alright i am installing a wideband and have been splicing and soldering my display, control unit, test switch, and led. i needed to add a little extra length for the grounds and the 12v power and i didn't want to have to drive to an auto store or walmart to get a little spool of wire.

i do have a lot of excess stereo speaker wire left over from adding stereo components. i figured wire is wire, the speakers i figure are getting more juice than the wideband would require, so i said what the hell and used it. i'm thinking nobody does this 'cause of the substantial wire cost between the two but i'm not an electronics expert.

so, should i finalize the install and hook up the power to the wideband and run it or should i stop and get the traditionally accepted wire?

 

My concern would be the insulation around the wire itself. If you put the speaker wire on the inside of the car, I wouldn't worry. If the speaker wire is on the outside (engine compartment/underside of car) I'd be concerned about it's resilience to weather/wear & tear.

 

not so much weather as inside the doors they are pretty beat up.. but.. heat is not something these insulations will be able to resist.

 

alright, thanks for the information, i'll finish the install tomorrow (just attaching the grounds and the power source)...
