Definitely a 4 ohm load.If you do 1 ohm,that will send 4 times the current to the sub and you may end up hearing $150 blow out.2 ohm uses twice the power as 4 ohm and is still alot considering the power formula.watts=amps x voltage however amps are determined by voltage divided by resistance. 12 v divided 4 ohms is only 3 amps. 12v
divided by a 1 ohm = 12 amps when you go to crank up the power by turning up the volume,that results in even less ohms and more power.lol.Just use 4.Good luck! Greg

I have 2 18" kicker


First you need the OHM rating of the subs. Most of the time its on the box or the magnet on the back of the subs (normaly 2ohm 4ohm or 8ohm) And that of the amp. Most amps are 4 ohm output if its a 2channel and 2ohm output if its a mono. You NEED to know these cuz wiring it wrong can blow channels in your amp or cause it to cut "in and out"

I have 2 kicker l7 wanting to wire to best olm with hifonics 1200 mono


the best way to wire it is @ 1 ohm, but your amp has to be a 1 ohm stable amp. i'll attach some pics for you. this wiring depends on what ohm your subs are.

I got to 12 they are about 400 watts each what would be a good amp to put on it to lift the subs


Hello jeremymikjha,

Basically you want to match the subs in impedance and power.

With 4 ohm subs wired in parallel, the final load will be 2 ohms. Depending on how hard you want them to hit, a pair of 400 watt RMS subs will need an amp that delivers 600-1,000 watts into a 2 ohm load.

The enclosure you use will also make a big difference. A sealed enclosure will need more power. A ported enclosure will be louder with less power.

The Hifonics shown here would be a good choice for a sealed enclosure. It's rated for 1,100 watts RMS into a 2 ohm load.

http://www.sonicelectronix.com/item_17598_Hifonics+BXi+1610D.html

The Eclipse XA1200 outputs 600 watts RMS into a 2 ohm load. It would power the subs very well in a ported box.

http://www.sonicelectronix.com/item_17598_Hifonics+BXi+1610D.html

Somewhat less expensive but good quality would be one of the Alpine MRP series. The MRP-M500 is only $179.99 at SonicElectronix. It delivers 500 watts. It's big brother is the MRP-M1000 with twice the power. Be sure your subs are securely mounted or this amp will literally "lift the subs".

Hope this helps.

Wiring options


Hello chino2g,

For 3 DVC 4 ohm subs wired to a 2 ohm stable amp, your best option would be to wire all of the sub voice coils in series (individual 8 ohm loads) and then parallel the three subs for a final load of 2.67 ohms. There's really no other configuration. Here's the wiring diagram:

Got a 12"kicker L74ohm sub and sony xm-D9001GTR mono amp


Hello juan_penaloz,

The Kicker L7 has an RMS power range of from 50-750 watts and a maximum power handling capability of 1,500 watts so your Sony amp will power it OK. A more powerful monoblock like the Alpine MRP-M1000 or the Kicker 08ZX750.1 would provide even more power and could operate safely at 2ohms.

You have the voice coils wired properly for the Sony amp. It's OK to have the sub impedance higher, but you definitely do not want it lower than the 4ohms the amp is rated at in bridged mode.

Hope this helps.

Best amp for Kicker Sub


Hello dalex7,

The Kicker 08ZX400.1 would be a great amp for your subwoofer. It will work into a 4ohm load with no problems.

But you can buy an amp with more power, looks better, has a smaller footprint, and cost less than the 400.1. I'd look at the Alpine MRP-M500. Take a look at it here at Crutchfield. The M500 is also easy to install, runs cool, and is very efficient.

Hope this helps.

I have 2 kicker l7 12 dual voice coil subs.. i just friend a hifonics 1600w amp and am wondering if a kx 1200.1 kicker amp will be enough to power them they are 750w rms a piece .. can these be run at 1...


it all depends on the impendance of your subs if u have duel 4ohm or duel 2ohm, 2 duel 4ohm speakers can be wired at 1ohm to the amp, and with a kx1200.1 that would be pushin 2400 peak and 1200rms
if ya have 2 duel 2ohm speaker than you can only wire them to 2ohm and would be pushing 1200 peak and 600 rms with the kx1200, so if you have the duel 4ohm i would go with the kx1200.1 and if u have the duel 2ohm i would go with the hifoncs
