just installed a pioneer headunit into my 2000 mustang gt and i have the mach 460. everything sounds great, my only concern is when i turn my car on and my headunit gets power u hear a slight popping in the speakers, pops once thats it, doesnt do it when i turn the car off. any ideas? when i used to have a sub it kind of did the same thing.

 

it dont pop when the engine is off?

 

pops if i just have it on accessory or when engine is on, and only when i take it out of standbye mode and select cd or tuner which then its sending a signal to the speakers.

 

My old deck used to do that...I dought you can get it 2 go away..

 

yea i doubt its anything serious, but i wish i knew what its from. going to ask my buddy later who used to work car audio at bestbuy what he thinks it may be. (lol and i work at circuit city)

 

well its something to do with your factory amps it shouldnt hurt nothing its normal when you add a aftermarket to a factory amplified system

 

as much as i like the mach 460 sound system i think i might get a whole new setup for the speakers in the future. its cheap for me with employee discounts and i dont have to worry about gettting a million n one adaptors to get things to work

 

According to other posts I've read here, that's from sending a 12v turn on signal to the factory amps when they're expecting 5v. The solution is to put in a 5v voltage regulator which I happen to be soldering up right now. If the weather doesn't suck again this weekend, I hope to have this thing installed Saturday and will have some photos. As far as I know, it doesn't hurt anything except for the annoying sound. The voltage regulator plus a small circuit board to mount it was about $3 at Radio Shack.

 

hmmmm never thought of that, yea please post some pics im interested

 

if i was you i would just scrap the 460 system and replace with aftermarket you will have alot better SQ
