Paco's build as of August 4'th. Jake, Steven, and Paco stayed late last night to get this beast playing. There is still a lot of work to be done but as of right now the system is absolutely brutal. Twelve Obsidian Audio D2's in a 2:1 ratio 4'th order bandpass being powered by two Sundown Audio 4500D's. There are also eight 16 volt batteries in the back being kept up by a dedicated 16 volt high output alternator under the hood.
