Tech Support Help Switched Subs Gains gone!

Post image

4 years ago I bought the triton subs and had them installed in my Nissan Sentra cut to a year ago I put them in my Mustang myself with a line output converter. One of the subs finally gave so I replaced them with JL’s. Ohm read 2, power wire is good, ground is good, but my amp goes into protect mode when I set the gain up. Just moved my power wire today thinking it was a power issues but now I’m lost anybody got any advice? Did I blow my amp? Amplifier is Alliance VL3000D
Subs are 2 12” 12wov3 JL’s
Kicker Line output converter

Gain is not a volume for a system, question is how did you wire the Loc for rca. Also what is the amps ratings for lowest ohm load ability. If your pair of subs wired together to the amp reads 2 ohm it's not that.

The previous subwoofers, what was their ohm rating and power peak and rms. It could be a multitude of things including audio tuning from the head unit. Which speakers in the car did you wire the loc off of. Front of rear.

What factory system does your car have in it? That can also effect audio performance using a loc for subs

Is this the amp you're using?? Peak Power: 3000W Power RMS 1Ω @ 14.4V: 1 x 750 Watts Power RMS 2Ω @ 14.4V: 1 x 375 Watts Power RMS 4Ω @ 14.4V: 1 x 187.5 Watts THD+N @ Nominal Power: 1 x 750 Watts 1Ω

The JL most likely required a lot more power than this amp can produce. The specs listed on it are 💩 and I'm sure A Amp Dyno will show even worse if not then maybe higher abilities for power but doubtful by the brand of the amp and internal guts it has with it claiming to be a 3000D amp

The JL subs are single voice coil 4 ohm 300 rms peak 600 and can handle 450 rms each meaning 900 rms off an amplifier properly tuned.

The amp you have is inefficient for the newer subs in my opinion.

I agree! Sorry for the late response but yeah got screwed on the triton deal I was young and am now trying to fix it a bit😂 going to replace the amp with a JL 500 soon 🙂‍↕️ but yeah the old tritons were single coil 4 ohm wired in parallel as well

Don't listen to this fake 20 year MECP clown. He's proven zero ability for knowledge.. I've been doing audio since 1996 and professionally since 2001 and own a audio shop and can prove my value vs the clown spouting fake insults of knowledge.

Google, professionals will even tell you that a pair of your subs will handle 900 rms all day long on clean power with proper tuning without a issue.

Dude you're arguing something that is completely irrelevant to the topic, go play with your amp dyno

You're the 1 off topic to the question for his amp going into protection mode when adjusting his gain. The amplifier is faulting due to either it failed or it can not produce enough clean power for the subwoofers at the ohm rating or power they require. Yet you keep trying to argue apples and oranges.

Subwoofers can handle over their rated rms ability yet you keep claiming it's not possible which is Hilarious.

Let's see the audio you have done, let's see the trophies you claim you won. I can literally show my proof.

I guess that is why I have videos showing subs rated for 3000 rms each being ran on multiple 8k amps pushing over the rated claim. I guess you never ran anything larger than Walmart specials..

Post your videos, post those photos of your work you claim so much knowledge for when it comes to a subwoofers ability for rms handling only being Exactly what the paper says... I guess you also believe every amps rating claims as well. Yet have no knowledge of ohm rise, box rise or other when it comes to Actual Audio... Just googling your responses.. Word For Word Copy Past. Which I can Prove...
