Is a 4 farad power cap better than a 300 or 400 capcell.

Neither.

"The capacitor charges and discharges rapidly, much faster than a battery could. It can only hold a small charge, so a single bass hit can empty it completely. It charges back up when there isn't a large power demand. This makes it inappropriate for systems that will require prolonged delivery of power, as the capacitor cannot supply additional power, only store it temporarily.

A power cap will not help if an audio system requires more power than the vehicles electrical system can deliver. While this usually requires upgrading the car's battery or alternator, a low-cost improvement is to upgrade the "magic three wires."

They do make a harness that plugs into the factory speaker harness, but we never use them. The Tan and the Light Green wires are the positive wires.

Remove the speaker, cut the plug and wire off of the factory speaker. Connect the positive wire of the new speaker to the positive wire of the vehicle. Connect the negative wire of the new speaker to the negative wire of the vehicle. Make sure your connection is insulated and there are no bare wires that can touch the chassis of the vehicle. Mount new speaker and put door panel back on.

Depends on what you are looking for a more SQ style sound or to play loud. Judging by your choice of 2 15s i would say you want something to shake the ground. Go ported.

you cant have both. You either have true SQ or you do not. Ported will still sound good. But it will not be true SQ.

Please elaborate on this comment. Are you suggesting that you can not get true sound quality from a sealed enclosure? If so, I disagree.

The Kicker cvr gives a much flatter output curve with sealed rather than ported. Meaning It would be more ideal for achieving a more "True" SQ sound. Ported narrows greater output to a smaller freq range making it not as ideal for achieving "True" SQ. Yes you can have a happy medium of output and still sounding good. But that is not true SQ. They are far from the same.

What do you mean by flatter because I thought like this go with the sealed box becasue a big truck is like a port itself with all of that space but some guys say since I like rap music go with the ported box but others say go with sealed and some notes will sound better. I have a sealed box now and posted this forum because I was thinking about getting a ported box

What i mean by flatter is to the responce of the sub in DB terms. For true SQ you want to try and achieve the flattest curve possible all the way down to the bottom freq. If you are a rap guy im betting you want some ground shaking as i said before. Your looking for more output. Ported will definaty do this but is going to sacrifice a more true SQ sound although it can still sound good. I my self run ported Kicker L7 15s They sound great. I listen to almost every kind of music. For rap it will more than make you happy. If you are looking for more output and something that is going to still sound good then yes this can be done. The problem is there is always going to be compermise. With more ouput in certain frequencies you are giving up SQ and for more SQ you are giving up output. If you want a happy medium then yes you can go ported.

Can you go any larger? That is only 3.31 cube per sub. Then you have to subtract the port which is .64 per sub only giving you only 2.67 cubic foot per sub. That puts it under what it needs to be for the minimum ported encloser. If you dont have anymore space your best bet is to stay sealed from both an ouput and SQ standpoint.

That would be enough to work with to make the smallest ported enclosure. Would you like me to give you some exact specs for the box?

42" W x 17" H x 22" D overall outside dimensions. Do an air tight baffle between the 2 subs(giving each sub its own chamber in the enclosure)and 1 port per chamber. Ports will be 2 3/4" W x 15 1/2" H x 25 3.4" L( you will have to fold the port) FB=35Hz

No problems. Keep in mind this is the smallest recommended ported enclosure. If you could gain more space it could be louder and sound better. But we are talking 2 to 4 cubic foot larger than what i have just done there.

my bad...I meant true sq enclosure. You can get fantastic sound quality from a sealed enclosure. I'm saying is that sealed is not the only sound quality enclosure there is. Ported can sound just as good designed correctly. IMO my old school 12W6 sounded MUCH better in my transmission line than it did sealed. In the t-line the accuracy was shocking. Every note was defined. Sealed it was ok. The quick double kick drums weren't as detailed.

I see too many ppl always say. sealed is for sound quality and ported is for spl. Not true at all. In some cases sealed will have more output than ported.

it should be ok. its pretty close to the spec i gave you. The port should even be close to what i gave you as well judging by the pictures. But there is no way for me to be sure with out having true measurements. A custom box would be better. But if you cant build or find someone to build that one should work.
