Still thumps

I bought the same speaker from Sonic electronics back in 2012 i need one more. Earthquake speakers are well built and sound awesome It is still a great speaker after many years of thumping. And i expect this one to hold up as well. Thank's for the great service then and now.

Earthquake 15" tremor great value

I bought 2 of the earthquake tremor and put them in my Chrysler 300 and I wanted them to face the seats so when I pull the seats down all you see is earthquake symbol's and speaker pretty cool you can face 15's outwards towards the trunk easily but facing them towards the seats took a bit of modifying but my god I pull the seats down and crank it up you have to get out of the car it hits so hard and clear I can crank them up in my driveway and the bass huts so hard and deep I knock my pictures off the wall inside my house so do I recommend these speakers in my opinion you caint buy a better subwoofer that can do what these can do for the money hands down dollar for dollar these are the best sup woofers you can buy there are better subs out there but you'll pay 3 times the money these knock pictures off the wall inside my house let's be real sitting in the car it makes me nauseous if I crank it for to long what more can a Average Joe need.I won't buy anything but earthquake for now on I hope this review helps someone out if your debating on what subwoofer to buy when your on a budget this is the one hands down.
