whats up yall. in my system i have us amps 400, esx q404, two ssd12's, a duralast battery upfront and an optima red top in back. for fuse i only have the one in between the two batteries and it is 80a. thats the only one the local car shop had left at the time of install. my question is should i go ahead and order a bigger fuse? does it really matter? and should i have another fuse somewhere in my setup? the esx is internally fused and the us amps has very good internal protection. anybody with thoughts on this?

Im sorry to waste your guy's time with this one.. im about 99.99% of the answer but I have to ask. I got my order from knukonceptz yesterday, i had ordered 2 of their ANL fuse holders with 2 250A fuses. They sent me 300A fuses. clearly their mistake after checking the confirmation email. Ive been told to fuse to your wire. the wire i have is the KLMX KnuKonceptz wire which states loads up to 250A .. these 2 fuses were meant to go in between 2 batteries (kinetik hc2000 and hc1800) I have the proper fuses for everything else just these 2 that are a little higher than i asked for. Do i gotta go spend the $10 or so and get the right fuses? or even worse wait for knu to send m…

I know to add up all my amps fuses and the total is my in-line fuse size. My question is about fusing at the db block. I've read in a previous thread on here to fuse under never over( i.e. 180A = 150A). I have an amp (US Amps USA-150) that requires fusing at 75A. It has 2 inputs for positive and 2 inputs for the ground wires. Can I use a 40A + 30A = 70A fuse in my db block or will it affect anything being different sizes and under the fuse rating? Thanks and have a Happy New Year!

ive read people saying to use the fuse rating to get a idea of how much rms power a amp will give you, can someone explain this to me? is there a formula to multiply or something to get an idea of this?

whats the optimal fuse size for a run of 0 guage to run a bc3500?

A quick question I am planing to buy this wire from knuconcepts when it asks me to choose fuse size what do i pick right now i am running a dc l4 12 with an aq1200d. i want to upgrade in the near future with 2-3k watts:) the question is it fine if i get the 300 amp fuse? http://www.knukonceptz.com/productDetail.cfm?prodID=KFX-PK0

what type of fuse should i use for the amp to battery power wire (in an inline fuse holder from knuknoceptz). if this helps...the wire is 1/0 gauge, the amp is an saz 1500d, sub is going to be a bl15.

Hi Just want to know a few things that remain unclear to me. Since I do not plan on running 18s anymore, will only run 2 12s (XCON, ZCONS or maybe BTLs) with probably a Sundown 3500D. Should I bother using 2/0 gauge for power and ground? I was about to purchase Kolossus Fleks 0 ($100) kit but just want to make sure I wont be in the "border line" when it comes to powering my amp. Also, will the Kolossus Fleks 0 handle a Sundown 4500D? Just in case if I decide to upgrade to that in the future. Im reading here http://www.bcae1.com/fuses.htm that 0 gauge only handles a fuse up to 325 amps. That means with a voltage of 12.6 you get 4095 watts. Thats 500 watts short of the 4500…

what is the advisable length of cable from battery to fuseholder for big three thank you

i am ordering knukonceptz 1/0 and im getting my fuses, what size should i get my fuses, i am running 2 from batt to powermaster 2400 and one from powermaster to amp.

Hey everyone i am new to car audio and am planning on doing a big setup. I was planning on getting a 250 amp alt with 2 yellow tops powering 2 audio q 2200 connected with 2 12 inch fi btls. My question is that do i need fuses? If so how big do the fuses have to be? How do i know? Where do i need a fuse the most? THANKS

Ive had a sundown sae 1200 v2 for going on 4 years now. Its been ran in two systems/cars both at 1 ohm. I installed it those two times set it and left it(set it differently). Been going strong until today. My car is a Buick lesabre with a stock 130a alt. My battery is under backseat and power n ground are ran from battery to amp; literally 2-3 ft long runs. My voltage has always been decent; mid 13s is about the lowest I see on hard drops. Today on my way home from work beating all the way here; 15-20 minutes. Right when I pulled into town my bass stopped.upon inspection all 5 30a fuses in the amo popped, the 120a fuse in between the battery and amp did not. All power and…

After my friend pulled his equipment out to get to his spare tire, he replaced it, but could not get the fuses to stop blowing. The way the story has been told to me, he has hooked everything back up the way it is supposed to be, started it, blew the fuses, bought new fuses, blew those, too. What am I missing here? Or what isn't he telling me? Anyone have a solution?

