Should I stick a fuse inline between my cap and each amp? I'm gonna be running the xtant 202m and 1001x neither of which have onboard fuses.

I'll have one 150a under the hood inline near the battery, but, can't the cap shoot out jolts of power that the amp can't handle just like the alt. can?


Help!

You don't need a fuse between the cap and the amps. Besides, the cap has to be as close to the amp as possible.

Will it hurt not to have the extra fuses?

not really a lot of people have 1 under their hood and in their trunk even if their amp has an onboard fuse.......... i do..........

a cap only puts out the power if it is needed it doesnt just do it on its own free will only when its called upon for it but do u have the charging system fo a cap otherwise a cap will never get charged in your system and will just keep on discharging and it wont affect anything

It's not required when you have an onboard fuse and I know that already. I have dealt with amps that have onboard fuses for a long time, with the exception of my old x603 xtant which fried, and now I'm about to remove my current setup and replace it with 2 xtant amps that don't have onboard fuses.

Don't need to explain anything else to me as I probably already know it :-)

Fuse it, or not? That's my question.

Thanks :-)

unless your never wrong and always do everything correctly like everyone else in the world (right?)... i would put one in. its not REQUIRED, but it can help in the event of an unknown accident.

a fuse is there to protect. if your going to spend hundreds of dollars on the amp, why not spend a couple bucks to protect it with a simple fuse. its not going to hurt anything. its just to be on the safe side. if you look on xtants website for the manual, it states you MAY add a 120A fuse near the amp for safety, but the one near the battery is a MUST.

Thanks :-)

Just needed someone to justify me spending more money onother fuse holder and fuses lol.

I always triple check my wiring before I hook it up, so I'm rarely wrong with power/ground. There was one occasion where I accidently hooked - to + on a pioneer sub, but I think that was lack of care because I didn't much want the sub it was all I had lying around and couldnt afford a better one lol.

Good read.

After studying a little history on large 1 Farad capacitors in car audio, you'd be amazed that they even sell at all. How useful are they? What do they really do? Will a Cap 'improve' my sound quality? Will it Prevent my lights from dimming? Will it audibly affect my audio system in any way?

Before you get the truth to any of the above questions, chances are, you've probably spent $100 or more on one of these devices. However, let's study a little history regarding this issue.

A long time ago, in a land far away, 2 elves...Ok, Richard Clark & Wayne Harris (Carsound magazine and the inventor of DB Drag, respectively) separately came up with a solution to preventing their lights from dimming.

WHO WERE THESE GUYZ?

As you may know, Richard Clark is one of the founders of autosound2000 Tech Briefs, Carsound magazine, and a published author of the industry of mobile electronics. In SQ competitions, he posted a record of 1234 1st place finishes, and only ended up NOT 1st in his first event. I've heard that he had minor system problems, but judging by his record, he must have corrected it. (evidently, he needed a Capacitor )

Wayne Harris was previously a leader at Rockford Fosgate in their development. Later, in his free time, he created the organization we call DB DRAG. Wayne was the first SQ World Champion from the organization we know as IASCA (International AutoSound Challenge Association).

Both of these gurus are both legends, and considered the leading experts in the field. During their competition days, both guyz came up with a way to assist in the prevention of voltage drops. In SQ competitions, the look of your system is actually more important than the sound, and having your lights NOT dim under high playing levels is a competitive advantage.

As you may know, amplifiers are made up a bank of little capacitors, resistors, etc. What has been common engineering knowledge is that capacitors store energy, and more or bigger ones assist in balancing the power supply.

Wayne came up with the idea of putting several dozen 'little' (approx 100uF) capacitors on a circuit board to 'extend' the power supplies storage. At about the same time, or shortly afterward, Richard came up with the idea of one huge mondo capacitor (I believe it was 800,000uF or 0.8F) to do the job.

Eventually, Richard won. The large cylindrical tubes won over the complicated 48 caps strapped to a circuit board. However, what did this really accomplish? Let's start here:

WHAT IS A CAPACITOR?

Basically, capacitors are an energy storage device. Large, 1 Farad or more
capacitors store energy (electrons) between their plates. Capacitors differ
from batteries because batteries store energy in the form of chemical
energy--and rely on acid and lead plates, as the place of storage. For a more detailed
description of a capacitor, go here:

http://www.carsound.com/ubb/Archives...-1-000307.html

Phoenix Gold's marketing guru had just posted information on how their Powercore (basically the Alumapro CAP15 in a Phoenix shell) had both stabilized their voltage and improved the sound quality. Richard called him on it (all in another post) and the marketing geek was unable to quantify any of the conditions that resulted in the voltage being HELD at 14.2V and the 'improved' sound quality.

Please do not read every stinking post as valid. There are a lot of people that have had the efficacy of capacitors inbred to their minds, and were not (and still not) convinced in the futility of a 1 Farad storage device.

In a final note, Richard relayed a quote regarding battcaps ( www.battcap.net ) as, "..The audio industry is the only place i know of where you can publish specs that show your product is useless and still be able to sell them------and whats worse is that technically ignorant people will argue against the math!!!!!!!..............RC.." when referring to the product. This also relates to most digital readout capacitors, and I wish my Archie Bunker skills could have said it better myself.

Thank you renegade. That was the best read on capacitors I have seen.

I don't understand why you've posted this in my thread? I would think everyone, including myself, on this forum would already know this.. or at least the majority.

This thread was intended to aid in the decision of buying another set of fuse holders for near the amp :-)
