Hi all,
Umm I have a visonik 10 inch sub with a visonik 300 watt amp and would like to up grade should I buy new amp or sub or box??

Not sure plzzz help:confused:

What are you trying to get?

You're also going to have to upgrade the power wire for the amp depending on how powerful an amp you get. For anything over 500watts rms, you'll have to upgrade to 4ga wiring for the power wire of the amp. The 4ga wiring will also include a bigger fuse
