Question about Car Audio & Video
U could just not have enough battery power or the load on the amp is to much. if the amp is in stereo mode it should work but if it is in bridge mode the ohms would be to low .. best thing is to get a sub amp with a 1 ohm stable capacity.. and you amp should be at least one third more powerful than the subs..eg: if the 2 subs is 1000 w each the the amp should be 2500 rms and up to prevent the amp from maxing out and over heating etc.

Ok.. Bridge the two sub into 4ohm than bridge to amp.
So. this how it goes.
sub1 + -
to | |
sub2 - +
amp (L) - + (R)- +
This will use the full potiental of RF 800a2 amp. I believe it like 1153 watts max out.

+ on amp output to + on speaker #1 to + on speaker #2. - on amp output to - on speaker #1 to - on speaker #2. This is a parallel circuit....4 ohms in parallel with 4 ohms = 2 ohms. IF it were wired in series....would represent 8 ohm load.

SOURCE: my nitro bmw 486 cuts out when i turn the volume up alittle bit,subs start crackling and distorting turn volume back down sounds just fine amp doesn't go to protect mode still works 4 guage wire a
The First thing I would check is, check the voltage at the power terminals of the amp. This to make sure that there is no problems with the supply voltage. If you have a fuse in the Red 4 gauge power line, check it before and after the fuse. The last place to check is where red 4 gauge wire connets to the main power supply.
Protection mode will also activate when the amp temperature gets too high. But since it is stated that the amp is anly warm to the touch. That should not be the problem.
I would check the speakers impedance if it is too low you might get same symptoms that you are experiencinng now. Also if the impedance is too high can
also cause this problem. Measure at the speaker with the speaker wiring disconnected from the speaker. Then take measurements at amp outputs. Also disconnect the wire from the amp and take the final and compaire the measurements, they all should be very close, I would say with in 1 or 2 Ohms.
Is it possible that the amp got wet, would you be willing to open the amp up to see if any IE( rain water had gotten on the board.
