I have been having a problem with the system in my car. I have a 1000 watt Sundown amp and 2 12" 500 watt subwoofers. I kept my factory head unit. Every time I turn off my car, my amp continues to power my subs for about 30 seconds then shuts off. It is very loud and annoying. I called the business that installed my system and they said there was an impedance fight between my factory radio and amplifier. Does this mean I need to buy a new head unit? If so, how do I match the outputs of the radio to my amp so that this problem won't continue to happen?
The answer they gave makes no sense. However, you would have better control of your sound with a nice Pioneer headunit. Does the headunit and subwoofer power up at the same time when you start the car ?
Yes they power up at the same time. It's after I turn off my ignition that the amp continue to run a bass-like noise through my subs and it only stops after I open my trunk. A Pioneer head unit would stop this? I just don't want to drop $200 on a new radio and have this same issue. I don't exactly know what the problem is.
Better figure out the problem before buying anything else, yes.
Because my name is on the business, I work hard to make sure you get the best possible shopping experience. I look forward to hearing your comments .
