so i installed this system in not too long ago but just getting around to post it. i installed 6 1/2" Reference series components in the front, putting the tweeters in the A pillar. in the rear i have 6 1/2" tarantula series. i ended up getting one of the first 13" stealth subwoofer that they produced. To power this all up i have the rubicon 5.800 5ch amplifier. i only have about 80 watts rms, to the door speakers and 200 watts rms, to the woofer. its a great system, loud and clean. let me know what you guys think.
