all around. IF you only did them up front and still had some bigger 6 1/2 or larger in rear, plus your sub, then that can sound good (I did this in my Supra.) But going with 4" all around is a mistake, no question. Your transition between the mids and sub would be miserable. You need at least a 6 1/2 to make adequate low mids and not have to do this in your sub by raising the crossover frequency. If you were to try to overdrive the 4"s to get more low output, they would either sound lousy or you'd fry them.

Just a quick question: Will 6.5" coax's fit in the rear? I mean after i make a new baffle.

jmecbr900

yes.
