Question about Car Amplifiers
I have one kicker dual voice coil sub and 1-1 channel mossfit 300 amp and 1- 2 channel mossfit 300 watt amp i need to know by using both what posotive would i use and which negative and from what amp or one of each or what
Your best not using 2 amps on 1 Dual VC Sub.
Just use the 2channel amp and have 1 channel per Coil..
there will be a 'bridged' connection on both channels of the amp which should be outlined near the terminals.
If there isnt a bridge outlined then use;
+L and -R from channel 1 onto 1 of the coils and,
+L and -R from channel 2 onto the other coil
(or bridge the channels that way if that doesnt work)
worked a treat on my Polk Audio DVC 1200s
If you need more info let me know...

Scanman84: i would recommend using the 2 channel 300W amp to drive the dual voice coil alone. i wouldn't combine the single channel amp with the 2 channel. you can't tie the 2 channel outputs together & use that on 1 voice & attach the single channel amp to the other, plus there could be slight differences in amplification & timing which, could cause the sub to have minimal movement or cause a canceling effect which would reduce the spl, sound pressure level. if you need more volume use the lowest impedence speaker recommended by the amp's mfg & if you need serious volume, go with a higher output single 2 channel amp. just make sure you have sufficient wire size to handle high powered amps. example, 8awg wire is rated for 73 amps. also make sure the amp is well grounded with nut & bolt connections to the frame & that there is good ventilation.
