Is this common practice?
Hello,
I recently had a 4 channel amp installed at a local Circuit City. Instead of running new speaker wire from each speaker back to the amp, the installer ran new speaker wire from the amp and patched it into the factory speaker harness under the dash (the factory speaker harness is no longer connected to the speaker outputs on the head unit). Is this an acceptable practice? I am getting a significant amount of engine noise but I don't know if the two are necessarily related. It seems like a lazy way of doing things but I don't know enough about it to know if it's a bad way of doing things, i.e., if I should expect new wire to be installed from each speaker back to the amp or if this in and of itself could introduce a ground loop (it's a 97 Toyota RAV4 if that makes any difference). Any experienced opinions are greatly appreciated...thanks! Bruce |

As long as the connections are done right, it doesn't hurt anything. Why
run new wire into the doors when there's a perfectly good wire already there? It's very unlikely that this is related to your engine noise. I'd take the car back to Circuit City (or a different Circuit City) and ask them to track down the noise. "Bruce" wrote in message om...

Instead of running new speaker wire ....... patched it into
the factory speaker harness under the dash Is this an acceptable practice? No (unless your talking about a 20 watt per channel amp, which would be pointless given your new head unit has at least that much power. Here's what you do. Go back to the sales department. Tell them you have a a 75 x 4 (or whatever amp) Ask if 20 ga wire (your stock wiring) is adequate, or should you purchase heavier wire. After he sells you on the merits of thicker wire, ask to see a mananger. Have the salesman repeat what he told you in front of the manager. Pull out your receipt and ask why your amp was installed the way it was. I am getting a significant amount of engine noise but I don't know if the two are necessarily related.

Can you put this in terms of reference vis a vis the actual effects of using the "20 guage" wire versus the 16 guage ? In short, I think you will find that such a short run of factory speaker wiring will have little in the way of "adverse" effects, even when using a 75w amplifier. - RG |

I cant say how common it is. I personally have never done it this way.
I run generic 12 gage directly from the amp, to the doors through the factory rubber gromets. I dont think this is the source of the engine noise. From my experience, all my noise problems were picked up though the RCA cables. Garrett Bruce wrote: Hello, I recently had a 4 channel amp installed at a local Circuit City.

Not all cars have grommets. A lot of Fords and all of the VW's I've owned
have molex plugs which can be a bitch to run wires into. A Honda has grommets and you usually need to take the doors off to run wires into them. Almost every shop I've worked at or shopped at runs the wires to the existing wires in the dash. With such a short run it won't hurt anything. Paul Vina "Sanitarium" wrote in message ...

X-No-Archive:yes
That was a good idea, I'm gonna save that one tucked away for next time I am in a situation like that. That would be a blast (yeah I'm cruel like that) because they do try and cut corners in the install area and sell you too much stuff. ~«©¿©»~ http://home.comcast.net/~wegetourmai...ome.html-.html No. Try not. Do or do not, there is no try. Max "Quigmeister Quigolator Quiganology" wrote in message ...

Did you pay to have the wire run directly to the speakers? Probably not, most
shops like CC or BB will do it if you want them to...but they will charge extra for it. And unless your running an insane amount of power, the 20 g. wire will be sufficient for what it is doing. |

I worked at CC and they will charge to run new speaker wire to each speaker...

I see... My accord does have grommets, large soft rubber ones that
easily accomodate additional heavy gage wire. They are difficult to access, but I was able to do it with with a little elbow grease and without removing the doors. Heres a pic...

And I said usually, not always. Yes you can do it with the doors on, but it's about ten times faster with them off. Paul Vina |
