if you upgrade the big 3 you should be fine with a stock alt. on that little bit of power

a/b are less effecient, will draw more power, will it not.....at least thats what I was lead to believe.

class D is a mono sub amp, built specifically for driving subs

well I would like to suggest a sundown, but its a little hard to find one used, and their a little pricey.

what subs and voice coil config.?

but really with that crunch I bet you would only get around 500 watts, if your lucky. then the gain/bass boost would get maxed out to compensate for that and it wouldnt sound too great......

but cheap power hifonics is the way to go. this amp has been suggested a million times....but oh well, its a good deal.

^^^its power, not the best quality, but it will definatly kick the crunch.

^^ tested at .35 ohms over 2200rms on an 85 amp alt(dual batts)

that term is used as a scam to make a buyer think he is getting that much power. along with "max" or "peak"

you want to look for the "rms" wattage, which means continuous power.

some companies rate their amps at different voltages also.
the higher the voltage the more power it will produce.

for example the hifonics is probably rated at 14.4 volts which is as high as most charging systems charge to. BUT as soon as you add a load to the charging system the voltage will drop, resulting in a decrease in amplifier output.

while the sundown is rated at 12.8 volts(1500watts rms@12.8 volts)

then when you start your engine the charging system bumps up to 14.4(idealy) so then the power from the amp exceeds the rated output.

hmmm makes sense now.
yeah i know what RMS is. thats what i always look for
i love going to CC or Best Buy and they try and trick you into thinking that.
i've helped a few people from getting ripped off

youre a bit off bud. there are plenty of full range class D amps available on the market. Just to name a couple... alpine PDX and eclipse XA. Class D is not only for subs.

well to be technical, a sub is a speaker. But yes, they are full range class D. Meaning they play the full range of frequencies just like a full range class a/b. That is what they are designed to do.

how come onlinecarstereo lists the pdx's frequency range from 20-200hz?

thats considered full range?

shouldnt a full range go up to like 20 some thousand hz.

im confused....

Class D circuitry is for the most part the most efficient circuitry. But it does yield higher distortion levels...

which amp specifically are you looking at? if its their 1.1000 well ofcourse its going to say that. That is their sub amp. the 4.150, 4.100, and 2.150 amps should all say 20-20,000hz. If they dont, then that site is wrong. go to www.alpine-usa.com for the real specs.

the new icepower class D circuitry noes not yield the normal distortion of a regular class D mono amp.

gotcha, I thought you were saying that the 1000.1 was full range.
