I have a MA Audio Amp rated @ 1100 watts x 1 @ 1 ohm and 2 Audiobahn 10" subs rated @ 600 rms a piece. I assume to run these subs in parallel and hook it to the amp. Approximately what spl would I get. I will be putting these in a 95 4-door explorer xlt. Subs will be in a dual ported slots box with a divider.
