[QUOTE="Joe89, post: 7867073, member: 583644"] Personally, I would not install the capacitor. Your amp does rated power or close to it. If you have a relatively strong stock alternator, 1700w requires that you either be diligent with your volume control, or you do something to improve your electrical. For example, if you had a 150a stock alternator, an additional battery (with an isolator) could be all that you need. My advice is to install the system and see how it goes. You might not have to add anything beyond the Big 3 wiring upgrade. If you have a weak stock alternator, I would advise replacing it with a high output model. One big area is almost always slightly louder. It is also easier to build. One drawback is that in the event that one of your subwoofers fails, your other subwoofer will be functioning in an enclosure 2x too big, and it won't be functioning for long if you do not realize you have a blown woofer. I do not believe shared ports versus individual ports have as much of an impact on the sound as does a shared chamber versus separate chambers. However, if you do not build the box precisely, the two ports at slightly different tunings will not be as efficient as a shared port which provides your enclosure with its one intended tuning.
