[QUOTE="Jeffdachef, post: 8630442, member: 650438"] big 3 upgrade along with maybe a dedicated ground run, run wire through that point you drilled and run underneath the car, add a grommet. Yes it can cause voltage drop depending on the rise at certain frequencies where you arent satisfied with the output and try to bump it up to compensate when in actuality you are clipping it. Some poorly made boxes have massive voltage drops below box tuning and some tuned really low can easily be pushed into clipping when playing a much higher note from what i've seen. You wont know specifically unless you do lots of clamp tests. Just For his information, we dont really go by the port per foot rule, its just a general guideline for noobies to get a feel for what might be needed. On a sub modeling program like winisd, your rear air velocity values are through the roof. I'm surprised you dont have port noise to be honest. Could very well be at the point where its just a leaky sealed box where air cant even escape properly. [/QUOTE]
