[QUOTE="lotas, post: 926407, member: 557735"] the wire is very small. When you add more accessories, you need to add something like a relay. A relay will allow you to control many acc. (two amps, maybe your EQ or whatever) with a small amount of current (the HU turn on or the power wire) just go buy a Bosch 30amp relay from radioshack or [URL="http://www.partsexpress.com"]http://www.partsexpress.com[/URL] or [URL="http://www.cardomain.com"]http://www.cardomain.com[/URL] they are cheap, they are extremeley easy to wire and work with, you could even put in a switch that will control your EQ. My cooling fans are wired to a relay, which is wired to the HU...with a switch. Therefore in order for my relay to have power, the HU has to be on, if my HU is not on, relay does not have power, and switch doesnt work. Once HU is on I can control the fans with my switch.
