Doing a setup for my friends chevy crew cab. First the equipment.
2- Memphis MS84D--8" dual 4 ohm subs in seperate sealed boxes at .3 cubes
the amp is a Sundown SAX-125.2 which does 125w x 2 @ 4 ohm; 200w x 2 @ 2 OHM; or 400w x 1 @ 4 OHM bridged.
The subs are rated at 100 watts each. So I can wire each one seperate and get either a 2 OHM or 8 Ohm load per channel.
Or I can wire both together and do a series/parrelle and get a 4 Ohm and bridge the amp.
What would you do?
or I guess I could run 1 coil and short the other one and run it at 4ohms and use both channels.
Series wire each sub first, connecting a single wire from one positive of a voice coil to the negative of the oppposite coil, now you only have a positive and a negative left on both sides measured at 8ohms, do the same on the other sub, now take the 2 positives you have and wire together at the amp in bridge mode in positive channel input as well as the 2 negatives under negative channel input, now you parralleled back at 4ohms mono to get the most from your amp, by the way Sundown Audio I just heard for the first time Sunday at an N.S.P.L event was really good stuff.

The tiny sealed boxes should make it okay to apply an overpower situation to those subs. Which is to say, I'd do as stated above.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
That is why I built such small sealed boxes cause I knew I was gonna be overpowering them.
built 1 box. (.3 cube sealed) tested it off my nissan in his truck. did not like it at all. Thinking of going ported (2 8's 1.1 cube tuned to 36 hz) Port would be 8"x1"x13.79 according to the calc on here. sound about right?
Really I think I may just not like 8's
