HO Alt/Yellow top

[02celica]

Will a High Output Alt coupled with a Optima Yellow top battery be good enough to handle (2) 10w7's with a 1000/1 and then all my compents and 2 ways also?

The shop says i should put in a 2nd batt but i dont wanna have to pull out my 1/0 that i JUST ran.

Thanks for input.

What is the HO Alt's rating? If its 175w at 4k rpm than you are fine. I would not recommend a second battery.

Actually a second battery can have a inverse effect and draw more current from your setup. Due to the load characteristics of the battery and depending on the wiring setup the second battery can/will play "tug of war " with the other battery for power.

Ask anyone with a 2 batteries. They are headaches when you have a short or not enough power is delivered.

In the end it really depends on the ho alt and the cables you ran, which will support your setup, hell a 4/8 would be plenty for what you have.

^I was told 1/0 by many shops due to the fact that my amps are rated at 80, 60, and another 60. They said that would be the best since its running from front of my car to rear and its pulling that much amperage.

and hows this HO Alt.

I'd hazard to guess that you'll be fine w/the HO & Yellowtop. You won't be pulling max current all the time. That alt. from Ace should be fine. A number of members have gotten those.

For 200A capacity... 1/O won't hurt... can probably get by w/2ga or parallel runs of 4ga. Its a pretty short run.

i agree dont do 2 batterys they are a headache its an on going battle for me to keep everything charged up enough

I bought that same ho alt from Ace Alt's a couple weeks ago. Installation was pretty simple and it's been working great. I'm glad I got it from Ace, because this place (http://www.highoutputalternator.com/) was quoting me $500+ for a ho alt also rated at 170A. :bang:

If you're gonna install it yourself and have some Q's, lemme know. :D

[2way]

^Yep... it should be mentioned that you need to upgrade the alternator wiring and fusing to handle the additional output.

[RekD0514]

The 2 batteries only really helps when you are not running the engine and sitting still. Try out that alternator.

[02celica]

Sorry to bring this up from the grave.. but should i get the ALT or the battery first? I was thinking the alt.. but i want to know for sure before i purchase anything!

[2way]

Depends on your initial needs.... if your existing batt is on its last legs... or you are starting to draw more current... do the batt 1st. If your current alt can't keep up w/your present demand... do the alt first. I would suspect that you currently have a decent batt.... so, I'd say do the alt.

I'm sorry, but I have to disagree. Unless you already have a deep cycle battery, I suggest you buy one and save your current battery for a backup. It will make a tremendous difference on your sound output and coupled with a 1.0 farad capacitor, it will save your electrical system (2 10w7s on a 1000 watt amp is a MAJOR power drain). It sounds to me like you'll be running your system while your car is off anyway. Definitely purchase the alternator, but battery is your initial concern.

[02celica]

I dont listen to my system with my car off.. im never in the car when its off.

But i mean i was thinking since i never listen to my system without my car on that the alt would be first because its supplying constant power when the car is on.. so the system would be really pulling off that right?

[2way]

^Yep... I stand w/my initial assessment - if your current batt is in good shape.... do the ALT first... it will supply the necessary current to run the system & prevent the batt from going flat. After that, a better batt will reduce the lag with the alt's regulator on bass punches.

[02celica]

What kind of "lag" is there?

[2way]

Same idea as adding a cap. The voltage regulator seeks to maintain a constant voltage. A bass punch will cause a momementary current surge/drop in voltage that the regulator will be unlikely to respond to in a sufficient time frame. Regulator sees voltage drop and commands ALT output to correspondingly rise. By the time that all happens... the punch/drop will probably have passed.

The ALT will carry your base current load and charge your battery, your cap & battery will carry your surges.

upgrade "the big three"! info here http://www.the12volt.com/installbay/forum_posts.asp?TID=73496&PN=1 caps are useless. a 2nd battery is an added drain on alternator while the car is runing. i do meca car audio competitions. i have hit 147 on a db meter with four 12"s (in a push pull box) and an old school mtx amp. no upgraded alternator just a optima red top and "the big three." there are alot of little things to do to increase db's.

[02celica]

^Not looking to increase DB's.. should read the thread before you reply.

And ive done big 3 upgrade and added a 3 Farad Cap. Now going to finish on the alt/battery.

[NFS-Ed]

Get a red top - Yellow tops always die. I know I sell them at my job.

[DatDudeDEnd]

simply adding a high current alternator WILL NOT solve your power problems. unless you have the correct type of battery with it. In my opinion, a good definition of "sufficient battery capacity" is when your fully charged battery (or batteries) can perfectly maintain the electrical system loan (all vehicle electrical components which share the battery, or batteries, with your stereo components), without any additional charging input, for at least 30 minutes (or longer -- based on how long you typically operate the audio system when the car is not traveling, more or less continuously. Some alternators do not produce their maximum output until engine speeds are well above idle -- typically 2,500-3,000 rpm on the average passenger vehicle they may produce very little (or even no) power at idle speeds. In stop and go traffic. So its a good thing that you dont listen to your system when the car is turned of.

