Gold Member Username: B101Queen City, NC USA Post Number: 1786 Registered: Sep-05 | 200-250A SHOULD DO IT; but get the biggest u can afford! |
|
Bronze Member Username: BuckshotPost Number: 90 Registered: Nov-05 | yes get bigger than u need incase you wanna add extras or upgrade |
|
Silver Member Username: Jprix82Post Number: 368 Registered: Jan-06 | Well the biggest i can get is a 300amp from excessive amperage not sure on the price yet tho. |
|
Gold Member Username: B101Queen City, NC USA Post Number: 1806 Registered: Sep-05 | Nathan at excessive amperage is good! get 300, u wont ever have to worry about upgrading, prob going to be 1dollar per amp. so about 300 plus a lil more. |
|
Silver Member Username: Jprix82Post Number: 371 Registered: Jan-06 | Thats what i want, to not have to worry about upgrading again if it is in the 300 range ill be hella happy.what is his warranty? |
|
Gold Member Username: B101Queen City, NC USA Post Number: 1814 Registered: Sep-05 | talk with him, i think its 3mnths. he will explain alot better... its a good product, i havent had any issues with my 200amp in the large casing... |
|
Silver Member Username: Jprix82Post Number: 373 Registered: Jan-06 | What you think a 300amp for him will do at idle? |
|
Gold Member Username: B101Queen City, NC USA Post Number: 1828 Registered: Sep-05 | atleast 220 @ idle, u will have to ask him though.. cause it highly has to do with the casing.. large or small... large casing will cost more $$$ |
|
Silver Member Username: Jprix82Post Number: 375 Registered: Jan-06 | Im kinda a litte stuck on how alts work if a 225amp alt does 100amp at idle that means with the car idleling right?and it will do the 225amps at higher RPMs ? |
|
Bronze Member Username: BuckshotPost Number: 93 Registered: Nov-05 | i meant upgrading his system not the alt |

Joseph correct, what its rated for @ idle, is the current it will put out @ idle. so if your car idles at 800RPM, u will get 100amps.... now if u hit the gas peddle to 2000RPM, u will get full output of 225amps, if thats what the alt is rated at! so the more current @ idle is better, and important! I like to bass at traffic lights, and when Im stoped and car idleing, u know.... |

Silver Member Username: Jprix82Post Number: 377 Registered: Jan-06 | BOOOOOOOOOOOOOOOOOOOOOMMMMMMMMMM right |
|
Gold Member Username: B101Queen City, NC USA Post Number: 1837 Registered: Sep-05 | ^^^ YEPP  its alot louder in person, LOL u also feel it in person too.... LOL |
|
Silver Member Username: Jprix82Post Number: 379 Registered: Jan-06 | ^^LOL^^ When people says their alt puts out 14.4v or something like that what does that mean? |
|
Gold Member Username: TheelfkeeperStockbridge, GA USA Post Number: 1395 Registered: Feb-05 | 14.4 is the voltage level, usually at the battery, that the car sits at. typically its about 13.8 at idle and 14.4 at 1500-2000 rpms and up. it iwll vary though depending on the voltage regulator on the alternator. |

Silver Member Username: Jprix82Post Number: 387 Registered: Jan-06 | On the big 3 upgrade the engine to chassis upgrade, do you find a bolt on the motor and then ground it to any metal part of the body? |
|
Gold Member Username: B101Queen City, NC USA Post Number: 1899 Registered: Sep-05 | find a bolt on the motor, then grd it to the batt neg!! find a bolt on the chassis or "metal part of the body" then grd it to the batt neg!! find pos back of alt, then add it to batt POS!!! ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ BIG 3 |
|
Silver Member Username: Jprix82Post Number: 389 Registered: Jan-06 | Is yhat how you did it B? So all the grounds come from the negative battery post? |
|
Gold Member Username: B101Queen City, NC USA Post Number: 1922 Registered: Sep-05 | nah my big 3 is way more complicated man... just look at my pictures... but u dont need to do what I did. lol |
|
Silver Member Username: Jprix82Post Number: 390 Registered: Jan-06 | but that method will still work right |
|
Silver Member Username: Goose5714Post Number: 367 Registered: Feb-06 | I thought big three was 1. bat pos to alt pos 2. bat neg to chasis 3. chasis to engine block (not engine block to batt) Heres my justification lol http://www.caraudio.com/forum/showthread.php?t=124175 Everyone there says its that...correct me if i'm/their wrong. This'll probably be a good thing to know when i go to do it in a week lol. |
|
Gold Member Username: B101Queen City, NC USA Post Number: 1939 Registered: Sep-05 | both are the same man... LOL  this is what I said above..... find a bolt on the motor, then grd it to the batt neg!! find a bolt on the chassis or "metal part of the body" then grd it to the batt neg!! find pos back of alt, then add it to batt POS!!! JOSH #3 & #2 are the same points.. both still GRND to NEG batt man! |
|
Silver Member Username: Jprix82Post Number: 399 Registered: Jan-06 | Hey B, Would it be ok if i run 2/0 ga wire for my Big 3 upgrade and 1/0 ga wore for my amps or should i run 2/0 ga to my amps to equal up with the big 3? |
|
Gold Member Username: B101Queen City, NC USA Post Number: 1946 Registered: Sep-05 | it all depends on how much stuff you gonna have in the back! you should be fine doing that... but the bigger wires for the big 3 is best!! |