It was brought up in another topic I have, but they said they could get an 80 amp fuse to hold on a 3500 watt burp. I plan on competing in meca and knowing how this is done would be vital info to me. Let me know how its done.

So lets say I have the potential to draw 700amps with my system, If I have 1 battery under the hood and 3 more in the trunk, a run of 3/0AWG wire front to back, how do I fuse it? Last time I checked the largest ANL fuse was 300AMP How do you guys with monster systems do it? other than multiple runs of power wire.

This May sound simple to some but wanted some clarification. I am installing two batteries in my trunk. How they will have to be installed will require me to put about a five foot piece of wire between the positive connections. I will be fusing before first battery where it entered trunk location and fusing after second battery before amp connection. My question is should I install fusing after the first battery and then install a second fuse before it connects to the second battery or will one fuse between them be sufficient?

ive been looking for a decent amp and i ran across some forums sayin that the fusion 4000's are good amps, so how are the others? or is the 4000 the only decent one? im lookin at the 3000 for $228...

is the power plant series any good or are they overrated?

Nevermind

I really hope somebody out there can help me. I have a Fusion amp(FP-1000) I also have a remote bass control for the amp. Which is a little box that goes up front with you, giving you the feature to be able to control the gain on the amp. It is connected to the amp by a telephone like plug and cord. Here is the picture of it. http://www.fusioncaraudio.com/products.php...p;product_id=97 I am not sure if they let you post links on here, sorry if you can't see or read the link. I went back to the shop that installed the audio setup in my car. He feels really bad for the bass control that I have now stopped working. He contacted Fusion to get me a new one which fusion says t…

did some digging and this is what I have found so far.. a review on one of them from australia vs a pair of D3s and pair of Crossfire 4000Ds, link below: Surfboard

Okay guys, I'm in a bit of a pickle here. I will be buying an 18" BTL any day now, I'm going to run it with a Sundown SAZ3000.1, at 2 ohms for daily driving and 1 ohm for comps and such, I will back it up with a Kinetik HC1400, and 2 HC1800's, I will also do my Big 3 in 1/0 gauge, my problem is my alternator, it is a stock 90A, I took it in to a shop today to see if they could rewind it and get more juice out of it and they said they couldn't do anything for it, but I talked to Nathan Pedicord from Excessive Amperage about a 225A that would fit. Why am I unable to get it rewound or built up? Do I even need it? Or will the Kinetiks be fine. Any input would be great, thank…

I got my box design, I got the sub I want in mind. (Fi BTL 15''), I got the Big 3 finished. Getting a free yellow top optima battery. In the works of a 200amp alternator. Will a 200amp alternator run a SAZ-3000D amp with/without ease? I want to make sure that this setup will not stress my cars electrical system if I have everything that I listed above. I would like to make this my daily system and enter small competitions. Comments much appreciated. Thanks, -Curt

ive never even helped installing a security system before...led alone one this complicated. I have a pheonix digital (i know) PD-175. The only major problems i could find with this was the rem starter. and i have a manual so i dont give a rats ass about that chit. Now i have manual locks. so it obviously isnt going to be controlling my locks. however its talking about the door pin trigger? WTF? im geussing this is the wire that knows when a door has been opened to send that current to a relay to turn on the dome light. there was a thing on here about getting a CD instalation help guide thing and i asked but never got one. oh well. maybe you guys can help me. im looki…

OK, so if I don't have it completely backwards, I understand that the higher the preout voltage, the lower the gain can/should be set because the amp doesn't have to be as sensitive of the incoming signal - so the amp can put out full power with the lower gain. My question is since the gain isn't set as high, is the amp drawing less current because of it? Or is it drawing the same amount of current as a signal with a lower preout voltage and higher gain setting? Just curious.
