its not the LOC, the LOC just converts the signal from speak wire to Phono plug but that includes all frequencies, your amp needs to have a frequency cut switch usually says something like low/flat/high,
high cuts the bassy tones for example if you was running amped tweeters
flat keeps all frequencies if you were running say amped 6x9s
low cuts mids and highs for just running a sub
to be honest running your power and earth from the cigarette lighter socket isnt really advised as you will potentially be sucking so much power through the tiny 12v socket wires...
you should ideally be running you thick gauge cable from the battery to the amp.
