So we were at our friend's house helping them clear out their garage, and we found these. We don't know what they are, but our friend said we could have them... The one with the clear plastic says Memphis on it, and it says IN and OUT on it, the out is on the end with the yellow capacitor. There's one thick red wire and one thick black wire running into the IN end, and 2 small red wires and 2 small black wires running out of the OUT end. The one without the plastic face on it has a tag on the left red OUT wire that says LF (Left Front I'm guessing), so I'm sure they're for car audio.The yellow capacitor says "3.3J 100v MET" on it. Any guesses?
And by the way, I'm not exactly new, I just registered and forgot my password for like a month Thanks guys!
