radio harness install question/problem
srry that its a little long, the more detail the easier it is to understand haha
so i installed my head unit a few weeks ago, a pioneer avic-u310bt and it went very easy except for one thing, when i turn on the car the stock 8inch door subs pop loudly, the sound made if you cross wires. now i looked over the specs the harness itself and it was all matched fine and done right, when i installed it i noticed that there was 2 plugs to splice in the regular harness and the stock amp harness( it contains 2 RCA males and 2 12v positive amp turn on wires, both the same blue with white strip) and i had a problem on were to put those 2 identical wires. i tried the red amp turn on wire and the yellow wire and even spliced it into a door speaker positive wire. when i did all these swaps the popping got softer then louder and switched back and forth and i got it to be very soft but when i turned it up the stock subs just die out due to not enough power from the speaker wire. ive gotten so tired of it i finally asked my friend who works at a best but install bay and he told me to splice it into the pioneer harness's remote control wire(also blue with white stripe) and that would fix it, the subs dont die out anymore but now the pop is louder then ever. anyone have any ideas one what i did wrong, or what to do for any of you who installed there head units.

You wire a 5 v voltage regulator, not a resistor...
RadioShack
LM7805 5V 1A Voltage Regulator in a TO-220 package
One terminal to 12V, one to ground and the third
5v output goes to the amps turn on lead.
Problem solved...
