butt connectors are OK, but I prefer not to use them under dash. When re-installing a radio, a butt connector that has a bad crimp can malfunction and you will not know it until you have the job all zipped up and THEN you realize you have lost a connection (that sucks) In addition, wires are sometimes not tight in a butt connector. n00bs often dont have the proper tools for a good crimp. By not having a good crimp, the wires arent secure in the connector, they can arc and short, heat up and eventually fail or worse cause fire. Solder rarely fails (if done correctly and not cold soldered). Id ALMOST agree that twisting a wire together is superior to butt connecting it if not for the strength of a PROPER butt connecting joint. As far as the tape thing goes.. Electrical tape is infinitely flexible, and more heat and water resistant than package tape and will take prolly 1,000 times more abuse. Therefore a better insulator //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif The last place in your car you want a short or arcing condition is under the dash. By the time you realize its bad, its often too late and the fire department is en route to put out your car-b-que.
