Cables And Speaker Wire


Recommended Posts

Posted

Tommorow I am gutting the inside of my truck, putting in new speaker wire and just doing a general cleanout of my entire interior. The only thing that I cant really figure out is how to run the RCA cables from the back of my amp and down to the floor. What part of the dash do I need to take off to run this thing? Right now my head unit is sticking halfway out of the dash lol.

Ok, I'll take a wild guess. I'd say you probably have a 2002 GMC Z71 4x4 Extended cab, 5.3L short box, black. For that particular truck--a true classic--here's how I'd run the wires.

 

If you're going to put an amp in back, by the subwoofers, you're probably gonna want to run power for the amp on the driver's side, under the door sill trim. And you're gonna want to run audio, RCA and/or speaker wires, on the passenger side, under the door sill trim.

 

From the radio pocket in the dash, you will find it difficult but possible to fish a wire from the radio pocket at the back of the radio space, to the right, behind the a/c ductwork, and over to the right where it will be visible behind the glovebox once you've released the glovebox door and let it hang down toward the floor.

 

From there you'll put a few cable ties to hold it up above the glove box space, inside the dash and above the glove box, all the way to the right edge of the inside of the dash, and you'll descend toward the door sill area inside the passenger kick panel (just forward of the door).

 

You can probably get away without removing the passenger kick panel, just tuck the wire in all along the floor all the way up to the firewall, and then pull it back behind the kick panel so that:

a) it exits at the top at the base of the glovebox door, and

b) it exits from the bottom in a way that guides it into the wire raceways that are exposed once you've unsnapped and removed the door sill trim.

 

Then just feed the wire into the exposed raceways and out at the back seat area after you get past the end of the door sill and for a few inches run under the kick panel behind the back door, and then finally out into permanent view, under the back seat, where the dual 10" JL Audio downfiring subwoofers and 500W RMS power amplifier is located.

 

So what kind of truck do you have, anyway? (The above instructions would probably work for any full size GM truck since 1990.)

    • Yep! This should be a pin somewhere as @pgamboa really dives into all of this. Thanks for reposting the link!
    • I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.       
    • Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.  
    • I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires. 
    • Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉
