Just had my 10w6v2 blow, ripped at the foam to cone area and I don't even crank the sub volume usually... although the stereo's cranked. Giving the 10w6v2 one more try in case that was just a lemon.

 

OK I got ya.

Actually it was pretty easy. What I did is use the wiring breakdown thread here

https://www.myg37.com/forums/audio-v...breakdown.html

Cables 23, 24, 25 ,26 on harness B41 are a low-volt signal coming from the headunit. Splice into those and you have the inputs for the subwoofer amp

I also found a picture that showed the harnesses and cable numbers on this site but I cant find it right now, maybe someone else has it saved or knows the thread it's in.

 

Must have been. I wont argue that JL is pricey, but they are definitely a quality product.

 

Another user asked me to post my amp settings so here they are. This is for a JL Audio 500/1v2

Infrasonic Filter mode - On
Infrasonic Freq - 19

Q - 1.6
Center Freq - 45

LP Filter 24db
Filter Freq - 75

The gain (Input Sens.) I set by playing a 50hz test tone and setting the voltage to 31.6

I actually turned down the gain a little from that because it was just too loud for some songs

On the headunit I set the bass for -2 and treble for +2

 

Some information I found on the subject.


I would highly recommend having someone that knows what they are doing to tune the amp. You can follow the gain setting tutorial on JL's website, but if you have the gain too high and play your music too loud, you risk damaging your amp and/or subwoofer.

Here's a few info on some of the settings.

Infrasonic Filter (also known as subsonic filter): Some amps have an on/off switch like the JL, others have a certain frequency. If you are going with an infinite baffle or sealed setup, I'd leave it off. If you have a ported setup, you set it according to the tuning frequency of the enclosure (usually a few frequencies below is ok). I had a Kicker ZX and I believe the SSF (subsonic frequency) was defaulted to 25 HZ. Basically, any frequencies beyond that frequency are cut, not completely, but enough to where it where it helps prevent damaging the subwoofer. If your box is tuned to say 35 Hz and you play a 16 Hz note (rare, but some tracks, like bass tracks will have that), the sub will bottom out. Think of a subwoofer as the car's suspension. What happens if you hit a big dip and you're lowered? The car can bottom out. If it does that constantly, your suspension is damaged, and in the case of a subwoofer, it would need a recone.

The Boost, is for the bass boost. You adjust this BEFORE setting the gains, but I always recommend leaving it at 0 or off. Yes you get more bass with it on, but all it does is boost a certain frequency, and that depends on the amp. Image a straight line and on the line the frequency range is from 0 - 120 Hz. If 45 Hz gets boosted, it would be like dragging that 45 Hz point on the line upward. The more you turn it up, the more it boosts the frequency, and other frequencies get boosted as well, like a bell curve. The problem with this is, that it's only boosting a few frequencies and not the entire spectrum, so if you want more output, turn up the gain instead, or if it is at its safest level and you have enough power going to it, redesign the enclosure or get a new sub.

The LPF or low pass filter is the frequency you set where the subwoofer will not play above those frequencies. What you want to do is match this with the HPF, or high pass filter that the midbass speakers will be playing.

The input dial, or gain, allows you to adjust the amount of signal an amplifier receives. It is NOT volume ****. Although the loudness of the sub increases and decreases by adjusting, what you are really adjusting is the sensitivity or signal of the amplifier. Turning the gain down results in less wattage, turning it up results in more wattage. If you want to adjust volume, do it from the head unit.

Hope this info helps, and hopefully I didn't make it too confusing.

 

Thanks for the info Red, TBH I just set the gain properly but the rest was mostly by sound.

I don't like using the bass boost, but with our cars we pretty much have to use the stock headunit and that limits the settings we can adjust vs an aftermarket HU. Same goes for the LPF, I have no idea what freq the interior speakers cut out at so I had to go by sound.

I will try turning off the infrasonic filter and see how it sounds though. Would you share your amp's settings with us, you seem to be a lot more knowledgeable than myself.

 

Sames as yours, except 12db filter slope and Infrasonic off. See: http://mobile.jlaudio.com/pdfs/Switches_Knobs.pdf form more info on the settings.
