its just like sa Dc aa blah blah blah . all have their own stronghold and outragious price.i dont think DD is worth the money i know they make a killer product but danm
this is where i would disagree.
if i was doing a setup that needed the car off and i ran 14v batts. best believe DD is my ish. If i had a lil extra cash and wanted some good power for daily its my ish.

yeah what do i know. im only fooling with DD on a daily basis.
i cant afford to run hem and i love my mb 4 channels //content.invisioncic.com/y282845/emoticons/thumbsup.gif.3287b36ca96645a13a43aff531f37f02.gif. but everyone in the franklin county cruisers run them and i help install/tune/seqs with them. you really have no clue what you're talking about now.supposedly fools with DD on a daily basis HAS AN MB QUART AMP
This was exactly the type of answer I was looking for. Some of the stuff you said was familiar such as rail voltage, but for the most part it's all new to me.there are two different types of regulation in amp power supplies and one type in the amp itself-----in the power supply there is input regulation and output regulation-----and there is degree of regulaton----input regulation means that the supply is designed to operate over a certain range of supply voltage---for example 10 volts to 16 volts----this means that the amp should perform well no matter what the supply is----now the degree of regulation determines just how good the amp stays within spec throughout that range----some amps are very tightly regulated and some are not at all and loose power at the lower voltages---as far as input regulation i would opt for good regulation-------power supply output regulation refers to the ability of the amp to maintain its rail voltages at a fixed voltage as the amp is called on to change from no load to full load----this factor determines more than any other thing the dynamic ability of the amp----if the supply is tightly regulated the amp will have the same continuous power as peak transient power----if it is loosly regulated the amp will have the ability to produce undistorted musical peaks much higher than its continuous rating----- for this spec i would always choose the least regulation if the continuous power was the same between two amps-----the problem is most people don't know the difference between the two and seldom is it specified------there is a third kind of regulation-----this is output signal regulation and it indicates the ability of the amp to maintain a constant output regardless of load------this spec determines damping factor------as long as this spec is 30 or higher it is more than adequate.......
by the way---there are no totally unregulated amps in either of the three catagories if the amps have switching supplies (meaning over 50 watts per channel)--some amps are just more tightly regulated in some areas than others--- an unregulated amp would never work in a car at all
thats what he said idiot....DD makes power on 12v and makes a crap ton more on 14v......do u even read or u just quote people saying garbage
I'll chime in here.dd is under rated anyway from 12.8. so you may see an extre 5-600 and think its from voltage. im around alot of DD from the franklin county cruisers. i have some experience //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
/dd TF im calling youI'll chime in here.
DD rating their amps at lower voltage is good for two reasons. First, it helps with competiton ratings //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif And more importantly, it gives you a much better idea what you'll actually see on a 12v system.
It is true that DD's (well, at least the M3a) don't like much over 15v, they certainly make more power at higher voltage. they don't open up like some *coughD5cough*, but obviously they benefit as evidenced by my testeing last weekend.
DD M3a
- 3,657w @ 11.2v
- 4,088w @ 13v
400+ watts isn't earth shattering, but that is only a 1.8v difference. If you can hold 14v, you're looking at a 1k difference. And in the world of SPL, that 400w was worth .8 on the TermLab.