Silver Member Username: Safe_crackerChicago, IL US Post Number: 505 Registered: Jan-06 | Large casing or small it will not do 220A at idle. I ordered a large casing 300A amputator (Iraggi) Alt and with the smallest pulley it will run 155A at 750 rpm idle, 300A max. My alt cost me $485, $35 for a special bracket can't wait to get it in. B in your profile I am still trying to figure out how your 200A alt is running 200A @ idle, lol. You must be running an old Quadrajunk carburetor with a bad choke pull-off, lol...(Hi idle)  Polo.. |
|
Gold Member Username: B101Queen City, NC USA Post Number: 1965 Registered: Sep-05 | umm, Nathan got me up to 200a @ idle. LOL the series 2 alternators look alot smaller to me...... my series 1 factory alt was big, but this new large case is huge!! the pictures show it NO justice.. Its way large than my factory! It took Nathan sometime, he also had me measure alot of stuff first, and take plenty plenty pictures... The fuel injection idles @ about 900RPMs, if I BASS at idle, the RPM goes up to 1000RPM by itself.. It also has a tiny pulley, so it spins fast as fu(k!!! I also paid less than 300$ With the car runing, & my hand anywhere ova the engine, i can feel madd breeze coming from the alternator!! It really blows, and keeps itself cool too. |
|
Gold Member Username: B101Queen City, NC USA Post Number: 1966 Registered: Sep-05 | I had to explain to him, my car is a LOW RPM engine!! my redline is like 5000RPM... LOL I can do 60 MPH with the rpms @ 1K in OD !!! lol @ 80mph she is @ 2.25 rpms... LOL I made sure he understood that!!!!  |
|
Silver Member Username: Safe_crackerChicago, IL US Post Number: 508 Registered: Jan-06 | Ya, my GTP is the same way I actuall kick it into 3rd at times to charge the system on the e-way, go figure, lol. I have an on-board computer and found in OD regular driving I have lost .60 mpg from bumping (mildly) on the way to work! Better put some gas in that b!tch, your sucking fumes, lol...Polo. |
|
Gold Member Username: B101Queen City, NC USA Post Number: 1968 Registered: Sep-05 | lol, I drive that thing like a honda accord or civic.. hahaha. with gas prices so freakin high, she stays about 1/4 tank these days. lol... I remember when $20 filled her up, now that wont put her on half!! |
|
Silver Member Username: Jprix82Post Number: 409 Registered: Jan-06 | The gas here is $2.47 a gallon for unleaded what is it where you live? |
|
Gold Member Username: B101Queen City, NC USA Post Number: 1985 Registered: Sep-05 | i just passed gas station, gas 2.54!! <<<Regular 2.74 was Premium!!! |
|
Silver Member Username: Jprix82Post Number: 422 Registered: Jan-06 | Yeah gas is CRAZY. B how many watts RMS you think i could run off a 300amp alternater? |
|
Gold Member Username: B101Queen City, NC USA Post Number: 1993 Registered: Sep-05 | u will have your butt covered for a long time.. lol pretty much ALOT!!! all u need is a yellowtop if u still upgrade some more.. |
|
Silver Member Username: Jprix82Post Number: 424 Registered: Jan-06 | Good cuz in the future i plan on running 2 MT 15s off 2000+w each so i was hopeing i would be ok cuz i have no room to run dual alt. Would 1 Redtop under the hood and 1 Yellowtop in the back be enough to run that kind of power? |
|
Gold Member Username: B101Queen City, NC USA Post Number: 1995 Registered: Sep-05 | sure, but 1 yellow under the hood and 1 yellow in the back will be better! |
|
Silver Member Username: Jprix82Post Number: 425 Registered: Jan-06 | I thought Redtops are starting batts cuz of their CCAs and Yellowtops are for sounds cuz their deepcycles? |
|
Silver Member Username: Safe_crackerChicago, IL US Post Number: 509 Registered: Jan-06 | Ya but unless you are using an isolator, the trunk Yellow top will rob power from the Red top starting battery which does not have as many recoveries as the yellows so it will die first. Two yellow will last a long time as they will be matched. Polo.. |
|
Silver Member Username: Jprix82Post Number: 426 Registered: Jan-06 | So i could run 2 yellowtops without an isolator and ill be fine? |
|

Silver Member Username: Jprix82Post Number: 429 Registered: Jan-06 | bump |
|
Gold Member Username: B101Queen City, NC USA Post Number: 2004 Registered: Sep-05 | Yes, no isolator needed! And yes, POLO is exactly correct! |
|
Silver Member Username: Jprix82Post Number: 432 Registered: Jan-06 | BTW just curious how would someone install a isolator? |
