dc/dc converters

so i want to get the full potential out of my amps and i want to run a constant minimum 14.4 volts to them. where can i find these converters for my car? thanks

Why? Are you REALLY of the belief that it's going to make even 1dB of difference in an everyday driver? News Flash! It won't. Not to mention the fact that it would add an ADDITIONAL stage of loss, meaning you have to have even MORE alternator and battery to overcome THOSE losses. Waste of time, money, and energy, if such a device even exists, and I'm not sure they do. Search for yourself, here... Apparently, they do exist on CLOSE to the scale you need... Here's one to give you an idea... It's specs are: 12-42VDC @36A in, with 14-44VDC @33A out, regulated, (and the output voltage MUST be at least 2VDC higher than the input - so, even there, unless you attempt to run your amplifiers at 16.5VDC, so there will ALWAYS be at least 2VDC difference between the input and the output, you STILL won't get a regulated 14.4VDC. That high an input voltage will also cause your amps to run H-O-T, wasting even MORE energy...) at $835.00USD. If you think such an expenditure is worth it, you have some SERIOUS thrill issues, my friend. If you DO get one, how big an amp will 33A run, anyway? Well, let's do the math... 33*16.5= 544.5 watts available for input capacity 544.5 watts in * .8 (for a Class D amplifier) = 435 watts out. ANY Class D amplifier with more output power than about 400 watts will never run to it's full potential. It's around 300 watts (at BEST) for a Class A/B amp. Can you parallel them? Sure. Another $835.00, please! Each... Until you get the power you have to have, with about a 25% buffer for peaks! Figure six of them for a continuous 160A current capacity. 6 @ $835 = $5010! $5K to run about 2000 watts of amplifier. Bad trade off... THEN, you have to make sure you have the alternator and batteries to keep the DC-DCs powered! THEY will not be as forgiving as an amplifier if fed too low a voltage. An amp will just turn off... These'll fry. Forget this idea, man... Seriously, put it as far from your head as the idea that Nobama is going to save us... Google search for DC-DC convertors.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."
