Okk yea ill get the sketchup for you tomorrow. My big 3 was a bitch to do because of how the alt was. Sometimes it sucks to do the big 3.

That should be good. Are they flared though? 2 6" was how much I was trying to get for my Zcon 15 but it didn't work.

I ran it and it was totally fine. It was as easy at regular car audio wire.

It allows for better airflow. It's not really a major benefit, but I always do it. If you want to do it I can put them in. If you don't it's fine. Also do you want the sub flush mounted?

Okk that's fine. Just make sure you can fit your dimensions through the opening of the trunk. Do you want 45s in the port and in the corners of the box? Are you having the box facing rear with the port?

So for the design, what do you think? Your max dimensions were way more than needed so I cut down a few inches on the width and depth. If your all good I can start up a 3d design.

What about your thoughts on the big three on adding wire vs replacing? What is the welding wire? is it just "welding cable" that I'm looking for? sorry what is OFC? Should I use this for all my 0/1 Gauge wiring? Ok so Dual 2 Ohm VC is what I want. I think that's good then I can run the sub at 4ohm's on completely stock electricals, OR if I get the upgrades done I will wire it to 1ohm. I like that it gives me the flexibility. How does that sears battery differ from the ones that I see sold on SSA? Add the wire right to the existing wire. If you need clarification on the big 3 let me know. Yea welding cable is what your looking for. https://weldingsupply.com/cgi-bin/einstein.pl?Next::1:UNDEF:OR:terms::PA#A2 Here's the welding supply.com website. I would get 1/0 gauge. However many feet you will need. Just get the black. You can get the flexible orange but the black is flexible enough for what your doing. There's two types of wire you can get: OFC (Oxygen free copper) and CCA (Copper clad aluminum). OFC allows more current to go through but is a little more costly than CCA. at 4 ohms you should still have the big 3 done though. They're the same type of battery, the sears and XS power. An agm which is a deep cyle. These are the types of batteries you need for car audio. Both will get the job done, but I think the XS Power your paying more for the name. Don't get me wrong, they're great batts, but for what your doing the sears is cheaper and will still do the job great.

So what I came up with for a design is: 16.5H x 30W x 21D Port: 15H x 4W x 44L I put in a double baffle on the front. All this comes out too 2.8 cubes tuned to 33hz with 60in2 of port area.

I'm dumb. I forgot you said Passat! If you do get a second battery I would say run it at 1 ohm then. Look at this batt http://www.sears.com/diehard-platinum-marine-battery-group-size-34m-price/p-02850134000P?prdNo=2&blockNo=2&blockType=G2. It's a g34 and will be plenty for your bc2k. I have the g31 which is bigger and it's a great batt. A lot of people on here use it and love it. The way you said to wire the second batt will be fine. I would use some welding cable. Much cheaper than car audio wire and it's OFC which is better. Welding supply.com has it but another place is cheaper. I'll try to find it. With the efficiency of the amp, the lower the ohm load the more current (amps) it will pull. I'm not really sure how to explain it in details, but that's what happens. Dual 2ohm can be wired to 1 ohm and 4 ohm and Dual 1 ohm can be wired to .5 ohm and 2 ohms. That's with a single sub. So in your case you will want a DUAL 2 OHM. If I were you I would go with the diehard platinum g34 and have it as a second batt.

You'll learn a lot here! Welcome to ssa!

The Xcon doesn't need a lot of power for it to be loud. Which means it doesn't need the full 2k rms or even it's 1750 rms. People run them on 600 rms and are very happy with the output. We can just make your box on the bigger side to compensate for the low power. If you don't have the money or just don't want to get a second battery right now I would suggest running the amp at 4 ohms. This way it'll be more efficient and you won't have to worry about putting strain on your alt, battery and equipment. Your amp puts out around 700 rms at 4 ohms. I've had two and they're great amps. Adding a second battery is easy. What I did was run a pos and neg wire from the front batt to the second batt. You can run just the pos to the back batt and ground the back batt in the trunk. That's good you can build the box. It's way cheaper than buying and you get experience doing it. Personally I love to build them. For you tuning I don't think you need to tune that low for your type of music. With me I had a 12" Zcon tuned to 32 hz and hit decaf's low music (28 and up) like crazy. Now I have a 15" Zcon and and it's between 33 and 34 and I don't hit that low like I want, but still able to hear it pretty good. With my tuning at 33-34 it sounds good with the dubstep and electronic music I listen too (I like a lot of that music). So for tuning I would go with 33hz if I were you. I'll put in the measurements and see what I come up with. Awesome that you have the 180 alt. Is it dodge charger? The volt meter is good because it'll let you know how much of a voltage drop you have and if you need more electrical upgrades(second batt). And with doing the big 3, it's no problem doing it on a new car. I have the big 3 done on my 2012 fusion.

No the gain doesn't work like that. It's not a volume knob. All it does is match up the voltage from the head unit to the amp. I set mine by ear and set it to right before the sub distorts and has stress. I would highly suggest a battery in the back in addition the the front. Can you build your own box? I can get you a design and a 3d sketchup for you to help you build the enclosure. You can have the tuning and size to your preference depending on your max dimensions.

Make sure you listen to these guys. They absolutely know their shit. Alton has helped me with multiple boxes and has explained everything behind it.

Welcome! Some great people on here.

What subs do you have?

Never said you did lol I said I did since it's not made into a 12 either. Although it would be nice if both popped up!

Same here So yea hint hint, Aaron and Mark haha

That'd be cool if they were made into a 12. Same with the SSA Evil. I might try an Evil if it was made into a 12.

Happy belated birthday haha nice alt!!

Sorry no trades

Yea it sucks. Not really there fault though..

I ordered a set of mezzo comps back in nov and still waiting. It's not to big of a deal. I guess ill throw in my audioque coaxials until they come. My stock speakers don't cut it at high volume.

Somebody make me an offer

Come on someone buy the amp!

Pioneer makes good radio's 4) Every thread should start with a detailed background including what vehicle, equipment, and goals you have. The more details the better. Everyone knew what he was talking about. Only thing he was missing is budget but he quickly stated it. He knows what he's doing anyways so I'm pretty sure he's good lol
