Default Help!! Amp gets too hot!!

I have a sony xplod 1252gtr 800 watt amp
  • 2-channel car amplifier
  • 125 watts RMS x 2 at 4 ohms (170 watts RMS x 2 at 2 ohms)
  • 340 watts RMS x 1 at 4 ohms (4-ohm stable in bridged mode)
  • low- and high-pass filters (80 Hz, 12 dB/octave)
  • variable bass boost (0-10 dB at 40 Hz)
I hooked up a pair of 12inch kenwood KFC-W3013PS
Subwoofer Specifications I have the two subs bridged and i believe the settings are around 3to 4 db bass boost, and im not sure what the other dial is but i believe its set to 5v maybe a lil more or a lil less, today was my first major use of them and i had them running for about 20 30 minutes and the amp was burning hot when i checked it

Is this amp capable of handling the subs at all let alone bridging them or do i need a beefed up amp. Would a capacitor help me out at all cuz my lights do dim as well with the system running, any suggestion on how big a capacitor i might need?

your running it at @ around 2 ohms the amps is only stable at 4 ohms bridged of course its getting hot and your lights are dimmed..... you either need another amp one per sub or need to run it stereo one channel to each sub or run the subs in series if you do not it WILL blow the amp

il even do the math for ya

4ohm/2subs parallel = 2 ohms 4 ohms * 2 subs = 8 ohms
if you didn't already kill your amp
