hi, i know this is prolly a stupid question, but how important is soddering wires that you have say when your installing an aftermarket stereo? could i just tie them together or is it best to sodder 'em good. i have used sodder before i just got lazy with my stereo and now it acts up and im wondering if poor performance might be b/c of no soddering...anyways thanks

 

solder and heat shrink is bast, but you can use butt connectors, they work well and you just crimp them!

 

shops just use butt connectors they dont solder. check your main ground for the radio.

 

ya it works again now..i resodered all the connections and got a good ground on it. it didnt seem to be working right still so i was out tonight and ran into a nice pothole, heard some scratching in the speakers and suddenly it worked again...duno why but it works now haha. o well good old rx7 fixes itself again
