A couple questions: I know capacitors store power or whatever so no juice is sucked from the battery, but what is a farad? how can you measure it in watts? or how can you measure watts in farads? The reason i ask is that i need capacitors, but im not sure how many. Another thing, is adding another battery harmful if you do it the right way? are there any concequences for doing so?(bad starts, etc.) oh, and another thing......why does everyone ALWAYS hate on sony?...lol ------------- "It don't matter if you win by an inch or a mile...winning's winning

Just cuirous, why do you think you need capacitors? Generally a high output alternator is what people need then they think they need a cap. The general rule for caps is 1 farad per 1000 watts RMS. The major benefit of another battery is if you play your system a lot with the car off. If it is installed right, there is no harm. Personally, I don't hate sony. But I would't buy it either. They make good home theater stuff. When it comes to car audio you can get better equipment for the same amount of money.

capacitance (Farads) is completely different from average power (Watts) and do not convert. I think the old rule of thumb is 1 Farad for each 1000 Watts..

A farad would be a unit of electrical storage. Or an exact definition- "Farad - The basic unit of capacitance. A capacitor has a value of one farad when it can store one coulomb of charge with one volt across it." This was taken from the glossary section of the site. And as far as sony, I personally haven't seen anything that I like except for a little 4 inch screen I had like 5 years ago, that is the only thing I had ever liked sony.

well, eventually, i'm hoping to hook up 3, 1000 watt xplod(i know, i know) amps (xm-2165 i believe). i might even hook up the little tiny 100 watt crap amps i have juss for my 6 1/2"s. im not sure if juss the alternator will work. i plan on replacing the alternator with a better one soon, but again, i dont know if that will be enough. thats why i was asking about the battery also. i was wondering if adding a battery would help in any way. everything thats going in my van is going to be sony(h/u, amps, subs--------4 10" p5 series & 2 12" p5 series), and i juss dont understand why everyone dislikes sony so much. the only thing i buy now is sony because the setup i have(really nothing special, juss some diy stuff) sounds really nice. no one can believe it when i roll up in my beat van and blast em with only 2 10" p5s. it juss seems to me that no one gives sony a fair shot.

ya, get a alt. in the long run you will be happyer,,,especially with that kind of electrical usage. You will need at least a 150 amp alt to keep the system in the 14 volt range. And sony is the most in-efficient amps i have ever seen,,,so your gona need that extra juice.

I started reading this thread and when i got to the post on wanting to put in 3 1000 watt amps in 2f2f4evva vehicle i sarted to laugh!!!! that amp he is talking about only puts out 400 watts bridged!!!! HAHAHA I work at circuit city and we sell those things for 200 brand new!!! My store uses them on our rear speakers 'cause that is all they are powerful enough for!!!! One of the reasons everyone always hates on sony car audio is because they ALWAYS over-rate and underpower their stuff!!! (not to mention their sq aint so good) when you get the chance, go to circuit city and have them play a pair of sony 6.5 and then have them play the infinty 6.5 speakers (only $30 more) and see the difference!!!!! (I do it every day) Please don't be a poser and use all sony.... a deck... ok i guess, but no speakers or amps! ------------- Don't Sing IT... Just Bring IT!!!!

Hey silversteve, I really don't care where you work, with an attitude like that you wouldn't be working there long if I was the manager, maybe it's all the customer can afford? I don't sell Sony but after reading your reply I would be more than happy to go out and find the equipment for him. Sure Sony doesn't make some of the best audio equipment, it doesn't mean you need to slam it the way you have and piss off a customer who works hard to save for equipment and Sony may be all they can afford, learn some tact my friend, if you want to excel in this industry, you need it. Did you know that Sony used to build some really good car audio equipment?

I remember when I was starting out in this stuff and could barely afford anything during my part time job in high school. I got some of the cheapest bs stuff I could find to set up a system and still amazed quite a few people. This stuff was even ranked below Sony. Some of the stuff I still recommend just because it's cheap and gets the job done. My stance on things is that it's the install that plays the biggest impact on how your system ranks. Not to mentioned I learned a lot from working with crumby equipment like how to dodge noise and tune things to perfection. As far as equipment goes I just recommend paying the most attention to your head unit.

basically, i don't hate on sony,,,it is way better than factory. Sony is something you sell to customers with blown factory speakers and just wana hear there tunes again. The infinity/alpine and such is for the people that have made the step with the sony,,,and decided they want more , so they then get the good stuff. I just wouldn't make a complete sony system,,i would suggest to the customer that ha/she would be better off in the long run to go for the higher quality product becuase it will be able to keep up with future upgrades. my store sells soundstorm and alpine,,,and believe it or not, we sell more alpine than the sound storm just by giving them the "in the future" speach, , you can get most customers to step up the sale by $200-$500 by just doing that.......Yes soundstorm sux, but its what somepeople are looking for.

OK,OK i was a waaaayyy too harsh, i'm sorry! (I was in a crappy mood and i took it out in the wrong place) I still don't care for sony much but it is certainly better than factory. Yes, i know sony used to make quite nice equipment in the past. Unfortunately their quality has dwindled since which is quite unfortunate. I know ccity is by far not the best place to get equipment but it is a great place to help newbies go in the right direction as far as quality. as for 2f2f something (sorry, don't remember your full name) i am sorry for being so harsh... i personally don't recommend a full sony system... most of the ones that i have heard tend to sound kinda flat and tinny... and that sony cdx-c90 is a wonderful deck i do like the high end sony decks(forgot to put that in earlier) Please everyone accept my appology and my thoughtlessness in this matter... I promise not to do that again. Also 2f2f, if you are looking at sony only, then look at their higher line of equipment.. it may cost more, but it is worth it. But if you still want those amps, then they are going for 169 right now. (Pretty good price i think) And again everyone, i'm very sorry. ------------- Don't Sing IT... Just Bring IT!!!!

Oh, i almost forgot to add... Those sony systems that i have heard have still been quite loud and the people who did them were quite happy with em... Also no one has the best and no one has the worst system, cause it's all a matter of what YOU think. Again, and no i can't say this enough, i am sorry 2f2f4evvr for talking down i'm sure your system will rock once it is all done no matter what. You really didn't deserve what i said. I was wrong.. The owner's opinion is the only one that matters if it's for fun and the db meter is the only thing that matters in spl. ------------- Don't Sing IT... Just Bring IT!!!!

Anyways, back the original question, I've always gone by the good ole rule of 1 farad per 500 watts. It's always seemed to work good anyways. Of course if a guy is getting up to 1000 to 1500 watts system power (RMS of course) , he better be looking at a new alternator and battery.

tuneman is right. I have always gone by the 1000 per farad rule but if you start to need more than one or two farads you should look else where to beef things up. I would recommend the alternator. I kept putting it off with my first install and I smoked three of the stock ones in about a year and a half. I know the good ones aren't cheap, but its better to shell it out right away than to continuously replace the cheaper ones.

I personally use a 1 farad for my 800 watts and it works perfectly while driving, absolutely no flicker (unless my truck is turned off or just idling. Although a new beefier alternator and battery would probably get rid of that. ------------- Don't Sing IT... Just Bring IT!!!!
