Im use to be a coaxial man but as of recently ive been trying raw drivers just for kicks. I ordered a pair of audiopipe speakers with the sealed back (8 ohms) and these babies scream! At first i had them bridged on my 4 channel amp (400x2 @4 ohms), but i didnt like the mono output it was putting out. It sounded real distorted at higher volumes. So eralier today i just wired them as if they were 4 ohm speakers and gave them their own channel. The output is now stereo and sounds 10x better. Wish i would have done this sooner. Cant wait for the tweeters to come in!
