Question about the dual 15" L7 Kicker Subwoofers
It is recommended on the Kicker Website that the Dual L7 Sub-woofers should be powered by a Kicker ZX2500.1 Amplifier... Here's what I do not understand as I'm new to the "technical terms" Of car audio
L7 15" Sub-woofer is Rated at 2000/1000 Peak/RMS respectively
the ZX2500.1 is a Class D mono-block 2500 RMS amp at 2 Ohms
Now I'm no mathematician but the subs are 1000+1000 RMS = 2000 RMS.. the amp is 2500 RMS.. (Also all kicker amps are under rated so its more like 2701 RMS.)
Now here is my Question.. Wouldn't it blow the sub-woofers running off that amp?
No. This is called 'headroom'. You can not have an amplifier that is too powerful, you will just have a lot of headroom. Provided the gains are set accordingly, everything will be fine. You could potentially run a 150wrms sub on a 1500wrms amp and its fine. I used run 250wrms through my front splits with almost zero gain, and its fine.
When you have headroom, the amplifier does not have to work as hard to power the speakers / subs. So its a good thing

Also Kicker don't have a 2000wrms amp, so they went the next size up. Did you think they would recommend a competitors amp

I didnt say they have a 2000 RMS amp, I said they have a 2500 RMS amp

Read the post again he said Kicker don't have one so they suggest the one closest that they have which is 2500W
Welcome to the internet where people have opinions that you might not like
So I should be right with the 2500 rms on the 2 15" L7's?

Will be fine mate. Always good to have a bit of head room. Can't think of any thing else that would suit that would be lower priced. You could contact the audio seller Joe Bellisimo before you commit though? He's a site sponsor I believe and might give you some options.

I want a full kicker system... If I waited like 2 monthes I could get 6 18" Solo X subs with 2 Kicker warhorse amps, But that might be a bit much

Oh well in that case sure it will work fine and you know you won't even be stressing the amp

Thanks so much for the help :P now what car to put them in
and two 1000watt rms 15" subs isnt????
Well, the 18's are 3000 RMS each.. So Yea this isnt that much compared to that
please... do it. Get the 6 18s with the two warhorse amp. How in gods name do you intend to fit 6 18s into a VS?!

your question at the start seems a bit silly if you intend in getting a big system, come on you should know this stuff

Don't get too excited about 'Kicker amps being over rated'. I thought they would be under if anything...
Your rating for the amp is 2ohms, Depends on which subs you are choosing too. As they make 2 and 4 ohm options don't they ?
Ill be doing the 2 ohms and im getting another car obviously haha
