Printer Friendly Forum Posts - thoughts on the kicker kx1200.1

Specs:
300 watts RMS x 1 at 4 ohms
600 watts RMS x 1 at 2 ohms
1200 watts RMS x 1 at 1 ohm

Thinking about running TWO 4ohm S10L7's @ 1 ohm in parallel...

Anyone out there have anything to say good and/or bad about the amp?

All opinions are welcome.

Thanks in advanced!

I have been using that amp for about 3 years now and love it. I was originally running it at 1 ohm on 2 kicker 12" L7's and never had a problem at 1 ohm for the year and a half it was running that way. I have it wired at 2 ohms now on just one of the subs and it is awesome.

very good amp no problems here

How exactly is that working out for you? The S12L7 sub calls for 750 watts RMS @ 2ohms and the amp puts out only 600 watts RMS @ 2 ohms...

Sounds like to me you are under powering the sub..

Even with TWO S12L7 subs that would call for 1500 watts RMS and the amp only puts out 1200 watts RMS and you would have to be running the subs in parallel to achieve that, not to mention they would both have to be 4 ohm DVS subs...

Under powered...still....

well as far as underpowering yes just a little....

have had this setup for almost 3 years and no troubles what so ever...

Lucky...Known people with lesser under power issues and they had worser problems...

Your setup sound better than a couple S10L7s? Ever heard the difference?

-------------

well only comparison i have is a H3 to a Wrx with 2 tens

the tens sound great... an so do the 12s

Also have gone with a 10" sub. I found 12" subs were always not as a tight as hit than compared to a 10 in a sealed box...

Guess it is all personal preference...really curious about the S12L7/L5

-------------

well as far as being tight.... the 12s keep up very well in my opinion..

a local guy here in town is a drummer and he liked how well the 12s reproduced the kick petal or what ever that is hahaha cause his system thats what he goes for more than the vocal end of things...

the song was i think something like tool or some crazy fast drummer

also the guy with the tens listens to all types ( i mean all types) of music and he loves his 10s in a sealed box

the 12s are in a ported box

honestly since the type-r's have come out 12s really give some tens a run for there money when it comes to tight bass... what u think ?

I think 90% of "what sounds good" comes from the actual enthusiast. It all depends on what "YOU" like. I would like to go to the S12L7s but I already have a dual 10" sealed kicker enclosure...maybe find a really good deal on some 12's in a box and I might consider...

I think it would be a good change...especially because I have had practically ALL the different brands of 10s...

Nice...

and true...depends upon the listener

Some people have the gift...others don't ;-)

Some people think a pyramid amp & sub are the greatest thing around...then they hear a real system and are blown out of the water...

=P

It's working out great on both accounts the amplifier actually came with a birth sheet of 1547 watts and I am running a red top with the big three done and a 275 amp alt so most of the time I am running close to 14.4 which makes this amp spot on.

Could you post and/or email me the birth certificate? I want to see it. A decent scanner can do the job! Much appreciated.

There is nothing wrong with underpowering speakers. You won't even hear the difference between 1200 watts and 1500 watts.

The speaker does not "call" for 750 watts...that is just a rated continuous power handling.

No unfortunately I don't have the birth certificate anymore I got rid of it when I moved and I agree with Azn you wouldn't be able to tell the difference anyway, it would be under 1dB of total gain if my maths are correct.

Sweet sounds real good. Only if I already had a dual 12" box...I would some 12s..

If you won't hear the difference than what is the point? And obviously there is going to be some difference between 1200w and 1500w...300watts!

I know some hard core audio enthusiasts that can and will beg to differ about that statement...

For every 3dB (which to most people is an inaudible difference) you need to double the power so to go from 1200 to 1500 watts you add less than 1dB which I stated earlier, if 3dB is inaudible well you get the point. so realistically there is no audible difference between the 1200 and the 1500.

So what is the point of having a Kicker KX1500.1 if you just could get by with the Kicker KX1200.1...better yet why do the manufacturers of these companies still make the amps if there really is no difference besides the "huge" price gap...

I agree with what you are saying, no worries :D

It is an amp...what does it matter?? Kicker makes money
