You're running 2 amps right ?

And 600 Watts Max ? So that'll be 300 per channel and if it's a really efficient amp you're looking at about 150 watts per channel, so 300 RMS. That's not to much of a strain on the factory battery and alt.

The cap will just work as a temporary fix, I'm running a Hifonics Brutus 1200 and a 1400 watt 4 channel with a cap, my headlights don't dim since i'm running HID's but my dash lights do dim a bit. I'm going to have to upgrade the stock battery and possibly stick a smaller one in the back close to my amp that is running my subs, to see how that works, after that i'll replace the alternator.

Yes, two amps. One is 500 watts, for the sub and the other is an RMS of 60x4. This is running the 6x9's and the 6 1/4's. Honestly, I probably won't do anything for now as I only notice the headlights dimming on that one song when it was pretty cranked on the volume. I still may look at a cap though. Thanks for that suggestion.

Here's some pics of the ported sub box compared to the sealed sub box and how the sealed box sits in the trunk. I have the angled back of the sealed box up against the rear seats.







14lbs for the sealed box, no speaker:


24 lbs for the ported box, no speaker:


Stuffing some batting into the sealed box:


In the trunk. I had to elevate the box up about 3 inches so that the angled back would sit flush against the rear seats. I used heavy duty Velcro to secure it against the seat back so it wouldn't move around under heavy cornering.


Takes up less room in the trunk, faces the right way for maximum thump and weighs 10lbs less, I like it!
