Hey guy's im in the market to looking into new doors speakers cause my hrs are getn up there now:D and plan on saving up to do this. and my alpine type s 6.5 2 way coaxials can't keep up with my system. so i was thinkn run these 8's in the door's what ya think? opinions comments on this would appericate it.

seems fine except the fact they are 8 ohm drivers and are hard to work into a car audio system.

seems that they are also a 6.5 and not an 8

true do u think it would be better to get the 6.5's?

If you want to build your own component set with 8" Mids, you could always look at the Kicker SSMB8's, they sound really good, and really pump out the midbass.

still the same issue with this one, see if they ahve it ina 4 ohm coil.

Please stop with the 4 ohm vs 8 ohm thing.

I'll post this link once again because I'm tired of typing the explanation.

However, here is a great driver for the money, and it does happen to be 4 ohm.

Those prices are in Canadian. Somebody on here knows the website in America you can get them from.

yea it doesnt matter at all if its 8 ohms or 4 ohms, just less power youll be sending it...

but anyways, i have the dayton 7" woofers... they look pretty **** beefy + **** as hell... i've yet to install them but from what i hear, they get pretty loud + low

Well obviously he is on a tight budget and I am assuming that he doesn't have gobs of money to power an 8 ohm driver seeing as you will need a pretty decent sized amp to get decent power to them.

My point is why install them and then underpower them?
might as well run them off your hu.......right?

and colt your right iam on a tight budget but my alpine type s 6.5s aren't just cutting it. so time for an upgrade so guy's help me out should i go with the dayton 6 1/2 run em off the hu or should i look into something else not lookn for comps just speakers 2 run off the hu.

well my assumptions were that he is looking at daytons a great driver but a very affordable driver and that leads me to think he is on a budget.


If I am wrong im sorry Ill just stay outta this thread then.

I think that those drivers are very good for their price.

You should buy whichever ones suit your desired application.

well first off your powering them off a headunit,

thats the problem, amp 'em up and you will most likely be satisified with them...

my kicker ks6's were fine for me until i blew one, only reason i decided to go d.i.y. comp's (plus it was a deal i couldent turn down)

which do you think would sound best colt here's my setup so far

a pioneer deh-4800mp hu , premier 6x9s revs in the rear deck , 2 12 inch pioneer DVC subs in a a enclosure tuned at 35hz with a sound storm 7band eq in the dash. idk if any of that matter's but thought might help.

those alpine's i got don't sound good amped up 2 me believe me i heard em. i don't like em .

Personally comps would be best off an amp, I understand that not in your means right now (been there done that)

I would think coaxials run off the hu would give you the better sound than a 6.5 woofer run off the hu.
Maybe a set of pioneer 6.5 revs coaxs?
Im not sure of what freqs you can get those to play but im sure its not as wide a range as a coax.......I could be wrong tho.

My understanding is that a woofer wont play above a certin frequency and seeing as you dont have tweets up front you would likely need the high end that a coax can provide.

maybe save for a bit longer and pick up a used 2 channel amp and a set of 6.5 or even 5.25 comps.

Just remember that your frontstage is very important in the whole scheme of things

Ok, what crossover would you use for the Dayton's... or for that matter ANY speaker you're looking at getting?

Are these replacing you typeS components? What tweeter will you use.

The TypeS components don't sound that bad... amp them.

Alright guy's i think im just gonna put $20 or $10 or $5 w/e i can do away and just keep saving up for a decent amp with a good pair of 6.5's and not rush like some people do on here thanks for all your help though guys:D. any other suggestions though just be sure to put up here im always open to listen to people's other suggestions and comments especially in car audio.

Please enlighten me why an 8 ohm driver is better than a 4 ohm driver in a car audio application?

I did. You obviously didn't read the link I posted. And I didn't say it was necessarily better. It definitely can be though.

To sum up, in order to decrease the impedance of a coil you need to reduce the length of the wire in the coil. From 8 ohms to 4 ohms you would have to decrease the length of the wire by half. This is also directly related to sensitivity. The shorter the wire, the less the impedance, and the less the sensitivity of the driver. Cut the length in half, you decrease sensitivity by 3 db. That equates to a half the output.

So, with a 3 db loss of sensitivity and double the power, you have the same output as half the power and a 3 db gain in sensitivity. So, there's really no difference between an 8 ohm and 4 ohm when it comes to output from the same amp. In fact 8 ohms can be beneficial, as no amp can actually double it's power with half the impedance. That's 100% efficiency. Just doesn't happen.

That's the short and quick of it.

To the OP, the Mach Audio MLI65s are quickly becoming the front runners in their price range. Zaph, of www.zaphaudio.com thinks very highly of them. The Dayton's were very good for the money, but they can't compete with the Mach.

if 8's wont fit in the doors, then you simply need to get a different car :)

also, not true.

MiniVanMan

not true.

also, not true.

I just want to get this clarified...

3 db gain IS NOT double the volume?

3 db loss IS NOT half the volume?


Also,

You know of amps that operate at 100% efficiency as the load drops by half?

I obviously need to be educated.

Depends on the application, both my Peerless mids and LPG tweets are 8ohm drivers, they seem to do very well on my Next VRz4.400 rated 4x82@4ohms. It depends on the amplifier as well. Take my Linear Power 2.2HV, being that it is a high voltage amp, when you increase impedance, say from 4 to 8 ohms, this increase causes a decrease in current, seeing that current and voltage are inversely proportional, voltage increases for the same power produced, basically the amp produces the same amount of power possibly more, and runs COOLER at the same time.

He also never said either was better, if you re-read what he said, you can obviously use both, I have been for nearly a year and couldn't be happier w/ my front stage.


not true.

also, not true.

If they're not true, why don't you actually post something to back it up instead of just discrediting him w/ no real information to help your cause. I'm not saying either is side is write or wrong, but at east he used something to help his side, you didn't.

8 ohm drivers are easier to work into a car audio system. Read some more before you respond differently.
