I need some advice. I have an Alpine 3549 300 Watt mono. I also have a 1.5 cubic foot box. I have 2 choices.
1. 1-Eclipse 10" DVC both 4ohm = 2 ohm load
or choice two
2. 2-Older MTX Road Thunder PRO's 8ohm each = 4 ohm load
What should I do? Run the 1 Eclipse in a 2 ohm config or the 2 MTX's in an isobaric & a 4 ohm config? The box was designed for the Eclipse but I have the other 2 just laying around and thought I might just use them. I know that the box design for a iso config is usually 1/2 the normal size. How would the box do at normal size? Thanks for any help.

Eclipse or Road Thunder? Hmmm.... 
------------- Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Hold the bus, if that is the old 3549 mono amp, it was not stable to 2 ohm mono, back to the subwoofer drawing board you go.

Use the Eclipse and use one coil only on it.

I don't think that is correct geep...but I do not have the stats to back it up...so here's a grain of salt to go with it. ------------- The Flakman

Thanks for the posts. I have ran the Eclpise for a couple of weeks @ 2 ohms and had no problem. The amp does get warm but no thermal shutdown. But out of these two choices which one will have the most "bang for my buck".
