  1. Engine noise is caused by 2 main problems.

    1) The grounding of your amps is average or;

    2) Your amp power cables and RCA (amp input) cables are running next to one another.

    As stated the grounding points in the corolla aren't all that flash hot. However i found that placing the earthing cables under the front chair rail bolt worked very well for the door speaker amp and under the child restraint mounting bolt in the rear for the sub.

    Separating the RCA input cables form the power cable also works a treat. The high current being drawn through the power cable creates a magnetic field which in turn makes the high pitch whining (which often changes in tone with rpm as the alternator creates more charge). Separating the two by any distance will help. Around 10-15 cm is preferable.

    If none of this works you can purchase car audio noise filter. These cost around $30 form jaycar and will fix your problem. An car stereo line isolation transformer is also another good option that if used with the nose filter will guarantee a noise free car stereo setup! (all up these two items will cost about $50)

    Hope this has been of help :D

  2. Hey Guys

    Ever since I have installed my stereo (amps etc) my +ve battery connection has been oxidizing quite badly. My current one will have to be replaced soon and im just wondering is this is a regular problem and whether or not it can be stopped.

    I have tried an anti-corrosion product after cleaning the connection properly with boiling water etc but the problem still persists!

    Any takers???

    Cheers

    Vaseline is your friend :yahoo:

    In more ways than one :P

    Cheers
