i got the wiring right. the box is sub up port back in a chevelle. i had 2 12poineer 305's in 4ft that was alot louder in the same car. i dont get it

is the box to small? tuned to low?

what is going on with this setup? like do you think they are reaching decent exscursion capabilities? otherwise maybe you arent presenting your amp with the desired ohm load and lacking power. are you getting port noise? i still think you need more port area

no port noise. i know i need more power but even when i put it in my friends car on his amp it still wasn't right. i'm getting decent excursion. moving alot of air too. does a 8 inch port take up that much space? more port area? I'm thinking about trying 6ft. 2 6inch areo's maybe?

well an 8 inch tube is 50 sq inches of port giving you about 10 sq in per cube. i ususlly use 12 to 14 per cube but really you shouldnt lose trwmendous output with what you have. pics of box/setup?

 

[jusBloud 10+ year member]

i can get pics tomorrow.

do so we can see what you got going on

 

[jusBloud 10+ year member]

the box is 32 wide 16 tall and 22 or 23 deep. 8 inch port almost 16 inches long

 

[phemps 10+ year member]

let me check to see if your tuning is accurate quick

the box is 5.1 before displacement. how much room does that port take up? that may be the problem
