hi, like the title said, i have a question i was wondering, can i use a mono sub amplifier to power 2 subs at the same time? my original thought was no. but i see that there are 2 powered outputs on most of them -> or is this because of subs that have 4 posts? thanks in advanced, patrick
yes you can, its actually preferred over 2 channel amps. here's a wiring diagram from crutchfield: http://www.crutchfield.com/S-fznr3emGgfP/learn/learningcenter/car/subwoofers_wiring.html
you can power more than 2 subs depending on the amp and how you have the subs wired. Not unusual to see 4 or even 6 subs off of 1 class d amp.
