What size amp?

I just got 2 kicker 10's (in a box) for christmas, and i have a 500w amp, but when i turn up my music, it kicks off and shuts the subs off, about what size amp would be good for the 2 10s?
i dont want to much amp that will blow my subs, but i want to run them without em shutting off when it goes louder. Can anyone help?

if there going off like that, your trying to get the amp to go up higher than it can so its going into safe mode. did you set the gains properly?

500 should be good with 2 tens. what are the specs for the kickers? RMS?

My bro said "150 RMS per speaker, 300 altogether."

oh then your gunna blow those speakers up. 500 is over powering them.
your gunna want a mono 300 watt amp or a two channel 300 watt amp that does 150 per channel.

so all you did was switch the subs? its possible the subs just cant handle the extra power. i dont know why it would be the amp since it worked with the 8's before so im guessing it would be what changed which is the new subs

So is there anyway i can just tweak the output power on the 500w amp? or would i have to go and buy a 300w amp? (which is my last resort) i can afford it, just dont want to unless its absolutely necessary.

this is a good example of my subs, not exact but close.- http://www.ebay.com/itm/KICKER-DUAL-...ht_3587wt_1270

im going to go by what i think it might bee but i need to know what amp you have to be certain

if the subs are 4 ohm and there wired together there gunna give you a 2 ohm load
and if your 500 watt amp is advertised 500watts for 4 ohms then its going to be close to 800 or 1000 watts in 2 ohms which is far too high for those subs and would cause damage to either amp or subs. the reason your 8's worked could be because they were wired in 4 ohms.

the best thing to do is to turn your gain on your amp all the way down and turn your volume up about 3/4 the way up and then just turn up your gain till you got it as loud as you will want to listen or when it starts sounding distorted which ever comes first... but essentially your gunna want an amp that puts out 300 watts in 2 ohms

Oh boy....You're not going to blow two Kicker 10's with 500w. You're amp is kicking off because more than likely, you have the gain set too high. Try setting the gain proper and you shouldn't have any troubles.

that amplifier is not a mono 500 watt amp. its a 4 channel and you cant wire it to one channel stable. its shutting off and going into safety mode. you need a 2 channel or mono channel amplifier. how do you have it wired?

and to set the gains preferrably you want a voltmeter. but if you dont have one you just turn all of your bass and treble settings to 0. all your eq settings to flat. turn off any loudness feature you may have. turn your gain on your amp all the way down and turn up your volume to about 3/4 way. go to your amp and start slowly to turn up the gain till you start hearing distortion then slightly back off. youll want to do this on a song with high quality or preferrably a 50hz sinewave tone
