Can i use a 300 watt amp for 2, 800 watt woofers
yes, but you would not get the same performance as you would if you gave them the suggested power. I have found that it is always better to use a more powerful amp than your subs are rated for (as long as it is clean, high quality, low distortion power). I have had the best luck with name brand amps (kicker,rockford fosgate,phoenix gold,etc...). I hope this will be helpful to you.
A FRIEND OF MY GAVE ME A OLD PHOENIX GOLD QX180.2
I'm not familiar with that amp, but normally the power and ground terminals are larger than the rest. Are B- and B+ a lot bigger than the other terminals? It seems to me that power should be B+, Ground should be B- (although usually they are labled something like +12V and -12V or +12V and GND) and the R is probably for the remote wire (small blue wire that runs to head unit)
Lpf buttion on phoenix gold
LPF is typically Low Pass Frequency, it puts the amp in a state where only low frequency signals will pass thru to the speakers. LPL is for Low Pass Level control, that is used on PG products that have an LPL port. Using a phone style cable and a 50k potentiometer you can control the level of the amp's output.
Amp in protect mode
Check to see if the fuse is blown. If it's not, the amp is unfortunately fried. It would not be worth repairing the resistor in it
