Earthquake any good?

I have been looking for a while, but haven't been able to get a definitive answer. It would seem that most people that their old amps were awesome, but their new stuff looks kinda cheap...Are they at least good performers? How's the SQ on the amps and/or subs? SPL? Reliability?

I've never had an Earthquake amp, so I can't comment on them, but I've owned a few of their subs over the years. Right now I have a pair of old school-ish 15" Magmas that're being used in my friend's Tahoe. It's been so long since I installed the subs, or even looked in the back of the Tahoe, that I can't even remember what kind of amps he has. I distinctly remember installing a pair of monoblocks. I'm thinking they're either MRP-M500's or ZX500.1's, but don't hold me to that.

I found the subs, in a beat to shit enclosure, at a local pawn shop. I gave the enclosure quite a bit of TLC and it turned out really clean looking. It's around 4 cubes sealed and the subs seem to like it. I had intentions of immediately loaning these to my friend, so I didn't spend very much time looking up specs. I'd really like to see what these things can do in a ported enclosure on more than rated power, but I really don't know if they're suited for that. Anyway, they sound clean, get loud and don't need very much power. If I had to complain about them, I'd say they're ugly. The ugliness is due to a full cone dustcap that makes the sub look like a flat piston. That's about all I can think of as far as criticism is concerned.

When/if they ever go down, they might just be my first custom built subs. I'd imagine the 3" coil and the baskets would be compatible with a lot of different soft parts. I'd buy them again in a heartbeat. If memory serves, I think they were around $100 with the enclosure. That's tough to beat for a pair of functional 15" subs that were built tough in the USA...

Although I am not a Zed fanboi, the Zed built Earthquake amplifiers were pretty solid. As for their subwoofers, I believe Earthquake used Credence as their build house back in the day.

I remember their older d2s and d3s back in 2002 usac finals,more reliable than their d5s or their red color amps of today.

Their pro audio mids are nice for the price. I want to say they are around $20-25 wholesale for the 6s.
