Drop-in subwoofer upgrade?

[zhu-]

Has anyone come across a better subwoofer that's the same size and can run in the OEM box and amp? I'd prefer not to run additional wires, amps, etc. The factory one gets pretty loud but it doesn't sound that great. Curious to see if there are any simple upgrades available.

Don't know if this will help but people have been replacing their dead 12v batteries with a lithium battery and have stated much better results in their bass. Might be an option (although they're not cheap ~$450).

^^^^ this is a worthwhile investment anyway even if you want to go aftermarket.

im one of those cats who put this ohmu battery in my car and i noticed immediately the improvements in the sound system. several others on here have also experienced this and it NOT placebo.

I'm curious if installing a capacitor (10 farad or so) inline with the battery would net the same result; possibly prolong the life of the OEM battery.

Hmm that's very interesting because I swear my oem subwoofer sounded better before. I'm not too much of an audiophile but did do some focused testing between the 3's audio and my previous C300's Burmester upon delivery and get the feeling it sounds slightly worse now than back then.

Could the 12v battery have deteriorated enough in under two years for the subwoofer's audio quality to change? It sounds boomy and muddier now even on the same settings which have been mostly unchanged.

Everything but the propulsion of the car runs on this 12v battery. My 12v battery died and was replace yesterday. I only got 2 years out of mine. Extreme temps deteriorate batteries. Sad I only got 2 years. Also keep in mind these batteries are very small.

Did the car alert you when it needed replacing? I'll go for the lithium battery since it seems like it saves time and money in the long run in addition to potential audio consistency.

Is this the battery people are using?

The car did alert/warn me. Stated I had to replace it "soon". It died the next day. Ohmmu 12v lithium battery seems to be the one to go with.

Yes, may be cheaper on their website. Not sure about shipping costs.
