Sorry I took so long, been really busy.
The woofer is a 12" P312D2 Dual 2 Ohm 500 watt RMS 1000 watt max
the amp is a 340 watt Dual XiA2346 2/1 Channel Amp
My current setting is I am using it bridged on one coil.
I bought this sub pretty new off of craigslist because my old 12 for some reason blew and won't play over 15 volume, because the amp would go into protect.
My friend tuned this amp by ear because none of us have O-Scopes but I switched the Crossover from Full to LPF, so now it just plays bass instead of music. I have no idea what the Input level or Crossover Frequency is on. But the input level goes from 6V to 200mV and the Crossover Frequency goes from 40Hz to 400Hz
Right now, if I have the SUB setting on my headunit set to 7-10, if I turn my volume over 18, my sub wont play when bass hits(the amp goes into protect). I don't know if it is a problem with my amp, but sometimes my car doesnt start..like it is totally dead until you touch the negative terminal on my battery, then it starts up. I think it needs cleaning, that might solve it.
But yeah, those are the specs.
I hope you can help on how to set it up.
