ampli; fake or original,sub underpower or not

[three in xe]

Good am mga expert,
Ask ko lang kung pano malalaman fake ung ibang amps aside from v12.Kc v12 madali lang halata naman looks pa lang if fake or not.In my case i have Alpine mvrf-1806 4 channel 5000watts color blue and my nkamold na black alpine logo sa upper leftside,siguro 5k watts peak e ilan kaya rms nito? 2ndhand lang kc ng binili ko.Eto pa,ang dnadrive nya is 1 solobaricl7 sims ok namn bumayo buo and malakas din di ko lang pnatatagal masyado kc nainit ung amps pag malakas ung volume pero kung tama lang at di ka namn nagpapaboom boom tlga di namn sya nainit.Sa tingin nyo kaya di match ung ampli ko sa sub ko?Fake kaya ung alpine ko?Pano po ba malalaman tlga kung under powered ung sub,ano nangyayari?Sorry dami ko na po tanong,worry lang tlga ko kasi baka mamya bigla na lang magusukan ung set up ko,sira na pala wag namn sana.Pls advice thanks a lot in advance.Have a nice day.

AFAIK, the most powerful v12 copy amp produces 85 W RMS per channel at 4-ohms. if i remember correctly, a solobaric l7 requires at least 700 W RMS. sooner or later, either your amp will give up or your sub will since pwersado na yung signal na ibibigay ng amp.
and yes, what you have is a bootleg amp. good enough for a low power budget setup but definitely not for an L7.

the cheapest, i think would have to be the us audio mono amp. can't remember the exact ratings but mataas siya for the price. 11,000 i think.
check out www.kotseaudioclub.com na lang. maraming makakasagot sa queries mo dun.

basta below ang RMS wattage ng amp sa sub, underpowered na yon. just look at their RMS ratings.

Axe..musta!
The best way to tell if a V12 amp is fake even if they sold an abundance of Orig V12 amps here..is the price. 1507 is around 3.5 more or less, 805 is about 3000 more or less. I think the orig V12 amps sell far far more than the fake ones. I remember seeing one for sale 8,000+.

Also there's a myth that, if you underpower your sub, you ruin your sub..which is false. Kasi, everytime you turn down your volume, you're underpowering your speakers diba.. so that myth should be busted heheh..myth busters. And just like enzo said, just look at the RMS ratings.

Pa audition nman jan haha. Ingat bro

amp. may orig na alpine v12s but there are also a lot of bootlegs. dude, search around the net for information about audio setups muna. most of the basic information you need can easily be found.
