SPEAKER PHASING
To be sure to have the correct speaker polarity (phase) you
can check this by using a 1,5 Volt battery .
Connect a cable from the battery plus-pole to the speaker
plus, and a cable from the battery minus to the speaker minus.
If the speakers are correctly connected the speaker cone
should move outwards on both right and left channel.
This check must be made on the cables going from the
speakers, to the output terminals of your car stereo or
amplifier.
