Thanks man, for very good answer.

Yeah, thanks smartest guy on the world, yes I really need your answer as a blind man sight. No worries, I will buy one more extra battery, high output alternator, 50mm2 cables, but I think, that I will buy one another sub, this is DD Z95 15", because it can handle more than 4kW power daily, and is more loud than BTL or SMD. I'll wired it on 1 ohm. That is true, that is very expensive, but is one of the best. Yes and one informations, DD Z2-lv is low voltage technology amp, thaht mean that it work from 8.5-14.8V, and it has on 12V around 6kW rms. I think that is meaningless running that amp on 4 ohm. If I think run it on 4 ohm, I will buy cheap amp with 2kW on 4 ohms, and than run sub which can handle daily around 2kW...

I also thought about SMD, beacuse I want the maximum possible use amp power. Please sent to Drago mail with price, and how many will cost shipping to our country. Thanks man!

Yes I contact Drago, but I mean this for SMD woofer.

@ Duran this is this battery: http://shop.soundpressure.com/vpasp/shopexd.asp?id=95 @BILTD: I like do this, but I haven't enought space for 2 15", only for 1 15", but SMD is too too expensive for me, because I must pay more than 50% price of woofer for shipment. @ManRossDamn: I have big 3 and 0 gauge runs, and one battery (75Ah) in front, and one PC3000 in trunk. But I think thaht will be ok, if I turn my gain down.

Great. Yes, I have one additional battery for now (PC3000), but I add more if I will need more electrical power.

Hey everyone! I want to buy a new one 15" Fi BTL-N2 dual 2, fullly loadded daily version, but there is one problem. I don't know how many power woofer can handle daily. I have a amp with a lot of power and this is DD Z2lv this amp has around 8.5kW @ 1 ohm. Can this sub handle too much power? Yes, I know that I must turn gain down, but I buy this amp, because I think that better more power and than gained down than have amp with less power which clipped at maximum. I think to set my gain on amp to watch excursion. I want to know how is the durability at the maximum excursion? Can sub handle this? Please post your experiences at this power. Thanks!

It is called not knowing any better, and simply being a lemming and doing exactly what the manufacturer that really makes them says. It's simply not understanding how an amplifier works..in conjunction with a speaker. When you start to drop an amp below 1ohm more heat is being built up because the power supply and output portion of things of the amplifier simply cannot handle the demand that the output stage is wanting to get. When you do not have a subsonic filter...or one that is set improperly...you then start to make this thing that you've just microwaved move... You are slamming the gates open/closed on the output transistors at 90+% duty cycle, which is absolutely asinine and they freak out. Take a can of coke, pop the top open and bend it back and forth a few millimeters...within it's mechanical limitations that tab will never break. Now if you start to bend it past its mechanical limitations is when you start to get into trouble. This is where the subsonic filter comes in and making sure that you are not playing full power below port tuning frequency of a sub. If you already have something that's hot from running it hard on one of the Korean amps and you start yanking the soft parts past their mechanical limitations more and more heat builds up... You get to the point where so much heat builds up that the spiders start smoldering...they won't catch on fire until you've clipped the signal to death, vaporized all of the flame retardant spray that the spiders are soaked in and then it smokes. (square wave form, dc voltage out of the amp because the power supply cannot handle what you are doing to it) It's not the sub, there is absolutely nothing wrong with running those leads like they are. What's going on is an issue of the big cheap Korean amplifiers in and of themselves...and total ill-regard to what a microwave and conductive material does. Hope this helps you understand...if you run a Crown A6000Gti you'll never have a problem...because it's an A/B amp....the other stuff that is cheap...don't run it below 1ohm or you are going to have nothing but problems because in order to get that big power cheaply and cut out on the parts that are going into the amplifier the switching frequency of the power supply must be ramped way up...in turn microwaving woofer parts. Yes, that is true, I think, that little which amp can work on on .5 ohm, daily. I think if you have a daily sub in daily(big) box, you have a very big box impedance rise, which mean that if you want more efficiency from amp ( without clipping, buy sub with dual 1 ohm wire and wire down to .5 ohm, because in real life you got 2ohm impedance or more, thats the point of this quote. I don't know for woofer box without impedance rise.
