Sub wiring

I've got a single v/c 4 ohm Polk sub hooked up to a 4 ohm mono amp. Professionally installed. The installer ran two wires to each amp terminal & then attached them both to the respective speaker terminals. In other words, I've got two wires on the positive amp terminal going to the positive sub terminal and two wires on the negative amp terminal going to the negative sub terminal. Not sure why the installer did this, except that maybe he wanted to give me flexibility if I ever want to hook up a dual v/c sub.

Is the dual wiring on each terminal okay? Never seen this setup before, so I'm not sure. Also, not familiar enough w/electronics to know whether I'm affecting the amp's impediance or anything by running it this way.

    Its fine. Essentially, you're just using thicker wire.

    What kind of amp is it? The Kenwood amps had some servo feedback return, that you had to run antoher set of wires to. But it sounds to me like your installer wanted more money. Or he ran out of 12-14 awg cable and he ran two just to make sure. Who knows, but if you have a proper awg cable you don't need two. But it doesn't hurt either......

    That is what I was trying to say, in a nutshell.....

    They're pretty thin wires, so it would make sense that he was trying to "thicken" them by doubling up.

    Thx!
