What are the Pro's and Con's of a Capacitor?

Well i decided to change things up and bought a kicker Zx700.5 so far so good it looks amazing, here are some pics. now for the new sub, i was thinking skar...only time will tell lol...

I am getting 15's very soon. Two aq hdc3's off of a 2200d. My electrical now is a 200amp alt, 1/0 big three, and yellow top under the hood. All this is on a diesel engine, that of course runs at lower rpms than a traditional gas engine. I have the smallest pulley I can put on the alternator already installed, and am scared the voltage may not be enough to back this system. Would another battery be needed? If so which one, and for the best price? By the way, this is a daily setup.

I am looking at a arc xxk4050 amp that is a couple months old he wants 300. for it. Is that a good price? the sheet says 118-120 watts a channel. I have heard a lot of good things about arcs but never heard more than a couple minutes in a demo room

Hello everyone, I haven't posted here in a while, but I've been keeping myself current on the threads in the build logs section for sure. Some of you might remember my build log, and might also remember that once I got to the point where I could finally fire the thing up, I was having lots of trouble with noise. I tested and tested, and it turns out that it is my JL Audio 500/5 that's to blame (I installed another amp in its place and the problem was totally fixed). It's a high pitched beeping sound that changes evenly in frequency (up and down). Sometimes it actually sounds like a pack of dolphins from the nature shows... very bizarre. It makes this noise in all chan…

Sundown SAE-1000D Rockford Fosgate T10001bd Memphis MCD1000 Phoenix Gold Xenon 1200.1 Am I even heading in the right direction in where to look for an amp? I'm pretty sure i've got it down between the Sundown and the Rf, but I'm open to all suggestions. Thanks. Jess

right now my battery is grounded to the front of the drivers side head (which is aluminum) i get a bit of noise every now and again through the front speakers and probably inaudibly through the woofers. the passenger side head is grounded to the chassis, above the motor. its all 4 gauge. i'll get a better ground by grounding the battery directly to the chassis right? then i just leave the head grounded above the engine the way it is? i know it needs to be bare metal, but can i just ground it anywhere thats metal on the body of my car, or does it need to be directly to the frame?

I would like to ask this question as a thought experiment to determine if I am properly understanding the following relationships with wiring and power. Our speakers get AC out of our amps and our amps get DC from our power system. The DC power does not have frequency as it is a single flowing direct current and as such the flow of electrons through any wire have ZERO skin effect as skin effect is only applicable with frequency of transmission. What does play a part in power capacity however is the material of which the wiring is made of and how it is made. The total measured DC resistance of a cable of X size will be lower in copper material than it wi…

I'M NEW TO THIS KIND OF SETUP SO IF I MISPRONOUNCE CERTAIN ABREVIATIONS, PLEASE FORGIVE ME, BUT HERE'S THE LOW DOWN....... I'M OVERSEAS RIGHT NOW IN THE AIR FORCE TRYING TO GET EVERYTHING FOR MY SYSTEM SO WHEN I RETURN, I CAN BRING EVERYTHING TOGETHER BUT THIS IS TRUELY MY FIRST TIME PUTTING A SYSTEM THIS LARGE TOGETHER SO I COULD USE AND USEFUL ADVICE U HAVE FOR ME. MY FIRST QUESTION IS.... 1. HOW DO I RUN MY BATTERIES AND IS THERE A DIAGRAM IN WHICH I COULD FOLLOW 2. FOR EACH ONE OF MY AMPS, DO I NEED TO RUN A SEPERATE CIRCUIT BREAKER? 3. DO I RUN THE POWER WIRE FROM THE ALTERNATOR OR FROM THE POSITIVE POST ON MY STOCK BATTERY WHICH IS A DURALAST MAXX YELLOW BATTERY? MY…

i was gonna see what you guys thought i have a 70 amp alt lying around and im gonna rebuild it...but i was gonna see if it is enough to handle the load of my amp (soundstream 2000d) i can make a bracket and fit it in and just use the second one for the stereo....i dont have 590 bucks lying around for a new mechman....i was just curuios if it could handle it.... thanks for all yalls help

I am looking for 4/0 wire. any recommendations for this type of wire. and where to get it

I have not been able to find an unfused distribution block for 1/0 gauge wire..... it needs to connect like 4 0 gauge wires.

