Have a jl audio 500/1 the red light blinks and no other light turns on. whats the problem with it?


I think you might have your remote turn on from your deck to amp hooked up wrong check that out!! I not are you familliar with the mr. butterworth crossover JL developed for that series of amp? Just like its big nrother the 1000x1 class D the built in smart crossover has many built in pretect modes. If your subs are drawing to much power it shuts down if they draw to little of ohms or to many but that 500 is 1 ohm stable so download the crossover settings from JL and go from there

JL W6 ohm wiring issue


Parallel , all positives together , all negatives together . With 4 ,4ohm voice coils in parallel you get around 1 ohm .

Shuts off when the volume gets turned up didnt do this wen new


A mono amp usually can handle only two 4 ohm subs. You see when you hook up two subs in parallel it drops the ohms too 2 ohms and 3 in parellal drops it to 1 ohms overheating the amp and cause power failure. Unless you bought a Mono amp thats 1ohm stable. But still I've seen cheap 1 ohm stable amps not last long. Also possible your subs are fried too check them with a multimeter and measure each sub ohms.

I hooked up my two 10 inch JL Audio W3v2 2 ohms to a mono JL Audio 500.1 amp and the subs will not work. I have the subs wired in a series. I then hooked them up to my friends amp and the subs worked. Any...


try one at a time. if they work then try hooking them up differently. if none work, then check to see that your amp is not in protect mode. if amp is ok, then check to make sure you have your rcas connected to your amp. in other words, re-check all your wiring. if still nothing, try your amp on your friends car and vise versa.

How do i wire two audio pipe dvc woofers to this amp. do i use all four terminals on da amp. jl audio 500.1


Hello smoovek2008,

The JL Audio 500/1 outputs 500 watts RMS into a load from 1.5 to 4 ohms. Whether your subs have 2 ohm or 4 ohm voice coils, they should be wired in series and the subs paralleled to the amp. The final load to the amp will be either 2 ohms or 4 ohms, both of which the amp can handle. If you parallel the voice coils and then parallel the subs, the final impedance will be either 0.5 ohm or 1 ohm, both too low for the amp.

You can wire each sub to a separate set of terminals or both to the same set. The terminals are connected internally. It doesn't matter which of the +'s or -'s you use.

Hope this helps.

How 2 wire 3 jl audio w6 v2


Hello mikey4569mky,

Unless your amp is stable below 1 ohm, there's really only one wiring solution. And that is to series the voice coils making each sub 8 ohms, then parallel all 3 subs to the amp for a 2.67 ohm load. If you parallel the voice coils and then parallel the subs, the impedance will be 0.67 ohms, much too low for most amps.

You could parallel the voice coils and then series the subs for a 6 ohm load, but the amp won't put as many watts into a 6 ohm load. Most are optimized for 4 ohms or 2 ohms. And it's not good to run subs in series anyway.

Here's the wiring diagram.

Hope this helps.

Low ohms light flashes and bass distorts at high volume


Sounds like you need to invest in a capacitor. Those are used when subs receive a bass spike. You just a need a 1 Farat Capacitor (1,000 watts) ran between the head unit and the amplfiier to fix your issue. Also, try reducing the volume gain to half gain and low pass frequency to half gain; this will increase your clarity and make your amp less hot. This may fix it without a capacitor. Also find out what amprage your alternator is. Your alternator may not be designed to run the amplifier. Most alternators are 200 amps now if they are gold plated.

Hope this helps

Jl audio 500/1 amp low ohm light at high volume


I would try running the subs in parallel. Pos to Pos Dual Voice, Neg to Neg Dual Voice. Then Run + to + stereo - to - stereo on both channels.
So you have + and - running to one channel and + and - running to the other channel.
Also your LPF filter could be set too high.

Can i wire 3 jbl gto1204d subs into 1 jl audio 500/1 amp


You can connect them in a series/parallel configuration. Put two of them in series and then connect the last one in parallel across the two in series. This would give you an impeadance of around 2.7 ohms. Only do this if your amp is stable at 3 ohms or less. I am not familiar with the specs of your amp. If your amp is only 4 ohm stable you can not do this.
This would also give you half the power on the two subs in series as the power for the one that is parallel. The two in series would be sharing the total output signal, where-as the one in parallel would get the entire output signal from the amp.
if you were to connect a fourth sub woofer in this configuration it could give you a 4 ohm load, by adding the fourth sub in series with the single sub that is in parallel. or in other words, yu have two sets of 2 sub woofers each in series. That gives you two 8 ohm loads (two 4 ohm subs in series is 8 ohms). Then you take the two sets of subs and parallel them (two 8 ohm loads in parallel equals 4 ohms).

If i had a picture to show you it would make sense, two subs in series that are in parallel with two subs in series.

Make sure that you have the subs wired in a 4-ohm series and not a 8-ohm load
