You most defianatley cannot connect these three sub to that amplifier, or any 2 channel amplifier for that matter. In total between those three subs you have four voice coils all totaling an impeadence of 0.66667 ohms your amp is only stable at 2ohms bridged. However, you could run the two 12" sony's through one channel and the 2 voice coils of the 15" in the other and they would work, but would give a lousy power output as they are not bridged and not recieving enough power individually.

Actually you can wire these 3 subs to this amp provided that the amp sees a 4 ohm load from all speakers. As you have two single voice coil 10's at 4 ohms and a 15" with dual 2 ohm coils, this is possible. Your amplifier has a mode called tri-mode which allows you to wire 3 speakers to it IF the load is 4 ohms or greater on all channels. Hook the two 10's up to the stereo channels of the amp. Next wire the dual 2 ohm coils of the 15" driver in series, this makes it a 4 ohm load. Connect the 15" to the bridged outputs of the amplifier.

Oops, did not catch my own mistake. You connect each 10" to each channel of the amp. So this means that you are in effect running the 10's in stereo. Next wire the sub to the bridged terminals of the amp.

What is the Bridged Terminals?? So connect each sony to each channel,,and connect the 15" to the Bridged thing?

The bridged terminal is the positive terminal on the left channel and the negative terminal on the right channel. Just make sure that you connect a positive and a negative of opposite coils on the 15", then take the two remaining terminals and connect them to the bridged channel.

Wire the 15" sub according to this diagram. This is a series circuit. Option 2 (series) = 4 ohm load
Voice coils wired in series
Recommended Amplifier: Stable at 4, 2, or 1 ohm mono |  |
