I have an MB Quart Amplifier and a MB Quart Premium Series 12 inch woofer. It's a great system and keeps my GTI Euro.

I just wanna say I hate it when people ask how many watts it has or brags about ridiculous amounts of power. Half the time those high powered subs are drawing ridiculous amounts of power they don't need or just aren't efficient. A JL W6 has an RMS around 500 but will hit harder than pretty much anything.

Just putting it out there.
