Check the 20amp under the hood.

I blew quite a few of those... I also had my radio ground wire go bad, so I had to jump it down at the cig.

I forget, if your standing alone the driver side fender, looking into the fuse box, it is the upper left orange 20 amp fuse.

Your suppose to remove the negative battery cable before doing any radio wiring or any electrical wiring for that matter...

Turn the volume down on what ever input device your plugging in, more then likely your overloading it.

My guess is that you used the power antenna lead as the amp turn on. Many radios turn off the power antenna lead when you switch to any other input source. You will need to verify that and find a different turn on lead source.

This...

Unless your car doesn't have a power antenna.

Does it power OFF or go into power protect? Remember, you need to run the amp to the 12v hot on the aftermarket harness, most often the BLUE wire.

i used the blue wire which im pretty sure is the amp, on the aftermarket sony wiring,
and there is also a blue wire with white stripe on it which i think is antenna

Rip The E Brake · 12-16-2009, 04:36 AM

Blue wire with white strip is probably it., but IDK.

I didn't mention anything of the car as it doesn't matter. You need to brush up on skills and experience. Not sure which model he has but here is a Sony http://www.docs.sony.com/release/CDX...stall_conn.pdf. You need to use the blue with white stripe which is the AMP remote lead.

The plain blue supplies power to the antenna lead ONLY when the radio is in in tuner mode as stated in the instructions. Does not matter what vehicle it's in or if it has a power antenna. Also MANY new cars including Toyota and Scion do not have a power antenna BUT they do have an antenna booster amp that needs power or your reception is garbage.
