Question: I have a car audio bass system installed into my Honda civic type r that has multiple loud powerful big subwoofers in the trunk. Its really loud, in fact so loud that when the bass hits my headlights seem to dim with the beat. I have been recommended by a few people a power cap. Now they look very flashy to go with the system, but do they provide any purpose besides a Christmas decoration?
Answer: Yes a power cap will help stop your car headlights from dimming because it acts as an reserve storage of energy. When your amplifier does not need it, the power cap will store it for a short while, when the bass drops it will release it and feed it into the car amp. They come in different sizes you need to ensure you get the correct farad for your overall wattage of the system. Also the fancy lights you mentioned is a volt meter that shows how much drops there is placed on the electrical system which is also another handy feature. It also lights up blue or red depending what make power cap you are using which also looks cool when you open the trunk.
Car Audio Capacitor Vs Battery?
Update: Now a few people have been discussing that power caps are a waste of money. Now being experienced technicans, they do serve a purpose and they get the job done well. I mean if you are going to compared it against adding a second battery such a yellow top optima deep cycle one then thats obviously is going to perform better. But you got to think that it costs nearly three times as much plus you have to relocate a second battery using a isolator which can get a bit advanced for a normal person. For the price power caps retail at and what they provide they are certainly worth it all day long for any basshead in the car audio scene.
