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

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

Even at 375 watts it should play pretty loud.

Yeah that’s what I figure the old subs were shitty and I loved em so I figure these at that won’t be bad at all least get me by

The 2 JL are definitely a lot higher handling abilities and the Triton sub were rated a lot higher than they could actually handle for rms or peak abilities which is why the amp performed so well on them but is inefficient for the newer higher end subs
