Nice subwoofer

Great sounding, true rms rated power 1000 watts easy I'm impressed

Good buy

Very pleased with my purchase. I bought this
Sub to replace the Polk sub I have. The earthquake
Woofer hits a lot harder and doesn't distort
when I crank it up. So far so good!

Deep bass and no distortion!

It's been years since I've had a subwoofer in my truck (previously owned fosgate p1's, kicker, polk audio, jl audio w1's). After a few days of researching - I've decided to try out the tremors.

I'm running this sub with an SSL 2000w amp and I couldn't be happier! Finished wiring everything hours ago and was testing the sub at high volume/levels (after tuning). I could not hear any distortion from the cone, which is key, since the sub is in my back seat.

No need to be skeptic on these subs - they will not disappoint! I would strongly recommend to anyone who doesn't want to spend a lot of money for quality or for anyone who's buying a sub for the first time; the tremors are the way to go!

Tremor x 12

I have owned a lot of drivers in my time, the sub is a little over rated, but not a bad over all woofer. Can't seem to destroy the damn thing.

Love them worth all the money.

I have owned p3's and seen power acoustic mofos. set up seen 1000 watt alpines but these are probably some of the best i have seen. i thought they were going to be smaller but when i opened the box i was amazed. the surround is a lot wider than i thought and the excursion is very nice. Even with 2 of these in my restricted space camaro they still pound. i have a monoblock soundstream running to them and i almost feel like 650 rms watts isnt enough for these subs.

WoW Really!?

I Recommend this to Everyone who is looking for some serious DB and SPL for under $200. I pulled this sub out of the box and I was skeptical and my friends laughed! Hooked it up and im under powering it mind you (ADVISE NOT TO DO) at 225 Watts RMS and it handles 625 RMS. All I can say is that the Engineer of this sub-woofer is a Genius. It is by FAR FAR FAR the best sounding subwoofer ive heard. At 225RMS this sub is hitting harder and stronger than subs Ive had over 500 watts on. So Happy with it im gonna get the right amp and get me a S.L.A.P.S. radiator. Awesome thanks Sonic for once again surprising the SH@$ out of me!

love them

Love them so soooo much!

WOW Super smooth and DEEP

I put Double the Soundstream RMS power to two of these 12's trying to test their limits. That didn't do it. They Just take whatever you throw at them and keep pounding! Better than my alpine type R 12's.

Best sound I have ever heard!!!

I had two rockford p1s being pushed by a old punch 800a2. I blew these and decide to try one of the tremor x124's. When i opened the box and saw the sub I was a little disappointed, but when i installed it i was in love. This thing pounds like crazy! I have it in a vented box and it is making both p1's look like punks. I am ordering 2 more as soon as possible.

Great subs

I just got these subs recently and they're amazing. Even underpowered on my Kicker ZX400.1 these things boom and hit every note I ask of them, which was my complaint about my previous pair of subs I owned. If you're looking for subs that can handle spl and sq, these are great. Great for the price, worth every penny.

Excellent!!!

Just got this sub an was very impressed. Have it hooked to a 500w amp in a sealed box, and the bass is very clean, and handles low frequencies extremely well. A+ in my book.

Insane

Giving x4 of these 2,500 rms, 5,000Peak and they are just smashing. So durable, they take everything you throw at them and they just laugh. Quality is superb.
I had x3 Kickers that do not even compare, the Earthquakes are in a whole different universe. I have run them for hours without them getting warm. The precision amp is nice as well. I love these subwoofers. I like that there Marine Compatible, No worries if you accidentally spill something on them. Honestly cant think of a Con. I got a con, they slam so hard they made me have to reinforce my box because the wood they where in was literally flexing 3 inches up and down. Looked like a trampoline. That was with a center post for support, i had to add 6 more supports. Simply ridiculous for such a cheap subwoofer.

Awesome

I had these in a box with the stuff you put in truck beds Armour or something, but with a Zeus 2 ch amp these would honestly make my hair stand up in a Pt Cruiser. The amp would get warm pretty quick n go into safe mode, but even not cranked all the way up these lil 12's hit harder than any other 12's I have owed by far, can't go wrong with earth quake speakers, idt they make these any more but I am certain the other's they make will deff rattle your head. God Bless!
