Review: Picky but worth it - I've got 2 of these running parallel showing my sundown audio 5k 1ohm the my amp draw is 350ish amps, at 13.5v so I am actually putting 5000 watts into 2 of these and I do it every day, 45 minutes at a time. Here's the thing. If your potted box is too big, if your port is to big. If you don't give this sub the proper back pressure in the box. Your going to cook it. I built each sub it's own box, exactly the size the pair that comes with the sub says, I used the larger option. I'm sure In a sealed box you can make it bigger. These subs are rated at 1250rms take my 2500 watts of pure punishment and have done it for 8 months so far, they hit 156 db in my 4runner but like I said if you over power then like I do, make sure you have sub sonic protection, I cross mine over at 50hz with a 18db slope. I'm all honestly I hardly ever turn then up to over 148db... I just can't see straight at the higher volume. The recommended box tunes these to 29 Hz . My steering wheel, peddles, wiper blades are bouncing around to much to drive. I've got 8" apocalypse getting 250watts for mid bass, and 200watts into 2 neo 6.5" midbass Dayton audio, and 200 watts 2 6.5" nvx separates and 50 watts into nvx 3.5" mid range. And honestly I need more mid range to keep up with the bass. Using a Dayton audio DSP unit and a taramps line driver to push 7volts into the RCA to the amps. My only wish is I had room for 2 more. When I cook these coils (and obviously I will at double the rms power) I'm just going to get the holees. I'm sold, earthquake for ever. Some tips to keep these running 1) subsonic filters 2) crossover at 50hz 3) Use the exact box size recommended 4) don't use crappy amps like skar, get a quality sundown audio, def bonce,down4sound amp. 5) boost your vehicle voltage to 13.5-15v and upgrade your alternator and add an extra battery and super caps. Don't clip your amp. Ever.. 6) see #5!! If your spending $600 on a sub spend that on a quality amp to protect your subs If your going to spend 600 on a amp, spend that on a power system upgrade in your car to protect that amp. If you can't afford the power upgrade, and the quality amp, don't buy these subs. Go but some boss and mtx so when you write a bad review you dont sound like the idiot that thought a cheap skar amp on a stock charging system would be ok, and blamed his mistakes on the speakers, not on the clipping that amp is notorious for killing subs and never hitting half the rated power even in a good power system.

## Questions & Answers

**Q: How many Ohms is this?**
A: 2 ohm and 8 ohm setup by a simple fuse movement. also can remove the fuses and run dual 4 ohm also with two separate amps

**Q: I have the boss 5k watt amp if I hook all of them up to it will I blow the speakers**
A: No, probably not. Boss is NOT a good brand. I had a Boss PH4000 (which Boss claims can put out 4k watts) that I was using to power a little 8 inch sub in a sealed box that was part of a DIY home audio setup I had. First off, I couldn't get more than 75 watts out of the thing (resistance was 3 ohms, input voltage was 14.4v). Second, it only lasted about a month before something inside of it caught on fire and filled my bedroom with awful smelling smoke, and I was only using it for a couple hours a day. In short, don't buy anything from Boss or any brands owned by Boss, such as Planet Audio.

Now, with that out of the way, let's talk about how to set the gain on an amplifier so that you don't blow your speakers. There is a common misconception that you shouldn't power a subwoofer/speaker with an amplifier that can put out more power than the speaker can handle. This is not true, as long as you set the gain properly. 

It's pretty easy to do. Start with the gain knob turned all the way to the left, set the music volume on your car's head unit to maximum, and play a low bass tone. 35 hz works pretty well in my experience. (If you're playing this off your phone, make sure you set the volume on the phone to max). 

Then, slowly increase the gain until you hear distortion. Decrease the gain until the distortion goes away. Congratulations, you're done. 

If you want your system to actually sound good, start playing music at maximum volume. Lower the gain on the amplifier until the music sounds good.

**Q: Also will my ssl evolution 3000w mono push this sub? its a 1 ohm stable amp**
A: the only way to get 1 ohm from these subs is to run 2 of them.

**Q: What size amp should i to push two of them**
A: If I was you I would pick up the scar RP 4500.1 it’s going to give you 4500 W RMS it’s a little over the max for two other subs but they will handle it just fine sorry it was supposed to say for two of those subs it will handle them just fine
