I im pulling the two 8s out of mr car and puting two 10" compvr's should i port them or not? is it harder to get a good sound, the port would be 4" in di. and only 6-8" deep.

6" - 8" is not going to cut it. You could use an elbow to extend the length if you decided to go that route, though.

My advice... study up, or stay sealed. Ported is pretty easy to mess up.

is there any reason you chose 6-8" vent length?

you can't just pick some random length.

its not random, i think it would be all i can fit. i am trying to fit the sub box and a

N20 bottle in there. that is why i asked if it would work. what should be the ci. and how long should the port be?

Enclosure size, port area and port length depend on many variables. The T/S parameters of the sub/subs chosen and the type of response you are looking for, to name a few.

well i have two 10" compvrs and the enclosure will be around 1.25 cu. each I have two ports that are 4" in di.

The MINIMUM recommended ported enclosure size for a them subs is 1.25cft net. Since you have 1.25cft. gross, I'd suggest leaving them sealed or building an entirely new enclosure. They want more like 1.75 cft. after sub and port displacement.

I haven't buit the new box yet I may bs able to squeez a bit more out of it. if i cant fit the nos bottle in back than i will just remove my back seats and put the nos there.

Are you really willing to dedicate 4 cubes to these subs? If so, port 'em.

 

[99greengt 10+ year member]

well i dont have a trunk as it is now and i dont want my back seats so sure.

Start with a 4cft. enclosure, add a divider in the center and a 4" port in each one(13"-19") Longer for SQ, shorter for SPL.

 

[99greengt 10+ year member]

whats sq and spl?

 

[BEAVER.989 10+ year member]

sound quality - sound pressure levels

I'd start longer, trim a little at a time until I got the sound I was looking for.
