Left, Right, Left in the dash

[Blue85]

Anybody ever try running both 3.5" dash speakers as one channel and the center 4x10 as the other? Perhaps both driver and passenger can get stereo imaging out of it. Just not sure how it would mesh with the rear speakers.

I had the R dash speaker break while I was traveling (terminal broke off). Looking at it I remembered the 4x10 I had put in the center of the dash several years prior (it had a passive crossover to run just "lows"). So I ran the right channel to that speaker and from my seat it sounded better than the R speaker. Getting ready to take the dash off to make some changes and thinking of trying it. But what about the A-pillar tweeters? Install a 3rd tweeter in the center?

The center is the best place for a speaker.

Equal distance from both driver and passenger. I might try to do the normal 3.5s in the corners and 2 4" in the middle

So I tried this concept out using parts on hand and it's not bad. I put Right to the center 4x10 and Left the the far right dash speaker, which is now a 5 1/4. It has a mesh top and foam seal, so it seals to the dash like a factory speaker (obviously OEM from some car). Left is also run to the crap 4" above the cluster, but through a resistor of about 15 Ohms. This leveled the L speaker out and allowed removal of the caps (HP filter) I had on it before. So the load on Left isn't much below 4 Ohms (maybe 3.3, but with speakers this small it's not a big deal). Really, the 4" speakers were like screaming mid/tweets and I was always EQing the dickens out of the system to compensate.

I wish I had good 3.5s to compare this to, but my old ones are trashed (Probably how the "full range" 4's ended up in there to begin with). Really, I remember my system sounding good back in the day with just 3.5s up there. It's really just for presence and imaging. You totally depend on the rear speakers for the mid-bass.

It would be cool to have 3 good speakers up front and a center channel processor.

A processor is the best way to do it but you can do a poor mans version by pulling the pos from one side and neg from the other side along w/ an l-pad to dampen it down... If you wanted to try something as an experiment..
