|Dremin2flyhi||Some Clarity on SENSITIVITY-- is rated dba (decibel A-rated/weighted) output that a speaker can deliver given usually a 1KHZ tone at 1 watt at 1 meter distance from the measuring source-- usually a Spectrum analyzer or Sound meter . So the higher the number is-- the sound output is louder .. But keep in mind-- you probably will not be able to tell a difference in speaker that is 84.5 or 87-- but you can tell a difference usually above 5 dbs or more.. Then a speaker rated at 91 or 92 dba will be louder at the given input wattage compared to the 84.5 or 87 speaker.|

Sensitivity is the clarity of the speaker. It is how manufactures quantify how crisp and clear a speaker sounds.

PS - When all's said and done, it's what's satisfying to your ear that counts.

First, amps DO NOT boost the frequency. They boost the power thereby making what ever frequency coming out louder. The frequency will be based on the weakest components. For example a head unit that has a range of 35-30K with an amp that has a range of 60-32K and a set of speakers that has a range of 55-36k. The sound you hear will have a range of 60-30k because the head unit has the lowest high range and the amp has the highest low range. The amp will only make that sound louder.
Second, tweeters don't make more bass. They don't make bass at all, but I do understand what you're getting at. What you meant to say is to use component speakers where the tweeter is separate and the woofer is unobstructed.

Well lets see what the numbers say. These are based off of the best 4x6 speaker that will fit the Jeep dash from each manufacturer. I threw in a few other brands just for fun.
Boston Acoustics S75
- Frequency Range: 70Hz-20KHz
- Sensitivity: 92dB
- Power(RMS): 35W
JL Audio Evolution C2 400x
- Frequency Range: 71Hz-22KHz
- Sensitivity: 84.5dB
- Power(RMS): 35W
Infinity Kappa 462.9CFP
- Frequency Range: 75Hz-25KHz
- Sensitivity: 94dB
- Power(RMS): 60W
- Frequency Range: 93Hz-22KHz
- Sensitivity: 87dB
- Power(RMS): 45W
- Frequency Range: 45Hz-30KHz
- Sensitivity: 90dB
- Power(RMS): 20W
- Frequency Range: 25Hz-33KHz
- Sensitivity: 89dB
- Power(RMS): 30W
You can see JL Audio gets schooled. Boston Acoustics has the same frequency range just at a lower level but the sensitivity doesn't measure up to the Infinity. The Pioneer and Sony ones surprisingly have the best frequency range by far but they don't have the sensitivity to match. Infinity also has the highest RMS power rating out of all of them.

|Tazman2||do not go with infinity, if you want a decant sounding sound system go with something like JL audio. I had infinity their crap. ether way you look at it if you want high performance sound from using upgraded speakers using stock equipment you will need some type of amp to boost the frequency of the speakers. and if you want a little more bass use tweeters. we just got done with my buddies 09 JK and it sounds awesome. He did the whole system for under $300. I know its not cheap but If your looking for high quality it will cost you. we re fabed his sound bar so the tweeters and amp fit so nothings on the floor and you don't have to worry about it getting smashed. unless you roll just my 2cents.|

|KawiTJ||thanks alot... i thought the infinity did sound clearer... ill just let the boss in for now... would like to fix the rigged wireing that was done by the previous owner, but its a little cold out for that. heres a pic of the infinity speaker i have|

Infinity for sure. The wattage doesn't mean crap when it comes to sound quality. Frequency response and sensitivity are the things your going to want to compare. You'll have to get the model number off the back of the speakers and look up the specs on each set of and compare them.
Frequency response - the wider the range the better
Sensitivity - the higher the number the better
But I'm sure the Infinity set will have some better numbers than the Boss set will.

Problably the Infinity. but having a look at the specs should speak volumes.
the majority of the weight should be the magnet stuck to the bottom.
I've really never seen the need for a maximum watt rating other than as a 1/2 false use for advertisement. as the vast majority of people under drive speakers...thus blowing them out with distortion when they try to crank it up.

infinity vs boss speakers
I have a set of infinity 4x6 speakers that are 145 watt I think and a set of boss 4x6 speakers that are 200 watt... anyone have an idea which are better? The infinity has a plastic base and the speaker overall weighs way more. The boss has a metal base.
