mo' better bass: any substitute for watts?

more better bass is derived from a bigger power supply and transformer which translates into amps not watts. Current is what is needed to really move woofers.

Bob_reynolds has it right. depending on what the speaker impedence is at the bass frequency one is talking about, the speaker determines what wattage (power) is necessary to give the note at the required volume. If 100 watts are necessary into 2 ohms, then that will require so many amps, which will be more amps than if the impedence at that frequency were 8 ohms, but still 100 watts are required.
If the 100 watt amp is capable of delivering the amps at the lower impedence, then a more powerfull amp isn't going to be more capable of delivering more bass.
IOW, if the speaker can't do the job, then a more powerfull amp isn't going to compensate.

Let me try , I could be all wet here , it's been a very long time !

Volts X Amps = Watts , the basic electrical power formula if I remember correctly .
Now you can get 100 watts with 20 volts and 5 amps - 20v X 5a = 100w , high voltage watts .
And you can get 100 watts with 5 volts and 20 amps - 5v X 20a = 100w , high amperage watts .
Correct ?

Further , really going out on a limb here ... I believe that the differences in these two examples is achieved within the power supply , ie. the output transformer , and the way that it is constructed .
I believe that the transformers' size and configuration will govern how much amperage is produced with a given amount of voltage . It takes a larger/heavier transformer to make big amperage as opposed to a smaller/lighter transformer to make small amperage .
Isn't this the reason that a 5.1 A/V receiver , with its smaller transformers , can weigh in at 25lbs. and a 2 channel amp , with larger transformers , can weigh in at 50lbs. while both putting out 100 watts/channel ? The A/V receiver will give you anemic sound under a tough load whereas the 2ch. amp is capable of giving sound with much more drive and authority .
These transformer primary and secondary windings , and their proportions , are the reason that when you cross the speaker cables on that receiver you get a light show and probably trip a breaker or blow a fuse . Do it on a welder and you can melt metal together . Both driven by a 120v/20a circuit .

Now I understand that the speaker will require X number of watts to operate that tough load . But it is the configuration of those watts that determines how that tough load is handled .

Am I making any sense here ? Kindness counts !
