I have a sony xm 265gtx and want to know if I can use a dual coil sub

Dual voice coil. Positive from amp to either positive on speaker. Same with negative, then hook the opposite positive on the speaker to the negative on the speaker with a short wire.

If your sub woofers are SVC (single voice coil) 2 OHM each, then connecting one to each channel would make the amplifier run in 2OHM stereo Then again, if your sub woofers are 2OHM each, it would be better to connect both together in series and connect them to the BRIDGE specified speaker terminals of your amplifier making it run a 4OHM load into one channel. This will give you all the power the amp can give and still run stable. A 2OHM load into one channel will likely damage your amplifier. Do not forget to set the LPF (low pass filter)on if you are going to use the amplifier to run sub woofer/s. dreamsystems

lets do some diagnosis.. if it's possible, try hooking another known good sub up to the amp and see if that works. if it doesnt, it's an issue with your amp. if it does work though, it's an issue with your sub. or the wiring. if it's a dual voice coil sub, make sure you've got both positives hooked up to positive from the amp, and both negatives hooked up to negative from the amp. if you've accidently got positive from the amp going to positive of one voice coil then to the negative of the other, and the negative from the amp going to the negative of one voice coil then to the positive of the other, the voice coils will be pushing against eachother cancelling eachother's movements out. and this will fry the sub. OR the sub is already fried.

200W x 2 @ 4 Ohm
500W x 1 @ 4 Ohm

This amplifier cannot handle a load lower than 4 Ohms in stereo or bridged mode.

If the subs are Dual 2 ohm - You cannot wire a 4 ohm load with (2) subwoofers.

Only 8, 2, or 1/2 ohm loads are possible with (2) dual 2ohm voicecoils

Thanks!

it depends on the impedance of the subs-if your subs are dual 4 ohm coils then you can parallel the coils which will give you 2 ohms per sub- you could get max performance from your amp by just wiring the 2 ohm speaker load to each channel of the amp which will hit them with about 200 watts rms each. another way to do it is to wire the coils in series which will make each sub an 8 ohm load and then parallel them together and that will show a 4 ohm load -which you can use to run the amp safely in bridged mode. This will give you exactly the same amount of power to your subs as in 2 ohm stereo will. so with your amp being 2 ohm stable in stereo or 4 ohm stable in bridged mode- those are the numbers you want to hit for maximum"safe" operation

its a good amp but dont power ur amp at full put it at about half power

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.

Start by checking and making sure that you have excellent connections at power,ground, and signal. Depending on the voltage output of your rca wires if you are running rca's to your amp typicaly your amp gain should be only at half - you may be clipping the signal if you have the amp set too high. On your deck you will want your bass settings at only half -again too much boost will cause clipping at the amp. with all your settings adjusted and all possible connections checked- the only thing left to check is the compatibility of your subs in relation to the amp-by that im referring to the overall resistance-measured in OHMS that you are placing on the amp.Your amp is probably rated at about 150wattsx2 at 4 ohms or 200+watts x 2 into 2 ohms or 400-460watts into a 4 ohm bridged load. Look on the magnet of the speakers and find out if you have single coils or dual coils and see what the ohms(resistance) of each sub (or coils) are rated at- ideally you would want a set of dual voice coil 4ohm+4ohm per sub- that way you can match the subs better with your amp.---- Heres a scenario that may or may not apply to you- i see it all the time so im going to share it with you---- If you have a set of single voice coil 4 ohm subs and you are trying to run them wired in parallel to the amp in bridged -then that is why you amp is shutting down- you will have to wire the subs in series until you either get different subs that will yield an overall 4 ohm load -or find a different amp that will take a 2 ohm load - okay for now try wiring the subs in series and see if it still sends out an overcurrent light on you-good luck

HI DUDE ,, TRY CHECKING UR RCA CABLE ,, COZ IT MIGHT B UNPLUGED AT UR PRE AMP OR PLAYER ... OR CHECK UR SUB WOOFER WIRE INSIDE THE BOX ....

The sub you want is ONE single 4 ohm voice coil sub that is no higher than 500 watts in power but more than 350 watts. Your amplifier puts out the most power in the bridged state at 4 ohms so this is why you want a single 4 ohm voice coil sub. Also, you don't want to over or under power a sub so you want your sub to match or come close to your rated value of the amp. Good luck
