03-15-2009, 11:28 PM
Right now im running these in my truck

The bass is pretty much not there in my music and I was wondering what all I would need to run 8s in my doors. Can I use the cadence x-over? I was looking at a pair of these

that mounting depth looks pretty deep, also think those are more based on vocals just recalling i heard at a shop and they are more of a loudspeaker type, go with a mid made for midbass

Are you looking to replace the current 6.5" driver, or add an 8" midbass to your setup?

If you are planning to replace the 6.5" driver and use the Cadence crossover, You will not want to use an 8ohm speaker (such as the Dayton have linked above) on a crossover designed for a 4ohm speaker (such as your Cadence crossover). It would also be helpful if you knew the crossover point and slope of the Cadence crossover, as you would need a driver that performs suitable up to that frequency and w/ the slope of crossover. Still not the greatest plan in the world, but if the crossover is a pretty basic crossover it should perform okay.

If you are wanting to add an 8" midbass to your current setup....then that is a whole 'nother can of worms.

Also, what does the rest of your system consist of? Where do you have the speakers highpassed? You said the speakers lacked "bass".....if you are talking about midbass, that's one thing. But if you're trying to get subbass out of a midbass driver, then right there is your problem and upgrading to an 8" isn't necessarily going to "fix" that issue.

thanks for the response squeak im really just trying to replace the 6.5s in the door now. I honestly have no clue what highpassed is so... and I want midrange(mid bass?) because I have another sub coming soon

The highpass crossover. Where do you have the highpass crossover for the speakers set?

Well I had it installed at a local audio shop sorry I dont hardly know anything about speakers but where can I look to see where it is crossed at?

It depends on your setup. There should be a highpass crossover set either in the headunit or on the amplifier. Try searching thru your headunits features and look at the controls on the amplifier (assuming you are running an amplifier).

That should be the first thing you check anyways. The shop could have set the highpass crossover too high which is what's giving you the issues.

o ok well i have an amp on them so Im going to check that out right now

yea that deffinately just helped I lowered the filter to around 60ish-80ish I think(doesnt show but 2 numbers) and it sounds much better. Another quick question is should i keep it on hpf or "full"

You don't want to run your mids full range. They weren't designed to handle low bass.

ok thanksfor the help

Look into running active, then you can literally choose any driver you want in your setup as long as you can make it fit.
