[QUOTE="Steven, post: 60940, member: 544311"] I hop[e you knpow basic math skills Check the ratings on the amp, and on the subs. If the voice coils are all 4 ohm and the amplifier is only 4ohm stable i would connect it in a series-parallel configuration to do this, take one of the subs and wire the (-) on one voice coil to the (+) on the other. do this on both subs. Now wire the (+) terminal on the amp to the remains (+) terminal on BOTH subs. Do the same for the negative this will give you a 4 ohm load. If the coils aren't 4 ohms each use two of Ohm's Laws to figure out the best setup. the two laws you'll need are: in series R1+R2=Rt in parallel (1/R1) + (1/R2) = (1/Rt) to find a series-parallel setup you'll need both formulas. in the example above I used: (1/(R1 +R2)) + (1/(R3+R4) = (1/Rt) which works out to: (1/(4+4)) + (1/(4+4)) = (1/8) + (1/8) = (1/4) = 4 ohms [/QUOTE]
