So I am new to club lexus and this is my first post. I came here looking for help. I have a 2004 ES330 with the standard lexus sound system and no navigation. I have decided to put in an after market head unit with two 12 inch subs and amps. I have the metro Wiring Harness hooked up with my head unit and It works perfectly. I have the amp hooked up, rca cables in the back of the head unit connected and the amp turns on but the subs wont turn on. Im guessing it has to do with the stock amp and sub that comes with the car. If anyone could tell me what to do to override the stock amp and sub to get that aftermarket ones working it would really help.
Thanks

What H/U do you have? You might need to use a function in the h/u to turn on the sub outputs, and also set your gains.
