a minimum of 800 to each or 800 to both, 800W rms to both is about right, since they are 400w rms subs...

U might want to look into that hifonics brutus bx1000d, it's a good amp, strong and has a lot of features for about $200...Can't beat that for the money, 700W rms is pretty close, 350W rms to each is no slouch, think about it.

Well, it is always better to have more power than you need. Underpowering will kill them and it will make the amp work harder so, a 1000 watt RMS amp would be perfect for them in my opinion.

Well ok...never heard of underpowering subs by 50W rms will kill them, but ok...And it's definitely not "always" good to have more power than what u need...But if u know for sure they can take more than their rms rating and be fine go with that... and who told u that underpowering a sub by 50W rms will make the amp work harder, that's ridiculous, the amp puts out what it outs out at a certain load, period...Not like the sub can physically draw more wattage from the amp cuz the rms sheet says it can take more...The hifonics will do 1000W rms @ 1-ohm but u would need the 80144As to get that load and u got 8014As so that's out, good luck.

Ummm, the MTX 8001 is a brand new model for this year that is CES rated to do about 850-900 watts RMS at 2 ohms at 12.5 volts. Thats why I said it would work out perfect for you.

Ravedarat,

Your right, it is the MXA 8001. I was thinking in regards to the thunder 8001. In regards to powering the 8104's with a rms of 400 and a max of 800watts, what is your opinion. More power than you need or less?

I routinly pumped 400watts RMS through each sub on a regualr basis when I sold them (They are clearence now) and never had a problem. They are power hungry and can handle quite a bit more than their rated 400 watts. I did one customers car using the DVC version and ran a 8100d to each one and those things just loved it so in my opinion, in you case more is better.

So, in your opinion, a MTX 1501D would be almost perfect for these subs, right? Wrong? If so, I think tht I will go with it.

cough cough cough... err, here we go again. NO, this is a myth, it is dead wrong. "Underpowering" will NOT, repeat NOT harm a speaker. Clipping, well now that is a different story and lower powered or cheaper amps are more prone to clipping in the hands of the inexperienced. But the amp will NOT "work harder" nor will low power "kill" the speaker. Impossible. It just won't be as loud as it would be with a larger amp.
