Q: The wiring here will be similar to wiring a single voice coil (SVC) sub-woofer. The difference to remember is that dual voice coil (DVC) subs have two coils, and thus four input terminals. Two of them are positive and two are negative. Choose one of the positive terminals and connect it to the positive bridged terminal of the amp. Just like wiring two separate speakers, the two coils within your DVC can be wired in series (increasing the sub's impedance) or in parallel (decreasing the sub's impedance).  If you are wiring the coils in series then run a wire from the positive terminal of the first coil (the one wired to the amp) to the negative terminal of the second coil and from the negative terminal of the first coil to the positive terminal of the second. If you are wiring the coils in parallel then run a wire from the first positive terminal to the second positive terminal and a wire from the first negative terminal to the second negative terminal. Again, you have the series verses parallel debate.  If you choose to wire the subs in series, connect the negative end of the second coil in the first sub to the positive end of the first coil in the second sub (these circuits can get complicated fast). Next, connect the negative end of the first coil to the positive end of the second coil. Finally connect the negative end of the second coil to the negative bridged terminal on the amp. If wiring in parallel, connect the negative end of the first sub's second coil to the negative end of the second sub's second coil. Connect the positive end of the first sub's first coil to the positive end of the second sub's first coil. Follow the same guidelines as when you connected the first sub's coils. Now comes the easy part. Regardless of which combinations of series and parallels you chose above to get the proper impedance and power distribution in your system, closing the circuit will be one easy step. Run a wire to connect the negative terminal of the second coil in your second sub to the negative bridged terminal of the amp. Power up your system and test it out. Start at a low volume and then slowly increase it to listen for anything that doesn’t sound right, like static or a difference in volume between the two subwoofers. If the bass and sub-bass are quiet or not present at all, something is mis-wired.
A: Wire the amplifier to the first subwoofer. Connect the two coils. Wire the second subwoofer to the first subwoofer. Connect the second sub's coils. Complete the circuit. Listen for inconsistencies.

Article: Satin stitching by hand takes precision. Practice on spare fabric first so you get a sense for how tight to stitch, and how to keep the stitches as close as possible. Start with a simple square or circle before trying intricate satin stitch patterns. Once you're confident with your scrap cloth, move on to a real project. Here are a few ideas:  Outline the edge of a garment. Monogram a project. Sew buttonholes with an extra-narrow satin stitch. When you feel ready, try a whole art piece with satin stitches. Remember to stick to narrow stitches only.
Question: What is a summary of what this article is about?
Practice on fabric scraps. Incorporate satin stitch in your design.

Q: It's important you understand the expectations of your course as you're studying. Use the syllabus as your guide if you feel overwhelmed or lost while studying. The syllabus will outline major concepts, grade breakdowns, and so on. For example, say you've been getting frustrated memorizing the years of major scientific breakthroughs for a science course. The syllabus says the goals of the course are to help you gain a better understanding of scientific theory. It's more important for you to understand the overarching theories than know the exact dates. Find peers who are hard workers and do well in the course. Ask them to form a study group. The right study group can really help you stay focused and engaged and gain a better understanding of course material.  Choose the right peers. If your study group is made up of friends, studying may turn into socializing fast. Pick good students who are genuinely engaged in class. Bounce off one another's strengths. If a classmate is confused on a subject you're skilled at, and does well in an area that confuses you, they would make a good partner. The two of you can help one another out. There is nothing to be embarrassed about if you have questions. Everyone gets confused sometimes and needs some extra help. If you have questions on a concept or subject, e-mail your professor or go to office hours. They may be able to offer you tips and tricks to better understand the material.  Your professor's office hours should be stated on their green sheet, which they handed out at the beginning of the semester. When e-mailing your professor, state your class day and time in the subject header. Professors often teach more than one class. Some teachers have review sessions each week or before an exam. Always make a habit of going if you have time in your schedule. Review sessions can help you gain a better understanding of course materials. They can also be a great place to ask professors or teaching assistants questions. If your teacher does not offer a review session, ask them if they are willing to do it. If enough students are interested in a review session, they may create one. If your campus has tutoring centers, make use of them if you ever need help. You can also look for a private tutor in your area online. A little one-on-one help can go a long way if you're confused about a subject.  Not all tutors advertise in the tutoring center on college campuses. Some tutors post their fliers on the school bulletin board, alongside other fliers for housing and textbook sales. If you cannot find any tutors, ask your classmates. Some of them may be willing to help you before or after class, and not all of them will charge a fee.
A:
Refer to your syllabus as needed. Form a study group. Go to your professors with questions. Go to review sessions if they are offered. Use a tutor.
