I know very little about fi audio, pretty much been a JL user. I want to switch to fi because I want to support a local company. I have about 800-1k budget for sub and amp for this build. I want a single woofer and don't care if its a 10 or 12. The sub will be mounted in acustom sealed fiberglass box. I listen to rock mostly. I like my bass to be punchy. I dont want the bass to drown out my comps. As for my set up I have rainbow germs. And a 2 chan sundown amp. Its all going in my evo x.
