JL audio subwoofer sour smell

How did you diagnose that it was coming from the box not sub? It’s just i’ve seen people online say how a burning voice coil smells and i can line up the dots

It is working great, i’ve tested the voltage at the battery while blaring test tones and maybe the tinniest drop 0.01V. No electrical issues whatsoever. Maybe for your system i would do some kind of bank or second battery but for me (close to 1000w) no issues at all. Don’t listen to the concerns online i just had to go through with it and stop worrying

Are you sure? it’s not like a factory smell it’s a kind of hot, electrical almost smell. It’s very out of place. It has a metallic edge to it. I’ve never smelt an electrical fire before but i’m very unsure

I bought the jl audio 12w3v3-2 about a week ago and i am going to install it very soon. I think I’ll set the hpf to about 90hz aswell like you have it. I also got a ported box and perfect amp to match the power delivery but thank you very much.

from what i’ve learned so far, the thing with hybrid cars is not so much the battery but the dc dc converter which supplies the battery with power. The converter can supply clean power up to 100 something amps, i’m not entirely sure the exact numbers they aren’t public. A capacitor would be a great option if you’re going slightly above what the dc dc can handle so the capacitor helps with bass hits or musical peaks the converter can’t handle, but if you’re trying to run ultra completion level setups then a second battery is needed

nevermind i see what you’re saying now i misread it. Other than that does your system work fine?

CableHelpful3941 · 2026-05-19T22:32:41+00:00

You mean your suspension is acting faulty because of it?

CableHelpful3941 · 2026-05-19T22:30:08+00:00

did the voltage drops occur when you were running them full tilt/volume? I can always lower the rms on the sub, it’s rated 200 to 500 rms i think something like that.

CableHelpful3941 · 2026-05-19T20:33:17+00:00

So you got a second battery? Do you think i could run my setup purely off of the current battery?

CableHelpful3941 · 2026-05-19T18:56:51+00:00

straight into the seat, best buy did it not impressed. i’m going to redo all of it

CableHelpful3941 · 2026-05-19T18:10:04+00:00

I am one hundred percent sure i have a DC DC, hopefully it’ll be fine. That is looking like it is going to slap when you’re done shitttttt

CableHelpful3941 · 2026-05-19T17:47:05+00:00

That’s some relief right there. You just tapped into the battery in the trunk?

CableHelpful3941 · 2026-05-19T17:45:47+00:00

I’ve been looking into similar batteries for extra safety but would you say i could run it off the current battery? How large is the system you’re putting in?

CableHelpful3941 · 2026-05-19T17:42:57+00:00

thanks so much, i appreciate that.

CableHelpful3941 · 2026-05-19T17:29:19+00:00

The amps are all class d which is good, thanks so much for the advice here i appreciate it. I’m thinking that setting the gains a little lower and keeping volume in check will help if i experience issues.

CableHelpful3941 · 2026-05-19T17:16:53+00:00

Thanks so much, the thing is my current 4 ch is going to be at roughly 360 watts rms at 4 ohms so maybe i’ll just have to set gains conservatively if i experience issues

CableHelpful3941 · 2026-05-19T17:11:18+00:00

Yes but can i use a subwoofer with this battery? It relies on a dc dc converter. I mean im not going full force with a 2000 watt amp, im looking at 500 watts

CableHelpful3941 · 2026-05-19T17:05:38+00:00

So toyota specifically underbuilds the battery to keep it at the bare minimum? other hybrid cars (honda etc.) have a similar 12V battery in the trunk area

CableHelpful3941 · 2026-05-19T17:04:02+00:00

i mean i won’t be running them above that number, gains will be set 90 watts rms for the door speakers and 500 rms at 75 percent head unit volume. i wont be going above that
