I am running 5 jl audio 8w1v2 single 4 ohm woofers for a total 0.8ohm load.
The electrical system is a 240a alternator, one stock battery and one 14ft run of 4ga ofc to a fused distribution block. The distribution block supplies a taramps smart 3 and a jl audio e6450.
Before running the smart 3 I had a RE audio usx65.1kv, then a US amps Merlin MD3D which is nearly identical to the RE amp.
The issue I have is the Taramps goes into low voltage protection (two flashes of the red led) when turned up but significantly below clipping.
Using the min/max function on a Fluke multimeter, the lowest voltage measured at the amp input terminals during a shutdown incident was 12.54 volts.
My question is: Is the smart 3 so smart the 0.8ohm load is shutting it down? Or will these amps shut down if the voltage briefly dips below 12v?(which could be happening and my meter may not be quick enough to see it.)
I have not been able to drive the smart 3 anywhere near the power level of the previous two amps. Neither of the previous two amps ever shut down or went into protect ever even after long periods of abuse.
This is the first time I’ve ever seen a taramps in person, therefore, have no experience with them until this week. Any input from those experienced with taramps is greatly appreciated!

Ran it at 1 ohm today and same issue. Seems to be more on punchy kick drum notes. So I don’t think it’s amp behavior, I’m leaning more towards an electrical issue. The ground wire is connected to a seat belt bolt, that’s going to be where I start.
Some seatbelt bolts have a sealer which can reduce the ability to pass current. Some have just a few spot-welds holding the threaded piece in place. That can also be a problem.
You might try using a 3/8" bolt and nut on a place where the metal is sanded to bare metal on both sides so both sides conduct well to the bolt/nut.
Have you upgraded the body to battery and the body to engine cables?
