    Hello, 2007 F430 spider. The driver door speaker and tweeter both started to not work intermittently. I noticed they would work again when taking right hand turns then go out again when the car straightened out of the turn. Now they do not work at all. I took the door apart hoping for a loose connector but all seems good. I disconnected the passenger door tweet and the driver tweet does work in the passenger connector so the speakers are working just not getting the signal.
    I'm not sure what to check next. Any suggestions?
    Thanks,
    Dave

    Does your car have the factory hi-fi option? That is, does the car have the little speaker box behind the seats and the small booster hanging under the center of the dash?

    Mine does the same thing with the Bose setup. Is this an amp problem, Mike?

    Most likely. I receive many, many calls of this nature. Entire channels go out, transistors/capacitors blow, resulting in crackling and popping noises, etc. You can get the factory booster rebuilt, but in the end you still have a 60 Watt booster with an incredible (from Ferrari's own documentation) 10 percent distortion. The audible threshold for distortion is 1 percent. And a new one is over $1600.00.
    Here is a 420 Watt, 0.3 percent (inaudible) distortion, plug and play alternative solution: https://scuderiaaudio.com/product/360-430-super-amplifier/
