    I recently hooked up a woofer to my car with a 300watt amp. works great except it becomes less powerful when i have the car turned on compared to when i just have the ignition turned on.. battery problem perhaps?

    any ideas appreciated :)

    Strange on, it would normally be the other way around!
    Double check your ground locations and make sure they are on good clean bare metal. Also your rca cable's arent on the same side as your power cable are they?

    what car is it ?

    is the amp 400w rms or 400w max (if you dont know, the make and model of amp would be helpful)

    From what point in the car did you connect the 12 volt positive supply. This ideally should be taken off the battery and suitably fused.

    thats the amp in the link..

    yes rca's and power cable are on the opposite sides..

    Powered from the batter with built in fuse in the wire
