I am wondering if any one knows any company that sponsors people running car audio and doing competitions. I am currently running a sundown x12 rev 1 1250 rms d2 in a custom built box tuned to 32.5 Hz. Powering the sundown is a cadence ia9-hc 2000 Watt rms amp. Thats just the bass right now. Other upgrades are there just don't want to go on and on unless someone is interested.
