How much louder (8) 6.5" then (4) 6.5"

Properly aiming your speakers makes a huge difference. A lot of people fire their mids and highs at their feet, hips, etc. Pointing the speakers towards your ears can make a huge difference in volume and clarity. Try it with your home stereo, and you will see what I mean.

Having 2 sets of speakers fired directly at your head should be plenty loud. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif In my bus, I am running 1 set of 6.5" coax, and 1 set of 8" woofers and it is plenty loud. They are firing on axis, pointed towards my ears, mounted about stomach level in the doors. If you have your tweets mounted in the A-pillars (on-axis), they should be screaming when cranked up. Not overpowering the other speakers, but loud enough that you will want to turn it down.

Every 10db "sounds like" twice the volume level. 10db might not sound like much on paper, but IRL it is roughly double the perceived volume.

You want to focus on Proper sensitivity speakers instead of more component speakers. I've heard two vehicles in a past competition one with 10 component sets and one with 4 8" pro audio midbass and 2 supertweeters and it was a sh*t ton louder then the 10 components.

So where do I find 8" pro audio midbass and 2 supertweeters? have a brand to look at? I did think about adding some 8s instead of 6.5s to fill the middle.

If it is not going to be noticeably louder with (8) 6.5s. What about pair of 8" and 6.5" components in the back and a pair of 6.5" / 4"/ tweeter in the doors?, will it be fuller?

I mention 6.5 and 4 for the doors because there is a nice pre made pod for the factory opening and I can make it a sealed enclosure

Thanks again for all the patience with the audio idiot.

Thank you for that link. I had no idea 3db was that much difference to the ear,

You guys are a wealth of knowledge.

Like I said before. That is on paper, now add a ton of variables to it and it might be 1db gained. Like also said if you have not properly treated your doors that can gain AND sound better. Having tuning capability can also help.

I had a single 3 way up front and it blended with 150db. Unless you just want the wow factor, quality over quaintly always wins.

It would help a lot if you could hear a vehicle with a good 3-way front speaker setup that's thoughtfully designed and well tuned. I use a pair of 6.7" woofers with a sensitivity of ~93 dB, a pair of 4" mids, and a pair of 1" tweeters in my front doors. That isn't all I have for speakers, but this kind of setup is capable of getting far louder than anyone really needs to listen to for long periods of time. Match this with a good subwoofer and enclosure that plays a wide range of frequencies and you have a recipe for success that is not over the top.

Here's an example of an 8" 3-Way system I sell that is a ridiculously good value: CDT MX-383. CDT MX-363F is a bit closer to what I run.
