eh, From my experiences with Earthquake subs, I would have to say that you can find better subs for a lower cost. (ie. retail cost on an Earthquake Magma 12 is $350.)
Now, as far as their amps...that 200DHC kicks... just make sure that your subs can take a lot of power... (oh..T7000's...ok)

Yep, I am using an Earthquake Amp 200DHC. And I will be getting another soon. I haven't had any bad luck with them. Just make sure that you can keep the voltage up. I benched mine at 1535W before cliping. Custom Car Audio on here had 6 of them in his van. I haven't heard anything bad from him either.
My friend's dad is the rep for earthquake. He just toasted 3 MAGMA 15's on one 200DHC last night. As with any BIG amp Respect the power....
By the way BIGMAN glad to see you got the Bronco running. Now you just need to get all those subs in there. My new subs should be hear Tuesday. Seems like my car is never done. I guess that is the point though....Nothing is ever good enough.

If he toasted 3 Magma 15's on 1500+ watts of power, he must have been clipping the amp and therefore distorting the output of the subs (until eventual meltdown). I was driving 2 Magma 12's with around 1300++ watts of power and always felt that they could have taken quite a bit more. However, I do have to agree that the 200DHC is a great little amp that puts out a lot of power. I remember when Car Audio tested the Magma 12, they couldn't get it to distort even when feeding it the maximum unclipped output of a Kicker ZR1000 (1200+ watts). I would love to see one of those 200DHC's on EACH Magma 15 (running 1.5 ohm mono). That would be giving them what they deserve. Hell, if he's a rep he ought be able to pull some strings and make it happen ; )

I've heard amps that clipped 'softly' when driven just past their limit, and I've heard amps driven into 'hard'clipping. I've also been told by very reliable sources that when you push a class D amp beyond it's limits, it WILL take out some subs. Clipping kills!

Yep, He clipped it hard. If you have enough power on hand. When you clip the 200DHC you will destroy your subs... It does clip very hard. As do most class D amps in my experience.

Lesson #1. Don't try to hook up 4 kicker competition 12's to a 200DHC... you are just asking for a smoky, smelly, ugly mess... (been there...done that)
and I agree...very HARD clipping.

You can destroy ANY sub with a small clipping signal... Try feeding a RF power DVC 12 square wave at 250 watts and see how long it lasts, if you don't like square wave try a 50% clipped signal... Most subs will melt in under 2-3 minutes, I have personally melted subs with 30% of their rated power in 40-50 seconds... I also plugged my 2 Pioneers into my wall outlet and they took the 4000+ watts of power with no problems... Try it and see for yourself, just make sure your box is built well...

The MTX RFL series subs I have heard come with a plug in, so you can plug them into a wall and they will not blow to prove to you that you cannot blow them. *he..he.. I wonder what my 3 phase power in my bay will do to it????

Talk about getting off the subject guys. lets get back to the question @ hand. As far as the Earthquake 200 dhc one of the most powerfull d-class I have tried also the most unreliable @ our store we Had a 100% failure rate that was about 10 out of 10 amps. even if they were @ 4 ohms with 4ga wire. Up like smoke they went. Earthquake also had the worst attitude when it came to warranty that I have seen in my 11 years of car audio retail. As for the mtx vs. jl question I just happen to sell them both JL pretty much beat the MTX in every catagory (sorry Loyd).
