This build will be gradual so bear with me The Sub is a DC lvl3 18 with lvl4 upgrade, powered by a BC2000d @ 1 ohm. I have a 300amp Singer that i got from a member here, as well as an optima 34/78. I also have an XS D1200 en-route. I started by building the port. .375 roundover on all port edges. I should have waited to route the front of the port until the box was complete though. i Had to fill in the corners with bondo and go over them with the router a few times to get them perfect. If i would have thought about it before i started, i could have saved myself a lot of time. A also completely forgot to subtract the volume of the port bracing from the total port area... You live and you learn, right? Working on said port bracing. Used the C-clamp to keep the ends of the smaller pieces of mdf bracing from splitting. I like to drill pilot holes on the small side...

Good morning everyone. I'm posting this because I was up until 2am diagnosing a voltage drop problem, after installing my additional battery bank (2 Advanced AutoParts Platinum AGM's, 2 in rear, 1 up front). After installing the bank, I went from 13.8 volts at idle, to 13.4. I was scratching my head saying WTF??? Now, my voltage drop steadied out drastically, but I still lost a critical .4 volts somewhere. I want it back! What happened??? Well, I checked all my grounds in the rear. One from negative battery post of one battery straight to amp. Another from same negative battery post to chassis. All good! Move to the front of my car to check what I thought was my Big 3, or 4 in my case. Checked the Chassis to Negative battery post, Good. Checked Alt to Bat Positive, Good. Checked Alt casing to battery negative, Good. I thought this would suffice as an Engine to Chassis ground, as it was tied into the same ground wire that came from my chassis. MAN WAS I WRONG!!!! I FINALLY located the braided wire that went from the top of my engine block to the chassis. I added a 12" piece of 1/0 OFC from engine block ground, straight to the strut tower. BAM!!! SOCK!!! BOOM!!! (Remember the old Batman episodes? Some may be to young to remember. Anyway, off point now. Damn ADHD!), my voltage immediately came up from 13.45 to 13.9! I gained .45 volts with the addition of that one wire! HELL TO THE YEAH!!!! Now, I will be adding a second ground in the rear from the second battery in the bank, to the chassis. That battery has no grounds coming off it, so I will give it a dedicated ground as well. Maybe I can gain another 1/10th or .2 and finally get my voltage over 14? I will be back later to confirm my results... Just thought I would post this to reiterate the IMPORTANCE of proper grounding. Everyone, myself included, is always concerned about POWER POWER POWER, while proper grounding always takes a backseat in our heads. At least it does in mine, and I am being brutally honest right now. I have now learned that your grounds are just as, if not more important than the actual positive runs in the car. I can't stress enough how important is to ground properly people. If this helps at least one person out there, then I'm glad I took the time to post this. Good luck out there!
Hi ! Just would to know if somebody know the brand "hollywood" and if their cable are good stuff, I will have ~ 1200 wrms, and I plan to buy this kit: http://audio-video-mobile.fr/kit-de-cables/59-hollywood-kit-de-cable-cca20-53-mm.html Thanks !
