    What's the best way to cut plastic? Which tools are best? Hacksaw? Jigsaw? I'm sure a utility knife won't do it. I want to cut part of my door panel and make the hole slightly larger. I guess circles are difficult to cut. I don't have room for a kick panel or the money so the speaker's going in the door.

    Lots of ways to do it. Dremel, which suxs, Hot knife platic cutter, Die grinder which is my favorite but can be damaging to an unexperienced user, For someone who has not done this before, i suggest a jig saw, with a medium or fine toothed blade, run at medium speed and fed slowly. To protect the panel and make cut lines easier to see, get some wide masking tape, stick it on the panel around the whole area where you want to cut. Then pencil on your cut line, and go to town. Take your time, dont get in a hurry, even a jig saw can screw up a door panel..............

    Can I make a suggestion? I am going to assume that you really like your door panel.

    Cut out the hole you want in MDF first. (do not experiment on the door panel). Work it, sand it, till its perfect. If you screw up no problem. (its not the door panel) Cut another one. MDF

    There is method to my madness

    Once you are completely satisfied with the MDF hole we can now transfer it to the door panel. Place the MDF on the panel and mark the location of the hole. Stay INSIDE the mark and cut using any method you like.

    Once you have a hole Put the MDF Template back on and lock it into place using C Clamps. Finish the hole using a Dremel and a sanding wheel. The MDF template will keep you in the lines.

    Your hole will only be as perfect as the template you make. You can screw up on as many templates as you like. You do NOT want to screw up on your door panel even once.

    Told you I was mad, or was it my method. Whatever

    Bill,

    That is actually a pretty much perfect hard to screw up method...but yes there is madness in it...not for the impatient.

    Impatience will result in a screwed up door panel.

    Thanks very much for the suggestions. What is an MDF? I'm new to this.
    I'm not going to pay more for a kick panel than a speaker.

    Medium Density Fiberboard...Same stuff everyone uses for sub enclosures.

    I just thought of something...is MDF the same stuff they use as subflooring in houses?

    Medium Density Fiberboard.

    Now, if the holes don't have to be perfect (i.e will be covered by something else) any method will work. But it has been my personnal experience that any job worth doing is worth doing right. Most problems people experience is because they got in a hurry and didn't think it out.

    Take your time, be patient. Yes I'm really old and its nearly my bed time.
