Advice on an amp

captanham is right DEI owns directed/viper/orion/ppi.  good stout amps but i dont think the orions have the ballz they used too.  have you seen the new orion 5000 west coast chopper edition? big chromed out over hyped piece o'crap if you ask me.  we connected one to 2 dd9512s and actually metered lower than we did with my old school orion xtrpro 2400.  even though we had the xtr pro running 1 ohm, its only supposed to be stable to 2 ohms, but we all know better than that

anyway heres what i come up with for you @ 1 ohm around 2kw:

alphasonik pma 1200da-2470watts, pma 1000da-2060watts; audison vrx 1.500.2-2000watts; db drive platinum 2000-2000watts; digital audio dhc1604-2400w, dhc 1204-2000w; jbl bpx2200.1-1810w(cea rated); mmats d3000.1-2500w; niche audio na6000d-2400w; power bass r-xx 2000w; rockford t20001bd-2000w; soundstream ega 2000dx-2000w; swiss audio sdx 2000a-2000w; visonik v918xd-1800w, v2020t-2000w, xsite xad2k-2000w

if it were me id do a us amps 2000x-2000w at 4 ohm mono, .oo6%thd, dampening factor 2500

that list is just some amps that i had researched and made calls to the manf. on for competition and have in a data base.  i have not used most of those products.  wish i could afford to though!  output power i list is what the manf. publishes so alot of them may only happen if lightning strikes the amp, others may be kind of conservative to get around power rating rules in usaci.  goes back to 'you get what you pay for'

as far as testing amps goes, we use an o-scope on the amps in car, adjust gains till the wave barely starts to square at the top and then measure output voltage at that setting.  so output varies on the same amp by charging system in each car.  i recently ordered my own term lab meter so i can meter the spl in the car and see the wave as produced by the subs, not just the amp.  i think itll help because then we can jack the gains up on the amps till the subs 'clip',  that will take into account impedance spikes in the enclosure and we can get a more accurate output measurement.  the way we do measuring is very 'getto' but gives me rough estimate overall, and a very good estimate on amps ive tested in the same way.  even bought some amps last year before they went into full scale production and the manf. was calling us for info on real world output and impedance capabilities.

btw for your very own term lab meter goto
