ok heres the answer: yes heres how : run two wires from the posititve lead on the amp to each port on the subwoofer box and do the same to the negatives so that in reality there are a total of 4 wires running from the amp. this will be a parallel setup cutting the ohms down to 2 a peice. then inside the box wire the subs up parallel according to the manufacturer and that will once again cut the ohms from 2 down to 1. any question?
In case you're still confused, 2 4ohm DVC will give you 1ohm load. So you should be able to use 1ohm stable mono amp with them. To get your 2 subs down to 1ohm, wire pos to pos and neg to neg on each subs. Now you take the pos and neg from each sub and connect them to the amp's pos and neg. This will connect both subs in parallel, thus giving you 1ohm.
If your amp is 2 channel, you can either attach each sub to the separate channel (make sure it's 2ohms stable in stereo mode), or you can bridge the amp and use it as mono (assuming it's 1ohm stable bridged). Either way, it'll work.
if thats true why cant i run my 2 12" 1241d type r's with my mrd m501? i was told that i could only hook up one sub to that amp and i needed to get another mrd m501 for the other sub. is that true?
Jimbo911, your mrd m501 amp is 2ohms stable. So to connect your 2 subs, make sure they both add up to 2ohms load. Let's say your subs are 2ohms DVC. Connect each voice coil in series so that you get 4ohms per sub. Now connect them together to get 2ohms total. It'll work fine in that configuration. If however, your subs are 4ohms DVC, then you can connect them in series to get 8ohms per sub and then parallel them to get 4ohms. Now it'll work as 4ohms load on the amp. Your goal is to match the subs' ohms to the amp's ohm requirement.
