Tremor-X154 (Pair)

By far the best subwoofers on the market that are budget friendly. If your considering on buying these i would not sit on them any longer. Just buy them you know you want to. Especially from Thunder AV. I ordered the dual voice coil 15s and was sent the single voice coil 15s by accident. Was brought to the sellers attention and within 24 hours i was reimbursed the difference.

I've been doing high end audio in cars, trucks, and boats for almost 30 years. Over the years there have been tons of new players in the game, but none can touch Earthquake. I have been a fan since the first day this brand showed up in my shop in 1995. No other brand comes close to the level of sound or bass these produce. Their beginning tier is even better than 95% of the competitions mid and high level. If you have doubts and want to spend 1000's that's your choice, but $ to DB's this brand is #1.

I'm old school so I've always liked earthquake brand you put these in a good box they sound nice deep bass

Subwoofer in my car died about a year ago but I hadn’t had the chance of looking for a replacement till now. After doing some research, I came across this brand and turns out earthquake has been making products for years now. This subwoofer is not one of their top of the lines but after installing it in my car, it actually sounds like a very expensive subwoofer. I am very impressed with the lows and how much bass it produces. I used to like Rockford fosgate products but I am now a fan of earthquake. Do not be hesitant to buy their products since they are not really advertised as other famous brands. Do not pay a lot for Chinese crappy brands, earthquake is also made in the USA.

Awesome sub! Just got to play with, but ended up very impressed! Hits them lows!

My trunk. LoL

Years ago, I was running 15 inch earthquake subwoofers in my car and transitioned them into the house because of their outstanding deep, tight bass. After years of service they needed cone replacement. I turned again to earthquake subwoofers and once again I have that superior tight bass for my home theater shaking the walls. The bass from these subs are deep and tight.

great sound and bass for the size of the box I have it in.

Pretty nice sounding budget sub the RMS rating for this sub is 450 Watts. If you go over regularly it will reduce the life of this sub. Pretty nice construction has vents for the coil to air cool it. Sounds pretty deep not much excursion but good for the price.

It works!

I paired this 15 inch sub to a 1500 watt boss monoblock amp and put it in a ported box. Outputs a lot of bass in my 98 grand prix coupe! Great sub for the price!

Boom

its awesome

Great high quality very stiff with huge excursion top teir sub

WOW!!!! For the price I honestly don't think that you can beat this subwoofer. The amount of bass this thing puts out is astounding, it shakes my whole car. If you are sitting in the backseat you feel like you are receiving a massage, and are lucky if you can see straight when you finally exit the car. It can handle quite a lot of power, and I can crank it as high as I can, without blowing my Bose speakers, and hear no distortion. I am currently running a Dual DA1000D 3000 Peak Watt Mono Channel Amplifier too it, and while it seems like it needs a bit more power to truly give the Sub the power it needs it sounds excellent. I'm talking get compliments on facebook from people in my town I'm not really friends with excellent. The guy who complimented me has two Rockford Fosgate p3 fifteens, and while overall his has more bass, this single sub gives them a run for their money. I am so happy I got this sub, and will definitely be sticking with Earthquake in the future. DBXI hear i come!!!! PS be ready to invest in some Dynamat, cause if your car has any rattles you will definitely hear them. It hits!!!

These subs are stupid loud! I'm not an expert installer but I know good audio and these are the best subs for the price. You can spend a lot more and get a lot less. Earthquake is the only sub I'll use. I’ve been using these things over a year now. They still slam! I’ve seen some low reviews and the main problem seems to be cheap under powered amps. These are power hungry, I have a 2500 watt earthquake amp going to two 10s and they take it all! Before buying your amp YouTube amp dyno test. Cheap amps don’t produce near the power they say.

I purchased 2 of these earthquakes in 15's and installed them in my grand prix with a 800 watt amp and makes my cars body flex like their no tomorrow....these are extremely loud and hit very very very low ....it is the best subs I have ever owned in my life ....you won't be disappointed

I got two of these in a ported box powered by a brutus 2000.1 super D and all i can say is DAMN!!! these things made my 4-12s sound like lil babies and i have the gain on half way...i love these subs they hit the spot!

Amazing bass high quality !!!

These are some great subs for a cheap price.

got two hooked to a 5000 watt amp (700rms) and they take the power like a champ and make my 12"s sound like babys great for the price and once again earthquake did not dissapoint

For what I thought I was getting, buy a sub and not paying a lot if $$ for. I was very very surprised when I hooked it up. It is very loud and hits very low and deep. I added it in with 2 12s in a slot ported box that I built. Placed the db meter in 3 different places and I was very surprised when I seen the reading. Played in between 130 to 142 db. I recently took it out before I got a ticket driving in town. Lol. Sound clarity is very clear and no distortion. For the $$ it is one hell of a deal when you get it tuned right.

I highly recommend these subs! I had two kicker comps tht I thought hit hard until I replaced them with two of these bad boys! I recommend a stronger back glass with these because they spider webed mine because they hit so hard! Other than tht, 5 stars all day! Well worth the money!

These bad boys blew away my fosgates earth quakes are top of the line hands down they are serious about sound

This sub is crazy in a ported box hit lows very well and it lives up to its name i just order one more let see what happen when i bring it down to 2 ohm i keep you posted and see what happen

Love the speaker, it works so good, has good sound, very good product, very happy with the product sound and product
