Running New Speaker Wire Into the Doors Without Drilling (1G Acura CL)
Introduction
Upgrading the door speakers usually means finding a clean path for the new wiring, and many people assume the door must be drilled or that the wire has to be fished the full length of the flexible rubber boot with a coat hanger. Neither is required. This guide routes new speaker wire from the cabin into each door using the existing factory pass-through and a small, taped-over slit in the door boot, leaving the weather seal essentially intact and the result hidden. It applies to the first-generation Acura CL and to similar Honda/Acura doors that use the same connector clip and concertina boot between the body and the door edge. Follow the same sequence on both sides; the driver side is straightforward, while the passenger side is more cramped and benefits from removing a trim piece for access.

Reference
Tools Required
- Phillips screwdriver
- Flashlight
- Hobby knife or razor (X-Acto)
- Trim/panel removal tool
- Electrical tape
Parts Required
-
Speaker wire (14 gauge is ample; 12 gauge also passes through)
-
Braided wire sleeve/loom (optional, for a factory appearance)
Safety Warnings
- ⚠ Cut the rubber boot away from yourself and keep the slits as small as possible to preserve its weather sealing.
- ⚠ Avoid nicking the insulation of the speaker wire or the existing factory harness while cutting and fishing.
Step-by-Step Instructions
1 Remove the speaker and its baffle
With the door panel already off, take out the four Phillips screws that secure the plastic speaker baffle, lift the baffle away, and unplug the factory leads from the speaker. Removing the speaker opens up the door cavity and gives you a clear line of sight and enough room to work through the speaker opening.
2 Locate the door connector clip through the speaker opening
Crouch down and shine a flashlight up through the empty speaker hole. Find the rear of the plastic connector clip that mates with the rubber boot on the outer edge of the door. Look at its top corner: there is a vacant, unused cavity in the clip. That opening is big enough to pass wire straight through to the outside of the door.
3 Feed the new wire through the vacant clip opening
Push the new speaker wire through that empty slot in the connector clip until it emerges at the door edge. A 14 gauge wire slides through comfortably, and installers in the follow-up report that 12 gauge also fits with some effort. If you prefer to keep the two conductors separated, use the pair of available openings, sending the positive lead through one and the negative through the other.
4 Free both ends of the rubber boot
Move to the flexible concertina boot that carries the factory wiring between the body and the door. Detach it from the door end and from the body end so that it hangs loose and open on both sides. This gives you access to route the new wire alongside the existing harness.
5 Slit the boot and pass the wire through it
Using a hobby knife, carefully cut a small slit near the door end of the boot, just wide enough to admit the wire. Feed the wire in through that cut, then make a matching cut at the cabin end and bring the wire back out. Passing the wire in one slit and out the other is far quicker than trying to thread it down the entire length of the boot. Wrap the two cuts and the exposed wire with electrical tape (or slide braided sleeve over it) to restore a factory look, then reseat both ends of the boot.
6 Pull the wire into the cabin
Feed plenty of slack through the body pass-through, then reach underneath the dashboard with a flashlight, catch the wire ends, and draw them fully into the cabin. The driver side is easy; the passenger side is tighter because of surrounding wiring and obstacles, so work patiently. On the passenger side, pop out the plastic sail trim by pulling it outward until it unclips, which makes it easier to grab the wire and route it down toward the rear.
7 Reinstall the speaker and door panel
Connect the new speaker to your amplifier or head-unit wiring, mount it, and refit the plastic baffle with its four screws. Reconnect the rubber boots and reinstall the door panel. Repeat the entire procedure on the opposite door.
Pro Tips
- 💡 Slide braided wire sleeve over the exposed run through the boot for a cleaner, more factory-like appearance.
- 💡 14 gauge wire is more than enough for any door speaker; the follow-up confirms 12 gauge can also be worked through if you already have it.
- 💡 The factory service manual does not document this shortcut; the connector-clip opening and boot method are what make it a no-drill job.
- 💡 Take extra time on the passenger side, where the space under the dash is cramped by existing wiring.
