i keep hear about people saying that they're 1 ohm stable, is this really true?
and how are people hooking up multiple subs to this amp with on the 2 speaker things, just the + -
sorry for bringing up an old topic, but i was going to wire my a1000db to 1 ohm and i dont want it to blow an amp im trying to sell later down the road...
they don't do rated power though that's the only bad thing.
Someone benched the PA A2400DB and hey said it benched 1250w RMS @ 1 ohm when the **** thing is rated 1800w RMS @ 1 ohm...others claim theirs benched1300w RMS but either way be careful setting your gains.
Also all I have seen the PA A1000DB's rated for is 600w RMS x 1 @ 4 ohms and 1000w RMS @ 2 ohms.
What's the max amp fuse rating on the PA A1000DB?The PA A2400DB has 4x 40 amp fuses on it so a max fuse rating of 160amps.
My look at it seeing as they have been benched at 1250-1300w RMS is like this...
160amps x 14.4v = 2304w PEAK/MAX
2304w MAX x .75 (75% amp efficiency) = 1728w MAX/PEAK
1728w MAX x .75 = 1296w RMS @ 1 ohm
1296w RMS x .75 = 972w RMS @ 2 ohms
972w RMS x .75 = 729w RMS @ 4 ohms
This is no way to calculate an amps RMS wattage though..there are two ways and unless you have the major boku bucks the second is your only option.
Get a DMM and a Clamp Meter.
But I wouldn't doubt that the formula would be a close bet with the DB series PA amplifiers.
