Bass speaker start up noise
Hello anne845,
It sounds like the installer wired the amp remote turn-on terminal to an "accessory" lead in your vehicle. Many stock radios do not have a dedicated amp turn-or lead and the alternative is to connect the amp to a switched power source (ignition or accessory). This means the amp turns on whenever you turn on the vehicle ignition, often resulting in a thumping from the subs. It is a perfectly satisfactory alternative, and will not damage either the amp or the sub. But it's irritating.
If the thumping is objectionable, have your installer wire a SPST (Single Pole, Single Throw) toggle switch inline with the turn-on wire. The switch should be mounted so it is accessible by the driver, and whenever you turn on the radio, turn on the toggle switch.
Hope this helps.
