Grommets? How to pass wires thru wood

hey guys, I am trying to put a good finish on my amp rack.  Now I have holes just drilled on the wood and have the wires running right thru them, the wood is about 1/4 inch thick.  I think it's ugly, what do ya'll use for a finished look?  I found some rubber grommets but they are for sheet metal, not 1/4 inch thick.  Is there some kind of plastic cylinder  with a lip on top or something if you know what I mean.  I can replace the wood peace to start with a fresh one without hole if there is some other way?  here is a sort of diagram of my amp from the side.

Hmm. I've always found MDF to be startlingly easy to manipulate.... I just straight drill holes with an appropriate bit, then sand/dremel out the top of the hole, as you would round off a PVC port ...making it all even and everything.. pull the wire through... I mean... it doesn't look like.. factory fresh but I thinks my racks look nice. On the other hand, your grommet idea is great. Try Lowes for grommets that might fit. I know the two Lowes near my house have a massive selection of specialty pieces like that. A third idea: Put a piece of wood ... maybe 1/4 - 1/2 inch thick under your amps(but smaller than the amps, so the wood block just makes the amp stick up) then mount the amp with big screws to the amp rack under the block of wood. Then you can run your wires *under* your amps and hide them off that way. The amps sticking up can look kinda cool, depending on the rest of the install. I've seen a couple of cars done this way... I think lotsa install shops model their amplifiers like this as well. Anywho, good luck to ya! Let us know what you end up doing eh?"I'm finished!" - Daniel Plainview

When doing an amp rack I find it is much cleaner to raise the amp 1/2" and drill under the amp and run the wires up from under the amp.Certified Security Specialist

Always check info with a digital multimeter.
