good combo? 2 15mags and 2 massive audio p1000.1 amps...i was told the p3000.1 or the 1000.1 but the 3000.1 is huge and would take up too much space and also cost $50 more.

or is their a better combo amp/sub to run besides these subs?

thanks!

the IA 20.1 is "out of stock for a while"

look into the Sundown Audio SAZ 1500D

I have heard it and thought it was putting out more power.

If you want to use the P1000.1 amplifier I have two amps identical internally to the P1500.1 for sale, check the for sale section. Only $270 shipped for the pair of them.

I will tell you this, while it is not a bad amplifier that line has questionable stability at 1 ohm under stress. They won't complete a 1 ohm resistive power test, as per test done by K&B Audio on my identically built models - the protection circuit kicks on. I DID use one on a 12" SI Mag at 1 ohm with no issues, but I am not one to really abuse a sub/amp combo so this does not mean YOU won't run into problems.

The P1000.1 will also be far from capable of pushing your Mag 15s to their potential, as the P1500.1 is more realistically a 1000 watt RMS amp at a reasonable THD level... thus the P1000.1 is probably more likely 750 watts RMS or so with reasonable THD.

As for my SAZ-1500D... it was tested by Nick Morgan at 13.8 volts in-car to produce 1550 watts on a 1.9 ohm reactive load -- real world power. It is underrated and overbuilt. You will get what you pay for and more. Cutting corners now is asking to change your setup later when you decide you aren't happy with it.

where are the test of the P1000.1 and p1500.1? i never had a problem with them and they where strong, and cleaner than alot of other monoblocks. to name a few the memphis 1000D and RF BD 1000 and lanzar opti 1000D(decent amp for the money). I have had nothing but good luck with massive.

how much is your new 1500?

I got it covered. I think the SAZ-1500d would be a great choice. Now that I know it can handle .5 ohms and I suggesting to every mag customer I get

I erased my for sale thread as there was no real interest, but the results are as follows on the "P1500.1 equivalent" test:

Tested by K&B Audio.

12.5V 4 Ohm: 388W @ 3% THD, 38A

14.4V 4 Ohm 520W @ 3% THD, 43A

12.5V 2 Ohm: 732W @ 3% THD, 64A

14.4V 2 Ohm 810W @ 3% THD, 75A

At 3 times the rated THD it does not meet rated power. It did not pass a 1 ohm resistive test, and in fact, blew out a rectifier diode during the test. I replaced all the rectifier diodes in that amp since I have it up for sale and I wanted to make sure none of the other diodes had problems.

It's really not a bad amp overall... since I was able to run a 1 ohm nominal load on it in my car on a Mag 12. It is simply overrated and not overbuilt enough for my tastes -- IMHO, any amp rated to handle 1 ohm should handle that resistively.

As for my product, the SAZ-1500D, I am having an intro sale until the 28th at $450 shipped to the continental 48 on my forum here on SS Audio. Go there for more information as this is the SI forum so I don't want to post all about my equipment here. After the sale, Low-Hz will be one of the few net' dealers to pick them up from.

Im suprised that the amps didn't do rated power. never had a single problem. the 1500 does 1250@ 12 and 1500 @ 14.4 the 1500 goes for 380 compared to 450. its a great amp IMO and for the price its a good deal. there output is clean. some amps do 1500 with 45 volts and 45amps. others do 65 volts and 31 volts. the high voltage amp will introduce less strain on the inductor.

good to see someone else with amps out but i don't think i would spend 500+ on 1500 when i can get 2400 for the same price(atomic 2200.1).

im interested to see what amprage.volts you get on the output teminals.

75 amps for 810 watts isn't bad at all. would expect to get about 1200-1300 clean watts @1ohm. its about 75% efficient which is good.

Their P1500.1 is rated 1250 @ 12 volts... it doesn't DO that, at least not anywhere remotely near rated THD. Just a small correction. I will also disagree on clean -- triple rated THD for less than rated power isn't clean by my definition. Not that it sounds terrible, because it doesn't, but I wouldn't go so far as to call it clean either.

Comparing the P1500.1 to the SAZ-1500D is a misnomer. They aren't in the same class at all and cannot be compared. Of course the P1500.1 costs less to the consumer, as it costs less than half as much to build! I have the price sheets from the factory Massive uses, so I know this for certain. For that matter... the P3000.1 costs less to build than the SAZ-1500D does. Does that tell you anything about the comparative quality?

As for the comparison to the Atomic, I can't comment as I don't know anything about the amp. Is your price authorized with warranty?

honestly its not fair to compare the atomic to the 1500 as it get them directly from george, but i will definitally keep you in mind. i also understand how expensive it is to do something of this caliber and i respect you for doing so.

As for the massive amps i have had good resluts with them(3% THD is barely audible if at all in woofers. I do agree there not the cleanest but they are good amps. i realy like the comp stuff which is probably much more comparable to your product.

3 years ago, I ordered 4 amplifers from Atomic, they ended up in Africa, I ended up not running Atomic

From what I have heard, very nice equitment...go for it and let us know how you like umm!
