    Did you install the system yourself? Have you checked the amp's ground wire connection recently for corrosion?

SOURCE: i have polk amp that is powering 2 12' subs but

you must check your wiring from head unit back to subs even take subs out of box to make sure no wires are lose 99.9 of the time a wire has come lose which can be bad if your bridging sups as it changes ohms with 1 or 2 subs hope that helps oh and check volts from you batt and check volts at fuse spots and after fuse to make sure your geting at least 12 to 14 volts cheers i just had a ***** of a prob my subs worked but **** bass found out head unit sub out craped out

SOURCE: if the power light on this 1200.1 polk amp turns

i had an amp that did the same thing your amp should not be doing that i dont know how old it is but mine had internal overload switch in it which kicked on if the amp was getting to hot and in my case i would say it was because of i had the amp bridged to a set of of some 100rms 4ohm speakers very nice speakers but by bridging the amp i was over loading the ohm load to the speakers and that was cause of my amp light staying the color that its was it was an old alpine amp with duo B circuitry but i hope you get your situation with this amp straited out check your contecions and if its bridege make sure the amp itself is not over heating cause that can be a problem you dont want mess with that.

SOURCE: Optimum set up for Polk Audio PSW 10?

Run 2 RCA cables from the two Purple connections on your Receiver (Labled "PRE OUT SUBWOOFER") to the Red and White connectors on the back of your Sub (it does not matter which Purple connecter you plug into either the Red and White)

Set the volume control on the Sub to about 75%, and keep the power switch in the "ON AUTO" position. To set the Low Pass value, look at the back of one of the front speakers in your setup, and note its frequency range (will look something like 100Hz - 17kHz). Set the Low Pass at a value slightly higher than the low value on the back of your surround speakers.

To set the phase switch, stand in the middle of the room with some music on (something with some bass, but not over the top bass) and have someone switch between 0 Deg and 180 Deg. Listen for which setting sounds "Louder and Fuller". This is the one you want. You will need to do this each time you move the Sub, as its position may change its phase in relation to the rest of your system.

Good Luck!

Wire 2 sub 4ohm


I am assuming these are subs, you didnt say, but that is my guess. do you want bass, or do you want to take it easy on your amp? do you have a terminal cup on your sub box, or just wires going into the box to the speakers? take it easy route: wire positive from amp to positive of one speaker, negative of amp to negative of the other speaker, with a jumper wire connecting the negative of the first speaker, to the positive of the second.
more bass route: run seperate positive and negative wires to each speaker, making sure to maintain proper polarity.

you dont want to connect both of those amplifiers together. You could run them separately to separate subs or the jl to your sub and your alpine to your front speakers. But you dont ever want to mix and match amps to the same sub. Even if you had 2 jl500/1's you wouldnt want to just hook them up together. Because they both have to be putting out the exact same amount of power. Which no 2 amps are ever exactly the same. Some companies make bridges to properly connect 2 exact amps together. I Hooked up 2 JL 1000/1's to each voice coil on a 13.5 W7 and i smoked the sub. So i definitely dont reccommend doing it unless the amps are conneccted to separate things.

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.

I have 2 6x9 speakers up front 4 6 1/2 3-ways


Hello rjmiller4039,

Although amps with 5 channels are pretty rare, you can get one. Alpine, Boston Acoustics, Infinity, JL audio, MTX, and Polk all have 5-channels ranging in price from around $350 up to around $1,000. The Alpine PDX-5 will output 75X4 watts RMS for the front and rear stereo channels and 300 watts to the mono sub channel. It is priced at $599.99 at Crutchfield.

Hope this helps.

500/1 settings to run jl13w6 v2 d-4


Just had a look at both amp and sub on the JL Audio website. The amp runs from 1.5-4ohms. 4ohms at 14.5V. The sub is running dual 4 ohms coils. That's what the D-4 means. So should be an easy set up. The amp has two mono outputs, so one for each coil. It looks like the perfect wattage to run the sub real nice.

I bought a 500/1 jl audio amp and also a w7 10 sub


if its cutting off and right back on then check your ground and your power wire makes sure both are connected good and none of your fuse's are blown, either that or you got a wire hooked up backwards in the sub.. but my guess is that the sub is hooked up wrong... that sub should be hooked up in a series or in parallel,

ok if your running just one speaker, it should be hooked up like this and 2 speakers are a different way...

this is parallel :pos to pos , neg to neg, then one wire coming from pos on sub to pos on amp then neg on sub to neg on amp but bridge the amp on your amp should be 2 pos and 2 neg in two different channels take the pos off the sub into the pos on 1 channel and then the neg from sub to the neg on the other channel,

this is series : on the sub it will go pos to neg then the other neg and pos will go to the amp, but make sure the pos and neg r on different sides of the sub, dont hook them both to the same coil

if your need more help give me your email and ill send you a pic of how to do it...

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.

This is a single channel amp that puts out about the same power at 4 Ohms or 2 Ohms. If you have two 4 Ohm single voice coil subs, then wire them parallel (both pos and both neg) to achieve 2 ohms. If you have two dual 4 Ohm voive coils, you want to do a series - parallel config to get to 4 Ohms (voice coils in series, then parallel the subs). Same with DVC 2 Ohm subs, series parallel = 2 Ohms. Do NOT go below two Ohms. You will blow the amp (actually, it'll do 1.5 Ohms). If you happen to have 2 Ohm single voice coil subs (not as likely) run them in series. Most amps will put out about twice as much power at 2 Ohms vs. 4, but this amp is designed to put out about the same. Hope this helps!

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.
