How hard is it to install an amp and a sub?

How to install amp/sub in my 2001 Lexus IS300?

• I just got a sub and amp from my buddy and want to install it myself because low on funds. I went and bought a kit with everything I need for $40 and also got a hi/low 2 channel converter because I'm using my factory head unit. The only reason I'm going to do it myself is because my battery was recently relocated to my truck. I don't have to run wires through wire wall or anything and hardly need any wires bcause the sub, amp and batt are in trunck and the 2 ch converter will be also in the back rear speakers. WHAT I NEED TO KNOW: I need to know how to run the remote terminal from the aftermarket amp to power. I heard I can possibly run it to the cig light? well I have one in the center console which is very close will that work? most forums are for of course people who have there batt were its suppose to be and I'm lucky with it being in the truck and will help with labor. can anyone help me? sorry i wanted to get all of it out. Thanks

• Answer:

  The remote turn on wire should be tapped into something that runs as an accessory. Typically that holds true with the cigarette lighter. If the cigarette lighter works when the vehicle is off, then you know it is a constant source, and will not work. If it works when the key is turned to accessory, and when the vehicle is on then you know it's an accessory. Other options for an accessory wire will be behind the radio typically, and also at the ignition harness.
