Wiring up your Focal ISS165

April 20, 2016 10:25 am | Uncategorized | 3 comments

We’ve had some feedback on wiring up the Focal ISS165 and tend to agree it is a little confusing. But we are a French company so we don’t want to make it too easy for you!

I assembled a set of ISS165 and took some photos as below.

You’ll see there is one wire in the tweeter circuit that is not used, it is labelled Display. Tape that one up. It’s used when we wire these speakers on demo boards, it makes the tweeters a bit louder for a showroom environment. For in-car use where there are lots of reflective surfaces nearby (windows, windscreen etc) it’s better to have the tweeters run a bit quieter. So just ignore that extra wire, tape over it.

The tweeter and woofer outputs which I have twisted together in the photos go off to the amplifier or the deck if you don’t have an amp.

  1. Hi Guys
    I have query about my ISN165 speakers, they only have iline crossover for woofer in box 2 wire in 2 wire out marked with sticker saying woofer, no crossover for tweeters, is the crossover built into the tweeter itself? went to install them in my ranger and came to stalemate!, help needed
    In the manual says theres a tweeter crossover with display wire too but mine didnt come with that or is there a new way to do it??

  2. Hi there,

    I have been having some trouble figuring out the wiring for this component set and was hoping I could get some help. I have the woofer wired to a harness for honda, but I left the tweeters for now because I am waiting on an order of speaker wire to come in.

    I’m confused as to which wires I should twist together (as they have no indication of polarity on the tweeter wires); the display wire is taped over, but that leaves me guessing between the “car” wire and the unlabeled wire to twist into the woofer. Can you provide some clarity as to which wire should attach to where, or if it doesn’t matter?
