I use the "vampire" taps, called Scotch Blocks, all the time. I would agree that they are not as good of a connection but if you use the right size and put a dab of di-electric grease in there with electrical tape you will have no issues. they are much easier to work with.

Obviously personal opinion, but I've worked as a professional car audio installer for quite a few years. I can't count the number of vehicles I had to go in and fix after a do-it-yourselfer used those in a car. They all suck... I would absolutely never trust them in an environment that is subject to near mil-spec requirements, like in a sled. (massive temperature swings, humidity, extreme vibration, extreme cold, etc...)

If you are cutting factory wiring, good crimps or solder w/heat shrink only.

X2! I only use solder and heat shrink on all splices. I don't trust the Scotch lock blocks. With all of the vibration and moisture on a sled, soldering is the only way to go IMO.
