which would you prefer for subs... (2) 12" Infinity Perfects, or (2) 10" Kicker L5s? i want to give them 400 watts each in a sealed enclosure in the back.. and since both require relatively small requirements.. i dont know which ones to pick. im leaning a little more towards the perfects, for soundquality and all.

as for an amp... i was looking at a kicker 800.2 or 400.2... depending on the ohmage of the subs i get. but will the 400.2 kicker amp give me 800 watts bridged at 2 ohms? will that be safe for the amp? id either go with the 400.2 and bride it at 2 ohms, giving me 800 watts, or id bridge the 800.2 at 4 ohms and get 800 watts... who knows, just give me som einfo on that 400.2 amp

thanks :lala:

 

As for your sub choice, just buy the ones that sound the best to you. I hate these questions on the boards, because who am I to tell you what sounds good to you. Use your own ears, and make your selection. I really don't mean to sound rude here, but barring obvious defects or poor quality for the subs in question, how they sound is purely a subjective matter, best settled by your own ears. After all, YOU have to listen to it, not me Toss into that how a set of subs will work with your amps and existing speakers and source unit, and you can begin to see my point.

As far as the amp choice is concerned, get the most power you can afford, and throw power ratings out the window. A properly adjusted amp, even if it exceeds the power rating of a speaker by 2X is better than a lower powered amp. More power = more dynamic headroom, and your amps will be able to deal with anything that comes down the pike, signal wise. What most often kills speakers is a distorted signal, not good, clean power. Gain controls are not volume *****, they are there to match your amps with the output from your head unit. Done properly, you could easily run speakers rated for 100W with an amp that outputs 1,000W without any fear of destroyed equipment, although this example would be overkill.

 

Sorry, let me be a little more to the point here. I don't have any problems with either Infinity or Kicker, either one would be a good choice, quality wise. The 2 12" subs will give greater output (obvoiusly), no matter what wattage applied to them. Your next choice should be based on where you will mount a box, and how much space you are willing to give up. The size of the box for them is something you need to consider for any sub.

 

so even if i had a few hundred RMS over the reccomended power... i can adjust it to not murder the subs? id be scared to spend money on the subs.. and then get a nice kicker amp thats way too powerful and murder the subs... haha

all i want to know now is if the 400.2 is going to give me 800 watts at 2 ohms.. ill pay for the amp if i need to get another one... but there is a price difference between the 800.2 and 400.2, and id be concerned about paying a lot more for watts that im not gonna use

 

Nope, a few hundred watts here or ther shouldn't be a problem, provided that the amp is properly adjusted. This is a desirable situation, SQ wise, as the amp will not run out of power when presented with a large current demand. The result is clear and un congested sound, even when the musical **** hits the fan. There is a point of diminishing returns, so staying close to the rating of your speakers is something to consider from a financial standpoint, but don't let an amp that is rated above the power handling specs of your subs deter you from buying it. There is a common misconception that more power is louder, and while that may be true, the more effective way to gain SPL's is to add more drivers. The numbers bear this out, double the wattage, you get a net SPL gain of 3dB, if you add another driver powered with the same wattage as the other, you get a net SPL gain of 6dB.

 

Infinity Perfect. Thats it.
