Hey All,

I have an Alpine MRX-M240 amp powering a single Alpine Type X 12 inch sub. The capacitor I have on it is the Rockford Fosgate RFC10HB (10 Farad hybrid)

Amp = Alpine MRX-M240 X-Power Series mono subwoofer amplifier — 2,400 watts RMS x 1 at 2 ohms at Crutchfield.com

Sub = Alpine SWX-1243D Type-X 12" subwoofer with dual 4-ohm voice coils at Crutchfield.com

Capacitor = Rockford Fosgate RFC10HB Hybrid 10 Farad Digital Stiffening


My problem is I still get dimming of my headlights. Am I doing damage to my cars electrical since I can still see the dimming happening? The Capacitor did help a lot....however it is still noticeable if I have the volume up.

Do I need to do anything else to my car to prevent damage and/or fix this problem? I have heard of people buying a high output alternator I think.....would that solve it entirely?

Just curious as to what people recommend. :06:

The problem is due to the distance between the stock alt and the battery, so not much, outside of upgrading the alt would do much to help.

I don't believe any damage is being done by the dimming, however.

Have you done the big 3 upgrade yet? If adding the cap helped you, maybe upgrading the big 3 will be effective as well.

Oh.....I didnt even think about that. Ill have to check. I know I bought a wiring kit with 0 gauge wire to ground it and I guess maybe it was used to hook the battery up. I was thinking about upgrading my alternator if my current one ever goes. I saw that for Chrisyler 300s there are 4 different grades of voltage output am I right? The top one being over 500 bucks. Do I need to do anything other than just install the alternator?

I'm not sure what's available aftermarket for our cars and whether they come with external regulators or not.

As far as I understand the current voltage rating of your alt would depend upon the trim level.

you would have either a 140 amp or 160 amp stock alt.

As for the big 3 upgrade, there is a sticky here that explains it all.
