He forgot Zapco... But I have one question for you... Why? Even if it is capable of running with a half ohm load, the heat output is higher, the distortion is higher, the damping factor is lower, the efficiency is lower... All the bad things about amplifiers, just magnified... Why not get an amp rated at the desired power at 4 or at worst, 2 ohms? Your cost per watt will likely be lower, and the amp will run cooler and more efficiently. If you are looking to compete in something along the lines of SPL ONLY, in a 50 watt class, but you want 1000 watts worth of output, then go for it, but if you want ANY kind of sound quality, you are going at it the wrong way..

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Everything thanks for all of the help. Haemphyst to answer your question yes, it is for a friend that wants to do SPL. It is his daily driver so I will also have some relay's on it so that when the switches that control the relays are off the two subwoofers (in this case two Audiobahn 12" Pro Compressions) will be running in stereo and will be wired in series. Since it's his daily driver and he has a young child he wants this option so that he can still drive around with some moderately good sound and at the same time not make his child deaf. When both the switches are put on the subwoofers will be running mono and wired in parallel. These subwoofers are 1200 watts each rms and have dual 2 ohm voice coils. If you have any other ideas that might fit my friends bill then please put it on the board and let me know. Thanks.

US Amps is the best for a competition SPL amp, or MMATS. They'll build you a custom amp for your needs. If anyone can do it, they can! Some US Amps go down to .25 ohms!

800D will probally serve your needs i used one at 1 ohms and really stressed it running high watt subs. The alpine used to run the door speakers(250RMS each) heat up and would shut down. There highly efficent so thats why i recomend that series.

i highly do NOT recommend alphasonik amplifiers for 1 ohm or below, i actually don't recommend them at all because they are made by the evil lord audiobahn... stick the companies i mentioned above.

Do explain why you don't recomend it? It pushes the power very efficently and has an ausome warranty. Yes it was bought by audiobahn but its been around since 75. I have done alot of systems with these amps, and since then my customers refuse to buy any other amp, you just talking about shhh you have no idea about.

I'm not talking about "shhh" i don't know about, since i have been installing for 29 years. Alphasonik was a great brand in its former day when it was real equipment, much like the older PPI stuff. What happened to them from Audiobahn is what happened to PPI by Directed. They were bought out and the products changed dramatically for the worse. Ever since, neither product has been good.

They are not efficient compared to those i listed and you need there warranty because they break. Get a real amp like the ones i mentioned above and you will see the difference, hear the difference, and feel the difference.

Anything owned by Audiobahn is NOT a great product...

Lol this just makes you look on fools cause you are not looking at the product just a supid byass. Call it all ya want but i got customers loving it, and it was in my car till i sold it. So say all ya want. I'll put it up against especally the stuff in you car Dwarren.

How are you going to prove anything if all you know is your customers love it. Where is your proof. Customers can be sold and love anything.

You need not take this so personally, but rather more objesctively. It is well known that products from audiobahn or the likes have questionable integrity. It was suggested by those who have bad experineces with them that there are better options. Uthink is very opionated but has made his point none the less.

And by all means put any thing up against my system. I haven't any doubts about any of it. Escpecially the isntall, as this can make or break equipment.
