I have 2 12s being pushed by a 1500 w amp and my mids and Highs are being run by 400 watt amp. Every time the bass hits I have a voltage drop. If I play my stereo hard and continuous for about 5 minutes It'll slowly drop more and more and more until it's hitting between 11 and 12 sometimes drops below 11 and my battery light comes on in my truck. I'm not sure how to fix this besides getting a higher amp alternator. My alternator right now is 136 amp in my Dakota. I've done the Big 3 upgrade and I have a yellow top Optima. I have a 12-volt auxiliary battery connected to my sub amp. It's one of those small ones that look like they're going to lawn mower. I have a 6 gauge run from a battery back to my amps and then everywhere else in the truck is 0 gauge. I don't know if this matters but I upgraded my door speaker wires to 12 gauge running straight from my amp which is a JBL gx-a604. I have my two Sundown Audio 12 wired down to .5 ohms. And have a Sundown Audio sa e 1500 pushing my Subs. I'm trying to give all the information I can so you guys can have all the information you need to give me proper guidance. So if I'm all over the place that's why. I think that might be it if anybody has any questions let me know but if you guys could help me or give me any suggestions that be great but I have a feeling I'm going to have to upgrade my alternator. Another thing is my headlights never Dim when the bass hits but my dash lights do. So if anybody has any ideas I appreciate your time
