I bought a pair of Infinity Kappa 120.3 dual voice coil 4ohm 12" subs I am wondering what power/brand of amp would be best. A friend told me to get a 600 watt bridged at 4 ohm amp and run the subs in series/parallel. alot of this is foreign to me thanks for the help
The way your friend has it set up you would be sending 150 Watts to each coil. There are a lot of amps out there that would send more to each coil if you wired each input, two per sub, in parallel +2+, -2- and wired them onto each channel of an amplifier for a two ohm load per channel. But the best bet might be two purchase two monoblock amplifiers, one for each sub, and wire them in the same manner.
I just ordered this amp glasswolf any instructions for telling the tech installing it, do I just say I want em running in parallel at 2 ohms? and do I need a capacitor or anything and what does a subsonic filter do will I need one in a small sealed box?
