Bronze Member Username: Malby7Post Number: 11 Registered: May-04 | I've tried to read all the posts on this sub but none of them have been specific enough to my system. I am in the midst of revising my system and what I intend to have is the following: DECK: (1 x Pioneer DEH-P7500MP) http://www.crutchfield.com/cgi-bin/ProdView.asp?i=130DEHP750&search=deh%2Dp7500mp Door Speakers: (4 x Infinity 6802CF) http://www.crutchfield.com/cgi-bin/prodview.asp?s=0&cc=01&i=108680 2CF&g=52200&search=infinity Speaker Amp: (1 x JL Audio 300/4) 75 Watts RMS x 4 @ 1.5-4 Ohms Sub Amp: (1 x JL Audio 500/1) - 500 Watts RMS Sub: (1 x JL Audio 10W7) - 500 Watts RMS My questions are: 1) Will the system run fine on the stock electrical system of a Ford Focus? If not what options do I have to correct this problem? 2) What type of box should I get to have the best performance out of my sub and save as much trunk space as possible? If I get a sealed box will I have enough bass with the 10W7 and 500/1? 3) If you have any other suggestion about anything having to do with this system please let me know I want to do this the right way! |

Don't get a cap. Place that 10W7 in a sealed box. You will have a lot of clean, solid bass. It will put out plenty of bass. You will be suprised. |

Anonymous | capacitors only help if the charging system is up to par. For example, have you ever had a dead battery due to an alternator/regulator problem or seen someone who has? You can jump start the car, but it will only run for so long until it dies again. A capacitor is more for power on demand than helping the charging system. An alternator is the way to go. |

Bronze Member Username: Malby7Post Number: 13 Registered: May-04 | OK, so far I like what you guys are saying about getting a sealed box. I would like sound quality. The only question I have is, will a ported box be that much more powerful than a sealed box? |
|
loud and low Unregistered guest | a ported box will only be louder at the tunning frequency about 3db. it also produces a different sound. Personally i prefer a ported box tuned very close to the drivers fs but its only a matter of opinion and most people prefer a sealed box for sound quality. listen to glasswolf he knows what hes talkin about. go sealed |

Gold Member Username: GlasswolfNorthWest, Michigan USA Post Number: 3060 Registered: Dec-03 | listen to both. see what you like. ported is more ifficient by +3dB. sealed is a flatter response, but uses more power to get the same volume by a bit. a sealed box is quite a bit smaller in volume for the same sub compared to ported. |

Anonymous | there are certain differences between a ported and sealed box. for a sealed box, it keeps the coils in line better making the sound better quality, although, because it is sealed, whenever the driver moves out, it creates a vacuum inside the box which dosnt let the driver move out as far. a ported box does a few things. it will sound louder because of the airflow, it will do better with the high bass and it is more efficient. because the w7's are high quality, i would go with a ported box. but its totally up to you. |

Anonymous | you also may want to think of upgrading your alternator (dosnt matter with any kind of car) because the two amps suck up almost 100 amps. you will also need a 2 gauge power cable for the main power. f*ck capacitors. they are usless. |
|
Anonymous | another thing, check out jl audio.com and download their owners manuals for the sub, and amps. i did and they are very useful. jl audio themself will tell you that a ported box is recommended. |

Anonymous | i have a 2003 altima and i never really heard about charging systems being a factor but i have i brahma 15 in a ported box on a jbl 1200 coming and would that charge system be alright? |
