I don't remember the specs but I would imagine the Q runs at 100 amps and may have a surge current near 300 amps. My q Spins up just like the fire rig but on my factory 80 amp alternator and one 650 CCA battery it runs fine. I can run it several times up to full speed. I can even run it while drivin...

My dad had a 100 amp "booster" charger like you used to see at a mechanics place. You can get them for arround 100 bucks. Check your local NAPA dealer or Sears and get a new charger. They are clean and supply plenty of power for the Q. That way you can have it indoors. I have a Q on my Jee...

They refurbished 2 of my BP100 speakers, by the way those speaker realy rocked. They had that problem, although rare. Have you noticed any sound difference with the new mags? The old vs the new Neos. They are much cheaper and look weak to me. Also, why the big sound difference in the older analog si...

Need some Grover Emergency Horns on it and a big fat Q!!!
