You can do the following to get better bass output:

1. Better: Scrap the stock sub woofer for an after market 2 ohm, dual voice coil unit in a ported enclosure built to the manufacturer's specifications. Hook this unit up to the stock Infinity amp.
   
2. Best: Add an after market amplifier pushing at least 200 watts plus an after market sub woofer in a ported enclosure built to the manufacturer's specifications.

When I got my JK the first thing I did was take out the stock sub woofer and put in a Kicker 2 ohm, dual voice coil S8L7 in a ported enclosure built to manufacturer's specifications. This sub was hooked up to the stock Infinity amp and easily produced twice the bass output as the stock sub woofer did.

After 6 months I decided to install my after market Kicker amp because the sub woofer's output was not powerful enough. I used the stock sub woofer wires as my source into the high level inputs of my Kicker amp which feeds the after market sub woofer I mentioned above. This setup, which is only pushing 200 watts, is more then powerful enough to feel the bass in the seat of your pants.

Good luck.

This is because we are all individuals and our opinions of what constitutes quality bass output is as unique as our individual personalities. I will say that I think you would notice an increase in bass if you put that sub into a properly built PORTED enclosure. The key word being PORTED. Generally speaking, a ported enclosure would double your output because the box is utilizing the speaker back wave to enhance the speaker's front wave. In contrast, a sealed enclosure does not utilize the speaker's back wave so the only audible output is coming from the front of the speaker.

When I added my Kicker S8L7 and a properly ported enclosure to the Infinity stock amp I immediately noticed an increase in bass output over the stock sub woofer. Please keep in mind that even though I was satisfied with just the addition of an after market sub woofer in a properly built ported enclosure you may not be. It really depends on how much punch you want. If you like bass notes that vibrate your sternum then this setup may not satisfy you and leave unhappy with your purchase. If this is the case, then this setup is still a great middle of the road solution because you can just pony up for the sub woofer and box right now and then in a few months or so you can always add an amplifier to get even more bass.


Good luck.

If you research the concept of using poly fill or fiber glass you will undoubtedly read differing opinions on if the theory truly makes enough of a difference for the human ear to perceive. In theory, the fill material disapates heat and reduces the velocity of the speakers back wave thereby tricking the speaker into believing it's in a larger enclosure so it plays lower and louder. Many people claim they can hear a difference while others state just the opposite.

From my research I've determined that filling the enclosure with poly fill or fiber glass is subjective to the listener so the only way to determine if it works for you is to try it. What is generally agreed upon is that the fill material does an excellent job of reducing enclosure resonance which in and of itself can increase a speaker's efficiency resulting in louder and lower output.

I will say this, if you add poly fill or fiber glass to your enclosure you shouldn't expect miracles. It won't make your 8"/96 watt sub woofer sound like a 10"/200 watt sub woofer but it will reduce enclosure resonance and help in extracting the most efficiency from that specific woofer/enclosure combination that is possible.

Poly fill can be had from WalMart for $2.00 or so a bag. It definitely won't hurt to pick up a bag, add it to your enclosure and test the results for yourself. If it doesn't do much then you're not out alot of cash and you can start focusing on a different solution.

Good luck.
