madmax3208 · 06-09-2005, 05:39 PM

what do u mean rating? im new at this

madmax3208 · 06-09-2005, 05:41 PM

i also have a one channel head unit so i think i can only get a monochannel amp

power handling, how many watts do they use? If I'm not mistaken, Those subs are around 300RMS and 1000-1200 max. You're going to want a big amp, match your wattage output numbers to your sub input numbers (300RMS sub = 300RMS Amp). You can use smaller amps, but you'll run into clipping problems at high power, I know, I ran 2 12" Infinity's with a 200W amp, what a waste of my subs.

ur right. how good are mtx amps? ive heard they are good but am not sure

PDC4runner · 06-09-2005, 05:47 PM

Subs and speakers are typicaly rated for how mutch power (wattage) they can handle they should have both an RMS rateing and a Peek rateing...

RMS prety mutch means average...
Peek.. means well.. peek...

soo.. if you have two subs rated at say... 150watts RMS .. you would want and amp that is rated to put out around 300watts RMS...

(anyone please call BS on me if im missin something..)

also.. my personal opinion when it comes to car audio... Ive found that typicaly you get what you pay for.....

hope this helps in some way...
im a little brain dead at the moment... stupid work deadlines...

if i have a one channel head unit do i have to get a 1 channel amp

What impedence are your speakers?
I believe most Infinity speakers are 4ohm, if you have two.. that amp work work. What's the model number of the speakers you have or are going to get?

Corollacrazy42 · 06-09-2005, 09:24 PM

you need a 2 ohm stable amp to accomidate the two infinities.. i was gonna buy them and still buying 2 10" infinitiy kappa perfects with an MTX Thunder 942 amp which should put about 470 watts to each.. the head unit doesnt have 1 channel, that would mean it would only be playing one speaker.. it has 4 channels and then aux outputs on the back to accomidate for other things such as amps and iPod connection.. knowing which kind of headunit you have would help greatly let us know.. oo btw that MTX is well strong enough to power your two and is about 285 at www.sounddomain.com right now.. check it out
