A kicker 600.1 wired to a jl w7 10" sub? Will that work?


The kicker 600.1 provides 600 watts at 2 ohms and 300 watts at 4 ohms the 10" JL W7 has 2 1.5 ohm voice coils so you will have to wire them in series. Take about 1.5 feet of 14 gauge wire and connect the positive of one voice coil to the negative of the other then the positive and negative that are left go to the amp. Your impedance should be 3 ohms and that amp should work just fine.

I have 2 12 inch jl audio w7's with a kicker crossover and a powerbass equalizer 5 bands. i wanted to know if add a hifonics brutus 2100 d class amp to my subs at 1 ohm would it over power my subs. please...


Short answer: NOPE!

The Hifonics Brutus 2100 is stated to produce 2100 watts RMS @ 1ohm load. Most amplifier manufacturers overstate their claims. The 2100 watt output is most likely at 14.4 volts and not the 12.6 volts your car will actually be providing the amp.

But, even if the actual output was 2100 watts that would be 1050 watts to each 12w7. The 12w7's are rated at 1000watts RMS and 2000watts peak. As a MECP certified installer, any system I have done using 12w7's have had a MINIMUM of 1000 watts being provided to each speaker. My personal preference is to run 1500 watts each and keep the gains adjusted lower on the amp. Thus allowing the amp to run cooler and allow the additional headroom for those "show-off" moments!

My cone on my JL W7 cone is cracked, How can I replace?


JL has good customer service, and usually you can get a drop-in replacement core/coil/former/spider. Call/e-mail the techsupport listed on their website, or contact your local dealer for replacement parts/service.

Got jl300/2 amp confused which subwoofer sounds good


Hello drsubhakar26,

JL W6's will perform well with from 150-600 watts RMS. W7's with from 150-500 watts. Less expensive Alpine Type R's work OK with from 200-500 watts RMS. Either of the brands will sound good. None of them will perform to their full potential with 300 watts RMS. Powering any sub with a 2-channel amp is a compromise. A monoblock is more efficient.

Hope this helps.

Sub not very loud


Hey buddy your question caught my eye because i have a buddy that was wondering the same thing not so long ago-and im no expert but i have had my run with rockford fosgate amps and a few sonys as well. So first of all if you know fosgates well you know that they ALL put out more power than what they are rated at -example your 400 watt fosgate amp is rated at 400 watts but if you got it new than it came with a birth sheet that shows you how much its really putting out-im just throwing a number out there but its probably closer to 480 actual watts. Now you get the sony amp and it says its a 1000 watts but its all bs -it actually is rated at 400 continous usable watts- so the reason that its not any louder than the fosgate is because you bought an amp with almost identical power output. The other part of the problem is that you are limited by your speaker-you could buy an amp that actually puts out 1,200 watts and plug it right in to your sub and its going to probably blow within 30 seconds or quite possibly catch fire. The numbers when dealing with car audio that you have to pay attention to are the R.M.S. power ratings - never look at the peak or max wattage because its all bs and yea its all bs- As i was saying you are going to be limited by your sub because as it stands right now you cant put much more power on that thing without blowing or roasting the coil. All subs have a limiting factor as to how much air they can move- this is called X-MAX and that tells you how far the speaker cone actually moves from start to peak excursion- once you have supplied the speaker with enough power to reach its x-max then thats it -no matter how much power you put on it it wont move any more air than that-and you will create heat and distortion if you try and thats just begging for a blown sub. If you want it louder than upgrade your sub to something that will move some serious air like a jl audio w7 or orion hcca subs -those subs can get it on like dammmmm or easier than that get another sub and then your moving twice as much air at a fourth of the price of buying a balls out jl w7-anyhow good luck with that

Problem when hooking two 12 inch subs to one amp


the amp is no where near strong enough that sound you hear is called hard clipping and it will destroy your subs in minutes. depending on what model JL subs you have I can sell you a better amp.

Jl audio 12w1v2-4


500watts sounds about right to me,i wouldnt go any higher as you risk popping the sub and haveing a melt down in the coil section of the subwoofer.
