subwoofers and amp

05spectraSX · Post by **05spectraSX** » Tue Mar 14, 2006 8:57 am

Hey i'm getting a 2 12'' subwoofers kicking out 1,100 watts. I'm going to get a 800watt wiring kit for everything. But what size amp should i have to power the subs. I want one that will power the best 1,100 watts but i don't want the ampage to be so much. Can i use a 800 watt amp to power them or anything less? The subs continuous power of 600 watts.

here they are: http://www.bestbuy.com/site/olspage.jsp?skuId=7044085&type=product&id=1099396976115

what are those "1100 watt" subs exactly? and the RMS of both of them TOGETHER is 600 watts? and what voice coil configuration are they? there are many factors that are needed to figure out what is best.

Dual Subs, should be run by Dual amps. That way when they die, they will die in relatively the same time. dude. you won't need another battery unless you plan on running your system at highlevels when your car isn't turned on.

seriously though, there are much better subs out there for the price, if you haven't bought them yet, do some research and look around. Also if you have bought them. Go ahead and buy the Dual amplifier too. They are matched to the output on the subs. It will pummle your brain dude.

joe is right... although sarcastic he is right... those subs are no good man... there are many better brands to spend your money on. save your money and buy something that will last and make you happy. instead of getting it and upgrading 2 months later. and u dont need an extra battery thats for sure u will be fine on your stock stuff

yes complete junk. If you want to go the best buy route. Go with only the type R's. Or the X's if they sell them there.

Subs don't put out watts, amps do.

1100 watts is a peak rating not RMS. As a rule of thumb, never pay attention to a peak rating. Look at the RMS rating, and match your subs and amps accordingly.

I wouldn't go over 600 watts if thats the rms rating. Especially if your talking about a low end brand like dual.

As they all have pointed out, you can do way better for the money. Check out the good, bad,and ugly in the FAQ section and it will lead you in the right direction.

if you're set on those dual subs, say the word, but here's my suggestion.

you're on a limited budget I assume, so instead of two dirt cheap subs (which will perform as such) consider one, better sub. you'll be just as loud or louder, and with better sound quality.

If you stick with those subs, they'll need about 1Kw between them, at a 2 ohm load combined, so you'll be looking for a class D mono amp that puts out 800-1200 watts x 1 @ 2 ohms. Expect to pay $200-350 for such an amp, and that amp will draw about 120A of current at peak output. continuous draw will probably be around 50-60A.
If you go with one better sub (say a 12" AA, EA, or RE sub) you'd be looking at about $100-250 for the sub, and $50 for a box built for the sub.. and you could drive that with an amp rated for 300 watts RMS and get great results with less power usage.

the secoond battery isn't going to help when the car is runing.
you'd need a larger alternator.
see the FAQ section on charging systems.

Heres my favorite saying:

A 100 watt speaker can be as loud as a 4000 watt speaker given thigns are the same

Power requirements by no means makes a sub loud, period. Anyone who tells you otherwise doesnt really know WHAT they are talking about.

Bottom line. You can buy all that cheaper stuff and end up investing more into it that you would be to take our advice, buy better quality lower powered stuff. Not only will it sound better, be louder and last longer- it will probably be cheaper or the same money.
