Problem with Setup, need help

[Rhys2005]

Okay i have a 12" Alpine Type X with a MRD-M1005 powering it, Stock head unit //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif 4AWG Power Wire 3 ground wires, and its in a custom sealed box i made. When i first hooked it all up it bumped fine, kept that full bass and power, now i seem to be having a problem with the sub getting louder and decreasing volume like a wave. I dont know if its that i need a capacitor or whatever but i can tell you my headlights, interior lights, everything dims. What could the problem be? Thanks

If it played fine before, looks like your alty could be going out. What do you mean by 3 ground wires? Did you do the big 3?

Well what happened was i never had gotten a 4AWG ground wire, so i used 2 8AWG and 1 10AWG wires to ground my amp in different locations. What is the big 3 btw, ive heard of it but never learned what it was, and would a capacitor help my problem at all? Maybe i am going deaf lol

big 3 is replacing wires between alt/batt/grounds under the hood

could be that your ears are just used to it now. i know im used to my XXX at full tilt off a 2500d and three batts lol and i know for a fact i have hearing loss //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Well i have a question, what should my amp be set at usually, gain goes from .1 to 8.0, LPfilter 25?-200, LP slope 12-24 DB, Subsonic Fileter 15-30db, and bass boost 0-18db. If anyone knows thatwill be great, i mean i have a stock head unit so setting the amp is difficult. i mean i may be getting used to it and have hearing loss, but for example, theres one song right now that i play on my system and it bumps loud as hell and theres no clipping/damage being made to my sub, i dont understand? the songs that used to be loud arent. BTW how easy is it to get hearing loss?
