Hello i am looking for your guys thoughts on 3 subwoofers.I live in canada and i picked these on ebay. The reason i decided on ebay is that some sellers use ebay international shipping program. Which is way cheaper then other methods . The companies that sell the very popular brands such as sundown soundqubed dc audio ampre ct audio legion and so on do not offer international shipping . Which is very expensive. So here are the 3 subs that i choose and hoping for info on .

Massive audio gtx 12 114.00 plus 32 shipping

American bass xfl 12 198.00 plus 70.82 shipping

American bass tnt 164 plus 36.00 shipping. This is in cad doller . Looking to get a pair . The amp will be a earthquake phd2 or hifonics brutus elite 2200.1. Some help on amp choice would be nice . They are already purchased

 
xfl is best outta those i do like way the tnt looks., i will throw out sundown SA bstock ($175) at car audio bargain but idk about shipping to u (cause i was about to ask if i should get that or FI alpha 12 myself)

 
do u have those amps? if not let us show u others.. the eq looks to be 600 max and idk about the hifi if it does rated power it maybe close the 1700 tested at 1199rms so maybe the 2k does 1500rms or so maybe..

 
The amps are purchased the numbers on the hifonics shpuld be 1700 true rms and around 2200rms dynamic. The earthquake have not seen any numbers . But used to be very popular. I tried cab for sundown for 2 sa sundown . The shipping was crazy. Gust wondering if anybody knows private shipping rates for two subs to ca

my 1st amp was EQ like 20 yrs ago 280 watt 2 channel.. rates to ca from where? man those massives i'm guess they be ok they are copies of like 8 other subs, probably be ok if u don't overpower them or under power them and clip amp or put them in to small ported box or tune it to high or use to small port., xfl even tnt lots better..

there is no amp dyno on the amps you listed bud. Use something other then hifonics or earthquake.

Got the hifonics specs from utube smd video. Same model but the 1700.1. It did 1200 true rms and little over rated on dynamic . So i guesstemated the 2200.1 would be about 500 rms less making it 1700true rms and over 2200 at dynamic . The eathquake phd2 has tons of info on internet. Most saying strong amp does 2000rms at 2ohms and loved buy spl competitors. Some say will go up in smoke. But i am thinking running it at 2ohms is safe . Kinda what i read

There's several other facts you need to consider about hifonics amps. They dont do any power at lower voltage at all. That 1700 amp did only 1199 at 14.95 volts at a normal charging system where you get normal drops down to high 12s to 13s, actual power output is closer to 1000 for that 1700. Not to mention hifonics amps has a horrible roll off after 28hz. Not just my own experience every hifonics amps swaps i've performed with other amps, have proved this with nothing changing other than the amp.

Those earthquake shredders were considered good at the time, they are extremely obsolete by today's standards along with the parts and internal components nearing the end of their lifespan after all these years.

Theres good reasons why I said those amps are poor choices. Name a budget and we'll find you a proper amp instead.

Budget is 400.00 usd . Was looking at synargy and twisted sounds on the ssa store. Any other opinions would be nice

those two brands are MILES AND MILES better than what you were looking at. ZERO comparison. a synergy wfo 15.1 and TS1.8KW are WAY better choices then the other two junk amps. Quality built underrated Korean amps vs overrated cheap chinese and outdated dinosaurs.

 
This is a bit hard to follow, but does OP already own the two amps? I wouldn't buy either unless it was a really crazy deal. IIRC the old Earthquake was only 2 ohm stable so you really pigeonhole yourself for amp choices down the road when it fails from old age.

Also I believe Incriminator distributes in Canada, any of their products should be good quality and perform as advertized. If you're only looking to run 1200-1500W consider running 1 higher end woofer of a larger size over 2 smaller lower quality ones.
