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!

Can you push a w6 with a 1500 phantom boss amp?


I can assume that phantom 1500 is a 1500 watt amp? but still the amp will have more than enough power to push a w6, w7,and even in pairs. Single w6 can handle 600 watts rms, thus you will need to turn the gain all the way down so that the speaker won't over powered and that can lead to breaking the sub.

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.

JL audio w7 is not working but not blown


Possibly the voltage spike/surge destroyed your subs. I am surprised you didn't lose your amp as well.

JL AUDIO 12W7-3 SUB


the rottem electronic smell is the voice coil burned up as well as the bad sound, isn't the 1st time i have seen a JL sub blown. not worth fixing buy a new one the cost is not that much more repair on them is 250 - 450 depending on how bad it is and only JL can do the repairs as they dont authorize repair shops access to their voice coils. however i can sell you a new sub with full JL factory warranty drop shipped to your door for about 475$ or I could do you a way better sub ( the baddest competion sub made in the last 5 years) an olympus 2412 dual 2 ohm 5000 watt monster that has user replaceable voice coil options and is killing the competition circuit right now for about $275.00 shipped. it will stomp 2 13 w7's into the ground all day long. 2 subs vs just 1

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.
