Get the dd-1 it is cheaper then replacing those dad subs. Also IMO just get the saz 1500 and go with what rms of the subs say.

Its OK to overpower them, they are built well and are rated conservatively. That being said, holy 2500. If you are asking the question the answer is no don't do it. Get the 1500 or like a 1200. I'm not talking down to you either, I don't think I have the know how to overpower them that much.

But yeah get a smaller amp and you will have money left over for a dd-1, win win. If you buy the dd-1 and end up not wanting to keep it, sell it.

The 2500 will be fine at one ohm assuming you have the proper sized enclosure and limited clipping. ( I wouldn't hesitate running half ohm on those subs with that amp, you just have to be very careful. Keep a keen nose and make sure nothing is getting hot etc)

If you just want to blast your music all the time and have no worries, you either need to get a 1500 or wire the 2500 to 2 ohms. Those subs are most likely capable of taking the full 2500 watts with an unclipped signal, but you are going to have to seriously pay attention. In my opinion your listening experience will turn from a good time into constantly listening and worrying about your subs. Just my opinion though.

good to know. thanks for the advice. i might just go to the bd-12 instead of the KMH, they are a bit more expensive, but can handle double the power.

So as an update,

It seems that everyone thinks I'm cheeping out on not getting the dd-1 for the $150. Im going to get it, its just 150 on top of of almost $2500 more because i have to get other things for the system too, new battery, alternator, amp, subs, wiring, head unit etc.... so i will buy it, i was just wondering if there was a cheaper way to adjust gains, but since it is so recommended that i but the dd-1 i will.

Secondly, i will either be downgrading the amp to a 1500, or upgrading the subs to the BD series so i don't blow the subs.

Thanks to everyone for the great advice :drink40:

The DD-1 is a must bc you can't set gains by ear, yes ppl have done it and got away with it. If the sundown amp comes with a clipping knob then go by that instead of the DD-1

I love my mine tho but that's your choice man. A lot of ppl use the clipping knob and have no issues

I like to have head room with the power I have on tap with my amplifiers, the Sundown 2500D is fine IMO.
