I'm getting the dayton audio 18" HO with the box bundle at PE. I am looking at different amps and would like to see what you guys can recommend. I've read the EUROPOWER EP4000 is ok.

What other amps are there that is budget friendly? I am planning on just 1 subwoofer.

Also, how do i properly wire up this sub? I wanted to make sure that i wire it right, but i'm not sure how to do it so that its X ohm stable etc.

That driver has a single 4ohm voice coil so any amp should power it without a problem. The ep4000 or inuke 3000dsp are good choices.

2 sub's are better than one!

No, the Dayton 18 HO has a single voice coil that is 4ohms.

You could run the EP4000 in bridged mode into a pair of Daytons in series for an 8 ohm load or run the EP in stereo with a single 4 ohm load per channel.
Going by Behringer's specs, the bridged EP into two 4 ohms drivers in series would have each driver pulling 875W.
In stereo mode, each 4 ohm driver would pull 950W.

So, pretty close either way.

Behringer doesn't rate the EP4000 for bridged operation into 2 ohms. :In case you were wondering:

Two would seem to be two too many to me too.

thanks oliver, i'm audio noobie, but, when you say stereo, are you referring to the second picture? When you say mono, are you saying the 1st picture but with each line split to 2 subs?

Yes. The lower diagram is stereo operation.
Bridged mono into two 4 ohm drivers in series would have the two drivers wired together by connecting the positive terminal on one driver to the negative terminal on the other. The remaining terminals would go to the amp.
IOW: Amp positive to driver-one positive, driver-one negative to driver-two positive, driver-two negative to amp negative.

Two would seem to be two too many to me too.

thanks. I would prob wire it stereo then to maximize the power.

Thanks!

For my setup, i noticed the EP4000 amp does not have a crossover frequency normally found on plate amps.

Would i just use my receiver to set the frequency then?

you'd want to get something like the minidsp that will have a high pass filter built into it. the receiver only takes care of the lpf

so i can't go receiver to amp to subwoofer? I would need a crossover unit like the minidsp? Which one would you recommend? Any low cost rack mountable ones?

I've been thinking about going this route with my next subwoofers. But I was under the impression that sealed subs do not need a HPF/subsonic filter? I know I asked Kevin from Exodus once about a sealed Shiva system and he did not recommend a HPF and that it should just roll off naturally, this of course depends on box size. I would think the 4 cu ft would be enough to limit excursion and provide gradual roll off.

Bass management (crossover) is done by the receiver. When an amp has a crossover knob, you want to set it at its highest and let the receiver handle it.

Correct.

You can still buy a minidsp or an amp with dsp so you can eq the bottom end of the frequency.

correct. but IF you have a ported sub you'll want the minidsp for the HPF ... if you have a sealed sub your'e g ood

another question, the power center i was planning on was the PD-915R, an 8 outlet 15amp power strip.

with the ep4000 at 4000 watts, is this going to blow the amp on the power center?

Other things plugged in will be pioneer receiver, PS3, Directv. in future, maybe some other stuff, but nothing high powered.

Most likely it will be fine for movies but if you start blasting away with music then it might trip the breaker.

My receiver is a 9.2 so i can run 2 sub lines. Does this diagram maximize the 2 subwoofers in both sound and performance?

thanks!

If your receiver can eq 2 sub's then yes, that is the best way to go.

if your AVR can EQ the 2 sub outs then go ahead and use them, if it only has 1 out you can either use a Y cable or set the EP4K to send the same signal to both channels. either works

well i must say after all the help, i got the subs running very smoothly.

These subs hit very hard, but more importantly very clean. I didn't push the subs to the max, but they are clean and hit very low. i tested the subs at different frequencies and even at 15hz, it was still moving and made some sound. I look forward to these subs adding a lot of LFE to my movies. One note is that with the EP4000, after the switches, having 2 subs instead of one for some reason makes a big difference.

Anyways, to anyone thinking about going DIY, this is really easy and i highly recommend it. The costs are not that much. I am lucky i dont need to finish the box as these are going into a cabinet.

once again, thanks for all the help!
