ok so i got this all figured out. so my subs are 800 rms at 4 ohms and im going to wire parallel. so i found an amp that powers 900 rms at 2 ohms. will this over power it if each sub has an extra 50 watt? the peak of the amp is 200 watt below peak of my subs tho

 

If you have 2 subs rated at 800Wrms each; you want an amp that puts out 1600WRMS at 2ohms.

 

ops yeah i meant 400 rms at 4 ohms each. So i was searching and if i turn down the gain a bit they should be good to go and i wont blow them?

 

An extra 50Wrms per sub will not hurt anything. You will not see the full power to the subs anyways unless you are running your system at 100% volume all the time which is highly unlikely.

 

i have a 400rms sub running off a 700 rms amp.....wrks great no issues.

just dont crank up the gain on teh amp or blast the music too lound, but ya 50 more per sub not a problem
