So I have had my Evil 15 for about 2 months give or take and love it! I am powering it with a Sundown SCV3000D in a 4.25cuft enclosure tuned to 32hz. I am thinking of increasing my power with an SCV4000D. Will I notice the difference with the increase in power and is it worth it? I also know that I will need to rebuild and go with something on the smaller side but how big should my box be with the increase in power? Any and all help is appreciated!
