What ohm should i wire my subwoofers to my amp!?

Question

Hey, i have 2 MA Audio HK120XC Dual 4 ohm voice coal subwoofers, and a Kenwood KAC-9104D

1800W Max, Class D Monoblock Amplifier, plus a scosche 1400 wat max 700 watt rms amp wiring kit, and a MONSTER 12 gauge subwoofer speaker cable up to 1600 watt power handling. what ohm should i wire my subs to my amp to. i want to get the best sound! should i wire my subs at 1 ohm to my amp, cause it is 1ohm stable at 900 watt, or should i do something else. Are my wires big enough to do all of this? i just need to know cause i build my subwoofer enclosure and i need to know how i should wire the subs to the box to the amp!

Answer 1

yes. wire the subs to 2-ohms each... then putting them to a mono-block amp will create a 1-ohm load....that is the way that you will get the most power out of that kenwood. for wiring diagrams check out rockfordfosgate.com or the12volt.com

Answer 2

12 gauge wire can only do 41 amps thats little over 500 watts at 12 volts

I would want something bigger or just run two sets of 12 ga wires.

If you have 4 ohm speakers why don't you wire them 4 ohm so you don't burn them out? Sounds like you have a c**p load of power in amps you don't need short cuts.

Answer 3

How you load an amp determines the amount of power out.

There is a trade off though, the lower the impedance (ohms) the more power is pushed as well as higher distortion and more heat is generated. The excessive heat will shorten the life of the amp.

For best overall performance, it's far better to get a higher powered amp and load it with 4 ohms than a lower powered amp and force it to push more power with a lower impedance (2 or less ohms) load.
