kinda odd i think..memphis subs

yes if you getting same sound from one sub as you are with two then there is a problem.

let me clarify that one....both subs have the same volume independently, together they are obviously a bit louder

how exactly do i do that?... they should be at 2 ohm per sub.....but, then again i am rather new to this.
i have a dmm and i used it to set the gains - the rest of the car sounds great btw....

put the dmm on ohms and check what each sub is reading by unhooking the speaker wires at the amp and checking those speaker wires with the meter.

would .25ft cu over spec make that much difference in a sealed box?

As said above, turn your DMM to ohms, and then touch the DMM leads to the amplifier where the speaker wires connect. You should be able to just touch the DMM leads directly to the connection blocks on the amp, no need to unhook any wires. This is the easiest method, and insures you are measuring exactly what the amplifier is seeing because you are measuring it at the amplifier.

did you check to see if they were out of phase???? I would check that first.

 

[audiomobil2008 10+ year member]

it could be that or the box or it can be many things
