subs stopped working?

[Rainelli 10+ year member]

Ok I have an 01 buick lesabre. My headunit is a kenwood kdc-bt652u. And im running one fi bl 15 on a kicker zx1500 I've had issue after issue. I went threw 2 amps that were fried before I got em I think well I got the new one the other day installed it today and everything was great. Had some major flexing ( wish I would recorded it) but anyways I was tweaking the settings on the headunit and all the sudden no bass. Amps still on. Checked all the wires everything was the same as before. I switched all the settings back on the hu and still no change the last thing I messed with was the subwoofer phase I switched it to reverse for a split second then switched it back. But now I can't even find that setting. WTF please any suggestions will help.

check your RCA cables. And then your amp output. (both with a multi-meter set to AC voltage.) Your hu might have turned the sub output off for some reason.

What should they read on the multimeter?

Ok I tested the rca's they read .3 their was no output on the amp. How would I turn the subs back on? I unhooked the battery to re-set the hu and quadruple checked the settings im stuck

The only thing I havent tried because I ran out of daylight is checking the sub wires and the back of the headunit. But I don't believe its either

Some head units have subwoofer phase and on/off in that part of the menu. If you're lucky you just turned it off on the HU accidentally.

I checked and im pretty sure its still on.

Def sounds like u turned it off. I know sometimes the subwoofer phase will disappear when u turn the sub part off...

I checked it multiple times

I found the phase and the only options I had were normal and reverse
