Big Problem with sub and amp..

[mtparker18]

Hey guys.

I bought a JL audio 12w3v3 back in october and bought a 500.1 amp for my truck.

Saturday I bought a second w3v3. Since I put it in if I get my stereo to a certain volume I hear a popping noise(which i think is out of the new one) and the low ohm light comes on for about 1/4 second on the amp and it goes back on for a sec and so on.

Any one know what I'm doing wrong?

Amp is a 500.1v1

and both subs are 2 ohm.

Thanks!

it might be something internal within the sub. or bad connections. try just playing the one you just bought by its self. and see what it does.

what ohm load is the amp seeing?

 

[johnnyvolcom5 10+ year member]

are your w3s 2, 4, or 8 ohm coils, and how are they wired?

I only ran it on the new sub...worked fine.... now what?

2 ohmmmssss.

Amp doesnt like the ohm load.

well your at 1 ohm if you have two 2 ohm subs wired in parallel.

Amp doesnt like the ohm load.

So how do I get it to like it? lol

well if im reading this correctly I dont think you can.....you'll need a amp that is stable down to 1 ohm.

isnt that jl 1ohm stable.

 

[johnnyvolcom5 10+ year member]

i think its only 1.5ohm stable. He didnt really specify if it wsa a jl amp though it just says 500.1 but i am assuming its jl.

Yeah its a JL amp. I was told by 3 shops that it would work?

 

[johnnyvolcom5 10+ year member]

Rated Power: 500 W RMS @ 1.5 ohm - 4 ohm (11V-14.5V).....that was taken off the JL website. Since you have two subs now your final ohm load changed from 2 to 1 ohm. As you can see your amp is only rated from 1.5ohms-4ohms. Sorry man i think the shops were wrong. You will need a amp that is 1 ohm stable.

Retards. All of you.

The amp puts out the SAME POWER @ 1.5-4 ohms.

So tell me WHY he needs a new amp for his two 2 ohm woofers because he can't run that one at 1 ohm?

Run it at 4 ohms and you have the same power.

Ignore the impedance in this image (no one has an image for 2 2ohm in series), wire your subs like this though.
