I suppose you guys will tell me I told you sooo when I blow an amp but for now its working great. Audioque is taking it well.

buy a bigger amp the liitle bit of added power of a 1200 watt amp at .5 ohms is not worth the current draw you will face a bigger amp at 1 ohm will most likly pull less current and give ya more power

So since DC is a build house and not a retailer its really odd for someone to knock on the office doors but last week thats what happened, The man on the other side said he drove 4 hours because of a woofer issue that the 2 different shops he had working on it could not figure out. They both had blamed the subwoofer for it not being able to handle 2000 watts. He explained to me he had spent a lot of money on our product and was really unhappy with it. its rms is at 2200 so he would expect it to take the 2000 watt amp he had it hooked up to. He explained he had purchased a DC XLm2 12 from a retailer and it was getting stinky quick and could not keep up with the rest of the system. He explained the system sounds great at low volume but there is a point on the volume knob that the bass stops getting louder but the rest of the system keeps going. I knew right then what was going on and said OK lets go take a look at it. His bass section of his system was a 4 volt headunit that feeds an EQ with high voltage outputs that then goes into a 2000 watt amp thats wired at 1 ohm. Should be an easy task for a XLm2 right. Just glancing at the settings It appeared it was probably all too high. I had just the tool to show him what was going on. I could have explained it to him but this guy didnt really know me so I could be some guy working at a shop just pointing the finger in a different direction. The better way is to get out the DD-1 and explain how it works, So thats what I did, I explained what a gain on an amp is for and how deck/eq voltage works. How over gaining an amp will cause an amp to run out of useable power before you run out of volume knob and how it will produce dirty power and how that effects the operating temp of the sub. He tells me he normally runs his deck at volume 22. So we hook up the DD-1 to the outputs of the headunit and its well within his clean useable volume clicks. What was good about doing this first is now he understands the way the DD-1 works, He was able to see how about 95% of the deck volume was all clean and how only the last couple clicks were dirty and lit it up. When we got to the outputs of the amp we were able to get to volume 12 when the distortion light came on, because he understood the way it works from the previous settings we went through, it clicked right away what the issue was for the guy. I think he was just relieved to understand car audio better and to also know exactly where the problem was, not just guess work and finger pointing. So basically we got a guy that rolls at volume 22 but gets dirty at 12. We adjusted his settings on the 2000 watt amp so that he could get the most clean power out of it at the volume he listins to. No more subwoofer heat issues and the sub now continues to get louder in a linear way with the rest of the system all the way up through the volume clicks, no more leveling off early and smelling. Huge thanks to steve, awesome job on the tool. from a manufacturers stand point, if that customer had not come out and got dialed in with the DD-1 he would just be a guy out there unhappy with his system, that includes being unhappy with us. But because we were able to tune his system and show him where the real issue was I think we have made a happy DC customer for life.

some amps double your ohms when strapping just cause some people do it and get LUCKY i stress lucky here they think they can do it all the time with any amp thats not the case i also know of a few that have ran there amps low blew them and replaced them before anybody knew and still to this day say they never had a problem lol cause fan boys can't have there brand look bad ya know! can't belive everything you see on youtube

Wiring at 1 ohm is for poosies. Wire at .25 or .125 for 4x or even 8x the powa draw. SO MUCH POWA!

amps never see their wired load alpine. never ever ever....................

Op you do realize that just because you cut your impedence in half you arent getting the same gain as you would going from 4 to 2 or 2 to 1 right? meaning you arent getting 600 at 2 ohm 1200 at 1 and then 1800 at .5 right?

did you even notice a differnce in sound? i would be surprized if you did

Lol why the hell would he use solo x's. I think he wants to use a sub that's not going to launch a cone when given rms power.

Full tilt I only drop to 14V while driving and my lights never dim. It might have something to do with my stock 155A alt, 1 run of +/- 1/0, and 2 spare batteries tho.

Here's how this works around here... I run .5 daily but will tell everyone else not to do it. Why? Because I, and everyone else who runs that knows there is a risk of blowing something and if it happens, we don't get pissed because we took a gamble and lost. But when someone else asks, we all say NO because there is a chance it can fail on you. We don't want to tell you to do something that can and will screw up you equipment. Here's my advice Do you want a reliable daily system? Yes - Wire to 1 and your amp will thank you No - Wire to .5, then enjoy the possibility of blowing the amp as well as a shit ton of draw on your electrical for not much gain Just remember... It wasn't all too long ago that wiring to 1 ohm was a new and scary thing

Don't do it.

Here come the suggestions best part

Doubled up the baffle for the 8 since it is much heavier then the othes .
