Recently my sub hasn't been giving me the same output as usual. I figured it was because of the cold but the output never really changed once it warmed up. So idk whats wrong but basically its at half the volume it used to be.

I thought maybe I messed something up on the sub itself but the voice coil wasn't burnt, and there there was no mechanical noise. Basically everything looked fine. I checked the rcas and they were fine, so was all the other wiring. I redid everything on the amp just in case. The wiring on the sub was fine because I haven't touched it in months. Head unit setting are normal, nothing changed.

Any thoughts? Gain is also at 3/4. Never once played my sub loud when cold so i dont think thats it.

Amp is a Rockford T-1000bd and the sub is a Fi BL 15".

Have you had to disconnect you battery recently? Maybe you lose the setting on your head unit.

First thought is to measure the coils make sure one of the tinsel leads didn't become disconnected.

Also unplug rcas 1 at a time and see if they went bad. Just check over all ur wirings.

The settings on my head unit are fine. Its a very basic unit so theres not much i cans crew. Ipod's fine too.

I unplugged each one and they were good. Half the output each time i pulled one out.

I can measure the voltage tomorrow. They looked fine so i dont think its that. Im pretty sure its my amp but i dont know.
