well i bought the L5s today. They came in a duel chambered sealed box. There not 4ohm like i was told, rather 2 ohm. Meaning i can only wire them down to 2 ohm. So no i gotts find an amp that does 1200 @ 2 ohm, or sell 1 and wire 1 down to 1 ohm.
A great option that Id personally definitely 110% choose if I were you would be to use 2 of the brand new Sound digital SD400.1s. Rated at 400rms @ 1 ohm but are far more efficient than other 400 watt amps out there so you will get more power. Their 12000 watt amps are putting out 19 000 watts in my friends setup and their 8000 watt amps are doing over 14 000 watts in many other setups around the world. These amps are absolutely amazing fully innovative power that comes in a super small package. This SD400.1 is absolutely tiny! When I say tiny...I mean THIS TINY!
Amp dimensions are only 5 1/4" X 6 7/8" X 2 1/16" tall. One of these per woofer running at 1 ohm and you would be absolutely set! Also to make it even simpler these little bahemoth amps are strappable. Which used to be only reserved for high wattage SPL amps but now the better companies such as SD who listen to their customers are making every amp strappable that they can. So with the amps strapped they function together as one amp making things a bit easier. And another thing to top it off...this are class D FULL RANGE amplifiers. If you wanted to later on run say 8 sets of component speakers in ur doors these two little monsters would do it and sound great doing it. NOT TO MENTION A 5 YEAR WARRANTY. These things are only $199usd shipped each. Id highly highly recommend them. I know the north american rep quite well through talking with him online since last summer and he knows his stuff!! Plus if you later wanted to sell one woofer you could offer them a combo deal with an amp which people are always looking for due to their lazyness.
Or you can always find an amp that will run 0.5 ohm daily. Look for a sundown 1500D used...should be able to find one for cheap.
Most good 1000 watt or 1200 watt rms @ 1 ohm amps will play daily at 0.5 ohm if you keep em cool but more importantly if your enclosure is designed based around the idea that the amp is playing on the verge of going into protection.
Look into amps from orion (older all silver 1200D play 0.5 ohm daily), memphis, sundown (1500d), hifonics, autotek, stetsom (1k6d-2ohm), cactus sounds, digital designs, soundstream, american bass.
But I do highly recommend the sound digital amps theyre quite amazing. I assure you they are no scam no BS numbers no trick pictures. All of their amps are remarkably small due to the technology they use being completely different power wise than other amps on the market.
If you're interested in the sounddigital amp please PM me and Ill send you in the right direction. (im not a dealer of SD if it looks like im pushing their product as if I am)
