Amp bass cuts out cuts back on

Its a pretty simple principle...combine 2 speakers, and the ohm load gets cut in half. wire them in a series, and the ohm load doubles. for example, you have 2 subs that are 4 ohms a piece. if you combine both + and both - and put them to the amp, it cucts the load in half bringing it to 2 ohms. or, if you connect 1 + to the other speakers =, then run the remaining pair of wires to the amp, that doubles the load to 8 ohms. youll have to "double-ohm" it for dual voice coil subs. on each sub, you can do the same thing. either combine both + and both = into 1 wire to cut the rated load in half, or wire them in a series to double the load by connecting a + to the other coils =, and using the 2 remaining wires. once you have each sub wired the way you want it, then you can use the same rules when connecting multiple subs, by wiring in a series or parallel. it sounds confusing and its hard for me to put into works, but once you do it a few times its really easy. just remember the 1 rule...wire 2 coils parallel to cut the coils load in half, and wire it in a series to double it. hope it helps.
