After reading in here about how much better 6.5's would sound in the doors (and how they were even better than 6x9's because they were round) I finally built the template, ordered some speakers and installed the first one today.

Wow... am I diappointed. The new speaker doesn't sound any better than the Pioneer (in the stock door size) I am replacing.

I had put the Pioneers in a few years ago, and was disppointed with them, because with the small size you can only improve to certain point. But since they were the stock size and I wouldnt have cut, or build anything I thought Id give them a try. Yes, they were better, but not what I had hoped.

Fast forward to today... I expected a big improvement but saw None. In a blind taste (sound) test, switching balance control between left and right, there was no diff between new speaker on drivers side and old speaker on passengers side.

What gives? Shouldn't I at least had some more bass from the larger speaker, if nothing else??

The new speaker doesn't sound bad, its just not any better. The rear speakers still over power the front, and you must compensate with the faders.
Thanks

What kind of speakers did you buy, just whatever was on sale or something that is supposed to be decent? I always heard that the 6.5" are better for mids and highs, so maybe you are just not sending the right signals? I still plan on doing 6.5", but I'm going from the stock speakers, so I better hear an improvement.

2 suggestions...

- Make sure the polarities on the speaker are the same and not reversed. (If you are not sure, switch the leads on one of the speakers and see if the bass improves.)

- Add some type of sound deadener (Dynamat, Grace Ice-Water Shield, etc.) to the door to help "seal" it up.

Did you buy 6.5 speakers or a set of 6.5 components.... If you purchased a decent set of 6.5 components you should notice a decent difference

Here is the link to what I got.

They seem to have good Freq Response, and other people gave them OK/GOOD reviews.

I did try switching the polarity of the wires. I DID notice a difference by doing that, but they way I had them the first time, was the better option.

I'm not getting any bad virbration from the door. Does the sound deadner really help it sound better, or is that just to quiet things down from road noise, and vibrations?

ehhhh dont know if kenwood was the best choice for your speakers. plus there not componets so the frequencies wont be as good. with components you have the choice of what frequency you want your mids highs and lows to be. they are a little more costly but u will prob notice the difference. i had stock speakers but my friend threw in stock caddy speakers when he sold his sub to me. i replaced my stocks with the caddy stock speakers and they are amazing! very clear sound and no distortion like the caprice stocks.

I recently changed the stock speakers to alpine components. Just before I did the swap I had the stock speakers running off a 80 per channel (RMS) amp and they sounded good.

When I did the swap to the alpines I was a little dissapointed, they sounded the same if not worse than the stock speaker at first. I noticed they were not as efficient as the stockers. But then I got to playing with the cross over points and gains and go them dialed in. The way I have it setup now sounds incredible for the music I listen to at almost any volume.

But getting back to the OP's problem, I also thought that the new 6.5 had no bass when I first put them in. I think it was just that they were less efficient than the stock speakers so you need more power. Does any know the impedance of the stock speakers?

"I did the swap I had the stock speakers running off a 80 per channel (RMS) amp and they sounded good."

There is no way that you had over 80 rms running to each stock speaker, that is absurd. Also, what kind of alpine components did you buy? Type E? The type e and s only handle 50rms and the Type R handles 70 watts rms...... Your amp depending on the quality(a real 80rms x4 channel amp is pretty expensive) is overpowering the speakers by a lot. Anyways, all i wanted to say is that i cannot believe you had 80watts rms running to each stock speaker. Impossible.

Back to the original post. I am not sure if this is an option but i would return those speakers if possible and buy a halfway decent set of components for the same price

Not the best set of components, but not too bad either you will definately hear a difference. If you are really looking for good clear loud sound you should definately look into getting a nice 4 channel amp and upgrading your front speakers to some nice components, forget about the rears throw a pair of 6x9s in and be done. JUst a thought.

i installed a set of 6.5 inch cadence components ($79.99 and 5.00 to ship, check ebay) and i have to say that i am truly glad i made the switch. they are being powered by a hifonics zeus zx6400 that is rated at 85 watts/channel at 4 ohms. i used the template that was posted in this forum a while back. the only thing i did not do was drill the hole for the tweeters. i chose to mount the tweeters in the a/c vent. sounds good to me if i must say so. if you dont have an amplifier connected to your 6.5's, then that may be the cause of your dissapointment jmho.

Deadening the door panels will help greatly, as will an external amp, and better speakers...

Usually if you can't get enough lowend out of your door speakers you need to look into proper deadening and sealing of the panels, a la the sticky at the top of this section, or you could have phase issues.