I have a JL 500/5 which is 100 rms ch 1 & 2 and 25 rms ch 3 & 4 I am thinking of using it to run my bravox cs60cf active. My biggest question is what should i do about the rear should i amplify the rear speakers (bravox cx60cf) or run them off the deck. The reason I ask is because I also have a JL e4300 4 channel amp. I have heard some people say dont amp the rears and some say you should amp them and i don't know what to do yet any help would be cool.

Am wanting to get another bettery to help upgrade my electrical. Does anyone know if the special application Kinerik HC 2000 is the same as the regular HC 2000 because i can find those for a lot cheaper price than the regular ones? I think i read somewhere that this years regular model has higher amps rating than last years special applications model. How true is this? Thnaks in advance for the response.

Dave maybe you should sell the PG for this beast but any way here is the link to the page on their site: http://www.soundstream.com/sub/products_amps_xxx.html

well we built a wall, the amp is currently fairly far away form the subs, about 6 feet of speaker wire goes to each sub, we are currently using cheap 14 gauge speaker wire LOL, but we are pulling a 152.7@1800 watts clamped, my guess is we would gain quite a bit by changing out speaker wire, what would you guys recomend? there are 4 dd 1500 series 12" subs hooked up to a planet audio 3000 wired to half ohm in a wall. looking for the best speaker wire that will transfer the power most effectivly for the long 6 ft run. thanks, Anton Miller

I have been researching the Diamond amps. Should I go with the new D6 line or the discontinued D7's?

With two D1 ohm subs if wired in series for a 4 ohm load with two 1500rms 1ohm mono amps strapped would that give me a final load on the amps of 2ohms being there strapped? If wired in series/parallel for a 1 ohm load with two 1500rms 1ohm mono amps strapped would that give me a final load on the amps of .5ohm strapped? Also out of all the researching I've done regarding strapping, is it true that 2 strapped 1500rms 1ohm mono amps be like a 3k 2ohm amp? I posted this elsewhere also n I believe they answered wrong considering everything I find its double the power/ohm just wanna get another opinion in a better worded post

okay guys it sounds like a noob question which is probley is but im just trying to figure out what i am trying to see as a final impedence i have 2 woofers with .7 coils 1.) if i wire it in series/parallel does that mean i get my amps at .35 each and .7 total? or does each amp get .7 and 1.4 total? 2.) if i wire it in just series does that mean my amps each will see close to 1.4 ohm each? and 2.8 total? just getting lil confused on this any help please

Has any one used these. Good or bad?

So I just got two 12" daily Bl's and was wondering what type of amp to run them with. I have a stock electrical system on a 2001 Elantra and do not want to mess around with the electrical so I want to know what type of amp to run them with without having to upgrade. The subs are dual 1 ohm and I will be using a ported box. I also need a new head unit but i only want to spend $100-$250 on that. On the amp i'm open to spending up to $400. Thanks for your opinions/suggestions.

I currently have a P550MP (see sig) its a premier line, wma/mp3 capable, i believe 2.2V outputs (3 total) etc. etc. and was wondering if it would be worth it in SQ and features and just overall to spend the money to upgrade HU's? i would be buying the 860 used so i would be paying 200 ish...thanx for all the help...

i was @ Harbor Freight and saw an analog Volt meter that bosted different color LED's for $19.99 so i got a lil help from Alan Hall and well minus 1 smaller cup holder later... 3/4" Mdf wrapped in Blk Vinyl heres the installed pic off on with motor off on with motor running different colors not bad for a cheep fixx, waiting for Stinger to replace my digital volt meter. http://www.harborfreight.com/cpi/ctaf/disp...temnumber=98479

Haven't been here in a while guys Just wanted to know the advantages and disadvantages of running amplifiers at different loads. Nothing specific, in terms of amplifier brand, but just general advantages and disadvantages. Thanks.