Also you must know the peak, minimum, and average power requirements of your stereo system. Without this data you simply cannot properly determine how much alternator capacity that you require.

For example, if your audio system demands an average of 100A, and if your basic vehicle electrical load is, say, 64A (typically 80% of your stock vehicle alternator's rated output), and you have installed a 200AH battery bank, you will need an alternator that can supply at least 300A.

[02celica]

Get a red top - Yellow tops always die. I know I sell them at my job.

Yeh but if the red top dies and optima knows you have a system the warranty goes bye bye.

and guys im not running stock battery as it is.. and i know all the info i need to about my system in order to make a good choice. I'm not an idiot when it comes to this stuff.. and i like to think im far from it. The alt i ordered puts out 80amps at idle.. and 175 at 1200 rpms. and my system pulls like 140A right now max. with rear speaker 200A. Plus my current batt has like 500A? or something.

[chillan420]

how would optima know what the hell you do? :whogives:
Do you think your "system" reguires these upgrades or are you just ignorant and have money to waste? you came here and asked for "input" dont bash the people here trying to give you advice and help you out. why would you waste money on parts you can not benefit from?
Plus my current batt has like 500A? or something "or something"???? HAHAHAH WTF I'm not an idiot when it comes to this stuff.. and i like to think im far from it
good thing your educated. go ahead keep thinking for yourself seems like your better off than asking for "input" on this forum.

I want some of whatever you smoke on a regular basis.

02celica will require a battery other than a wet cell type... .i.e. red top. He will probably need one with a faster recovery time etc. such as a deep cycle, SLA, or gel cell.

I like how you talk like i dont have something. maybe you should look up my other threads and actually see my system. Maybe then you will see that my car really NEEDS these.

[chillan420]

i have searched your posts and i see your father has done alot of work on your car.
i have a little something also my 2 1000 watt mtx amps, a 81000d and 1004 they can pull up too 300 amps of current. i will redoing my entire trunk setup very soon but here is a bad teaser pic of what i ran before. JL audio is great quality but is nothing special just way overpriced.

HAHAHAHAH WTF. Why are you running your mouth? Youre the one with 4 12's putting out 147db. Its possible to be hitting 147db + with around 1200w. Push-pull is for looks, nothing else. Looking at your picture, I see wires all over the place. Doesnt look very clean to me. Have a shot of an ammeter to prove youre pulling 300A? The stock alt puts out ~80A if memory serves me right, and I highly doubt youre pulling 300A off a stock alt and a red top.

What kind of "db meter" were you metered with? Why are you using two different mono's? How do you have them set so that they have the same output? Then you go on to say JL is nothing special... I guess thats why youre using Audiobahn? And wait a minute... If caps are so useless, why do you have one?


02celica, the shop thats trying to sell you a second battery is trying to rip you off. A HO Alt and Yellow Top are more than sufficient for what you need. Even a HO Alt and Red Top would do very well. Personally I would get the battery first, then the alt, if you plan on getting the alt at all.

[02celica]

I actually decided after talking to RekD0514 about it all that ill just get the Alt first because i already have a aftermarket battery. So i ordered the alt last night off ebay. Should be installed by this weekend if i get it.

[SpikedCola]

^^ Post install pictures and/or a how-to guide. Havent seen one done yet. Oh and be sure your dad does it for you, so you can take the pictures ;)

[RekD0514]

I wonder if you need a different sized belt for that sucker too..?

[02celica]

I for sure will.. ya know because my dad does all the work on my car for me instead of me. ;)

[SpikedCola]

Cant see you needing a different belt, the pulley should be in the exact same location and be the same size.

[02celica]

^I dont think i will need one either because its a direct replacement.. and the alt is just a rebuilt stock one.

[chillan420]

i thought this forum was created to help people and share information. i dont claim to know everything. im not here to talk ****. i dont post things that i am unsure of or havent personaly experienced. im not here to tell people what they should do or not do. to everyone there own. i am not here to hate or get **** from people whom i am trying to offer my experience and help. i wish i had experienced friendly people to give me advice when i was 18 and i was building my first system seen in my pic. 02celica dont disreguard valuable information people on this site are offering. you should be thinking them for ther time and effort in helping you weather or not you like it or agree. good luck with your alt install i hope it is "good enough" like your original post states. with this forum you have the potential to be better than "good enough".

[SpikedCola]

"or something"???? HAHAHAH WTF
good thing your educated.

Its things like that that made me go after you. If you dont say things like that, or be polite about how you say things, no one will give you sh*t.

[chillan420]

Its things like that that made me go after you. If you dont say things like that, or be polite

its funny how ignorant people can be so arrogant...
you had no insight on this post until you felt the need to disect and trash my post. Polite ?? you dont know me or anything about me. you pass judgement and question me like im talking s*hit when thats what you came her to post. your a hypocrite with a lot of time on your hands to "go after me". must you overcompensate for something? I can post here and share me knowledge and experiences here just like everyone else without proving anything to you o holy jesus of nc.org "spikedcola audiophile Extraordinaire"

[SpikedCola]

Yeah, you got me.
