nooo. thats the opposite. typically, you put a sub in a larger enclosure for lower power, and smaller for higher power. but it depends on the sub, power, vehicle. you'll learn quickly on this site that car audio is a biiig game of variables. the best tool you can have is experience. just start off simple, nothing too crazy. use peoples advice, and you will gain knowledge and experience. another thing i'll tell you now, is that the enclosure is the most important thing. make sure you get a good design for one, or run your design by people who are good with them to make sure its good. there are plenty of people on here that are willing to help and offer advice, so just ask.
Thank you mate.... I will start off simple.... All I want is 4 skar vvx on the 4500 but it may be easier to just save more and pray to god that dc will ship to aus and go for 4 level 4s insted
