Recently bought a Toyota Aurion, which cames standard with 6x9s all round. The factory 6x9s though are cheap crap as you'd expect, but overall the system isn't too bad considering it's standard.

Anyhow did some fitting and found that my 8" drivers from my previous car would fit, so I made some new pods etc and fitted them into the 6x9 spot in the front doors, perfect fit.

HOWEVER the bass from the 8's is virtually non-existant compared to the factory 6x9s - they sound barely audible. I checked wiring etc and yep they certainly are moving on the bass hits, just nothing coming through.

I remember in my last setup running off an amp they really thumped - is the fact that I'm just running them off the standard cdplayer the reason for this poor performance? ie they're not an sensitive as the factory speakers?

Also a 6x9 speaker, just going off size along, is roughly the same as an 8" right? Ie they'd have close to equal bass potential all other things being equal?

and FINALLY, the standard setup inthe front of the car is 6x9s in the doors, dash mount tweeters. The factory 6x9s are single cone, no midrange etc. So would it be fair to assume that by switching to my 8" drivers eventually, midrange performance would be about the same? I know 8's arent reknowned for playing fairly high and can disappoint in a 2-way setup for midrange performance, but what makes the factory 6x9s any better?

As you stated, you were running them off an amp and the sensitivity of the speakers is the difference.What configuration were you running the 8s in(sub or mid in a 2way/3way setup).Check the freq range of the 8s and that would explain why you're not getting the same response as you were in the previous car.Running off the factory h/unit won't supply the right amount of power the 8s.

Are they in phase? Fade to the front, then shift balance form left to right. If the bass is louder when on one side, then one channel is out of phase.

Toyota probably spent $$$$$$ on making them work in that vehicle..........

[vtviper]

nah definitely in phase, but I did the fade fully to each side also to make sure, the difference really was that obvious.

Factory setup doesn't run any crossover on the mids, just a cap on the tweeter. Looks like I'll just need to wait till I get my amps going.

But Id still like to know why a single cone 6x9 speaker is "supposedly" able to produce midrange better than my 8" does, aren't they essentially the same cone area at the end of the day?

[RoVer™]

It's not necessarily the cone area factor, more like what it was intended for. a 6" mid will struggle to produce sub bass but won't have problems with midbass and midrange, where-as a 6" sub will be vice versa.

[Joe Bellissimo]

Could be a stupid question, but are they sealed as well as the 6x9s were?

[vtviper]

yep they were properly sealed

Sounds like a lack of power if all things are equal, which was your initial idea.

Amp them up and see how it goes. If your in NSW I could go run my MaxxBass103 on it and see how much potential they really have. Never heard one connected to 8" woofers...

[Cyberpunky]

see Northfield Pauls original reply. the reason is the sensitivity of the 2 speakers. The factory 6x9s are very sensitive and are loud with 3-5 watts but unfotunatly distort if given much more power. The 8s are obviously less sensitive so quieter with 3-5 watts but able to play a lot louder without distortion if fed more power(amped)

what is maxxbass103?

[Cyberpunky]

its a processor that using some cool electronic trickery makes your normal full range speakers sound like they produce sub bass. They work pretty well if you cant fit a sub, like a little coupe etc. not as good as a real sub obviously but pretty impressive none the less. You really need to hear it to make up your own mind.

If anyone in NSW wants to have a play with it just check my profile and add me on MSN.

Its sitting in my living room until it sells so I might as well have a little fun with it.

Vtviper you in NSW?

Is it just me, or is everyone simply skimming over the fact that maybe the 6x9's are optimised for IB, and the 8" isnt? Given the 8" is not firing into any box, may be the biggest reason why you have no low end.

was inches from the reply button to say just that when i saw your response

[vtviper]

The 8" is actually a limited release from seas lotus specially designed for car doors - In previous setups I had it really hammered but yeah they were amped then.

Joe - Sorry mate I'm in QLD, I didn't accept you on MSN cause it sorta looks like an advertiser's email, I've had to block a few of those recently.
