there is a ton of stuff better than kicker. what are you looking for and how much you looking to spend?
X2^^^ but in response to your pm.....if you are looking for a kicker L5 or L7 then i would say a Kicker SX650.1 (if you want to stick with kicker) if you are open to other brands then post your budget and what you are trying to accomplish with your system.

Trying to accomplish a good sounding inside and outside system that would fit in the trunk of a 96 Cobra comfortably and still leave room for a battery relocation. Soon will add tweeters and components that will probably need their own amp. Im looking for spend around 3-4 hundred dollars on a sub and amp, i know its not much but im buyign that cobra so....all ive got for now. I might hold off on the system though so just let me know please.

Hey Bones...
If he is using 1 4ohm or a dual 2ohm sub with this amp, he could have some issues. If he is using the amp bridged and shows it a 4ohm load, he is in fact showing each channel of the amp 2ohms. This will be a problem if the amp is only 4ohm stereo stable.
I will say that this is stated based only on the information that is in this post.
I hate it when manufacturers rate their product output at 14.4v. Why announce that we have crappy regulation curcuits?
What are you talking about???? A 4 ohm and dual 2 ohm sub both run at 4 ohms, and the amp runs at 4 ohms bridged, so how is he gonna have any problems???

If he is using the amp bridged and shows it a 4ohm load, he is in fact showing each channel of the amp 2ohms.
What??? This is false.....in fact I dont even know what you are trying to say but its wrong. The amp bridged is 4 ohms. If he shows it a 4 ohm load then he has matched the ohms of his amp to the ohms of his sub. When you bridge an amp you dont split the ohms. This would mean that you would have to have an amp bridged at 8 ohms to run a 4 ohm sub. Thats totally ludicrous!! The only thing you split on a bridged amp is the amout of watts by how many subs you are running. For example a bridged amp (or any amp for that matter) running 400W x 1 to 1 sub is 400W to the sub, by 2 subs is 200W to each sub, by 3 subs is 133W to each sub, by 4 subs is 100W to each sub and so forth and so on.

OK, first off please read the whole post before you start trying to tell some one how wrong they are. I corrected myself and stated that that particular amp is infact 4 ohm stable in bridge mode.
Second, IF you don't know what I am trying to say then maybe you should do some home work!
Let me try to explain this in a manner that might be understood. When an amplifier is placed in bridged mode, both sides of the amp work together to share the load. Thus each channel of the amp takes on half the load. If you place a 4 ohm load on the amp when it is bridged, shows each side of the amp half the load. Now lets look at it more closely... half of 4 is...2. So in effect, Each half of the amp works with a 2 ohm load. Hence the higher output, but not all amps can handle 2 ohms per channel. Most do, but in Bones' original statement, he noted that the amp was only 4 ohm stable in STEREO.
You state:"When you bridge an amp you dont split the ohms. This would mean that you would have to have an amp bridged at 8 ohms to run a 4 ohm sub. Thats totally ludicrous!! The only thing you split on a bridged amp is the amout of watts by how many subs you are running."
To state this is to say that if you try to pull a 2000lb trailer with 2 trucks, they both still pull 2000lbs when infact they are only pulling 1000lbs each.
It is not the amplifier that determines the load that it is running. We are simply provided with the recomended load to run on the amplifier and what output we should expect under those conditions.
If you don't think that both channels of the amp don't share the load, then shy do manufacturers tell us that the same amp that it 2ohm stable in stereo, is only stable to 4ohms bridged?

Stop saying "the amp is so and so resistance" because it isn't. Seconldy, do not criticise what others are trying to say because your posts make very little sense. You you need to brush up on either your knowledge of the english language, or your knowledge of electronics. I can't quite figure out which just yet.

If he is using the amp bridged and shows it a 4ohm load, he is in fact showing each channel of the amp 2ohms.
This person is attempting to say running a 4 ohm load over two channels means that each channel sees 2 ohms.
