Catchy title, no? Anyways I'm trying to wire my '89 LS for subs and I can't figure out how to route the power cable for the amp through the firewall. anyone done this before? How did you route the cable?

On the passenger's side there should be an unused hole in the firewall that is plugged up by a large rubber grommet...

This hole is directly ABOVE the hose the drains the condensation from the A/C evaporator....

There should be at least a couple openings thru the firewall to do this. although, a purist might forego using an existing hole because of possible quality issues and use an unused hole or make a new one. But that's too nitpicky IMO... an existing hole should be fine for most applications... especially if it is an unused one. the easiest way is to start in the engine bay and follow existing wires from something like the fuse box thru the firewall into the car... I usually use something like a wooden chopstick and poke in thru the opening (usually thru a rubber gommet) and check the other side to see where it's popped out. if I'm not mistaken, the big group of wires from the underhood fusebox/relay box usually goes thru the driverside to the cabin fusebox. the wires pop thru pretty high up on the firewall usually well hidden behind the dash.

good luck!

Beautiful! That did the trick . . . now if I can just wire up my system and drive 50 miles without my motor blowing up, lol. Seriously though, she's got problems (irregular idle, dies for no reason sometimes and won't start, low on power, service computer won't reset but doesn't seem to be throwing any codes . . .) some of which have been discussed before and I'm sure are in the archives, I just haven't had the time to diagnose/fix them yet. Anyways I guess thats what you get when you buy a 200,000 mile/20 year old car for a grand. Anyways thanks, Sam . . . you saved me from drilling holes
