I own a 2003 sunfire which currently has a 105amp alternator. I was looking to run about 1300rms off it, but I know the alternator isn't big enough. The problem I'm having is that I can't find anyone who builds a high output alternator for my car, and I looked into getting it rebuilt, but I can't do that either. I don't know what to do. Are there any specialists for problems like this, or am I screwed?

hi ok right now i have my 2 hifonics brz2400's hooked up daisy chained... 1 set of rcas from the cd player to the input... then another set from the output to the input of the other amp... then same way with the remote... now i know you can link/strap these amps together... i was wondering will it make a difference if i decide to strap them together instead of daisy chaining them... will it give it more power or just be the same ??

Ok so I installed my Stinger voltmeter last week and tuned it or whatever with my multimeter and it works perfect,.. but now that I can watch my voltage.. it is weird. Sometimes when I am driving it goes below 12v.. this is even if my head-unit is off, no windsheild wipers, no headlights no ac.. nothing on just driving and it randomly went to like 11.6 even.. I have figured out my "normal" voltage when driving is usually 12.5-12.7v... like that's what it stays at most of the time.. but when im driving I notice it is randomly at like 11.9 then later its like 11.6 and its for like 5-10 mins sometimes and then sometimes it goes back to like 12.2 or 12.5 and just fluctuates a…

so mostly everyone knows about clipping, when the music gets turned up and it hits a bass note, starts to play it then quickly drops off. well i've been having this problem ever since i got my new setup and i've read the how to set the gain of an amp thread, done it. no change and i've tested the impedance of my vioce coils and they're correct, dual 1s i've tested the ohms on the output of my amp and it's reading 2 flat which is what it's supposed to be i've re wired my sub to the amp and checked my rca's but it still clips when it gets turned up. any other suggestions, please?

so i have decided on the speaker for my new setup, it will be an ssa xcon 18 in a sealed enclosure, but now i need to find an amp to run it. i have been doing a lot of research and have come to see what kind of input i can get from people who may have used this equipment before to steer me in the right direction. i have a limit of about 300 for the amp, i realize this will not get me the best amp to run the sub, but i am ok with this. i have composed a list of the amps within my price and power range, but am open to all suggestions and comments to help me decide on the right amp. thanks for all your help in advance.

I finally found it.. I just got a mint Sony Mobile ES Amp. I forgot how nice they were. will do my front stage justice def not xplode crap. 50x4. 1 ohm stable stereo. xm-5046. I'm pretty happy..

Hey guys, I have a good friend who is putting a tablet in place of his head unit. That will leave me with an opening of about 12"x12"x4" to place an amp for him. Does anyone know of or can recommind a 50x4 class ab amp that will fit in those dimensions without getting overly hot? I dont even know what to look for as most amps are bigger than that.... I have heard of mini amps but not sure of sound quality? His budget is less than 150 bucks so PLEASE help lol Thanks in advance!

I am getting a lot of different noises coming out of my speakers. I have had this problem for a while. I thought it was my pioneer head unit but I guess that proved to be false. I have installed all new grounds and everything is wired correctly. I am getting not only alternator whine but ... noise from when I turn my fans on (ac/heat etc) and the noise increases as I increase the fan speed noise when I turn my signal light on or yield lights on - they noise pulses to the clicks of the signal lights noise when I turn my interior lights on and as the lights dim the noise dissipates. The wierd part is, if I turn my car onto accessory the noises are no longer there. These no…

So i just put a new battery on my wifes yukon like 6 months ago...and i turn it on now and the voltage drops very rapidly..i turn on just the switch with the truck off and the voltage goes from 12.3 down to 10.6v is it the battery or is my alternator not charging it right? Its the stock 160a alt...

http://www.bestbuy.com/site/olspage.jsp?sk...d=1198888991131 Does anyone know something about this amp ?

When i try to turn on my truck it crancks but then it doesnt go on.. I try again and it clicks...if i get a jump it starts and it shows normal voltage...i unplugged my system but it still keeps on doing it...plus i have the big 3 and the fuse from alt to batt melted...not blown just melted the casing...

Ok this is the 2nd time in about 6 months this has happens. First time I just wrote it off and replaced what was needed.. Now I'm wondering why.. I noticed my voltage acting funny as if my alt wasn't charging. Pop the hood and I've melted the wire that I have put between alt and battery. Like I said...2nd time same spot. I have a pos db alternator 220a ho alt. I used knu cca 1/0 for a pretty short run between alt and bat positive. Fused with a 250a fuse. Battery is a kinetik hc2000. 1st time 2nd time Both times the fuse did not blow. The fuse holder isn't next to anything hot enough to do that kind of damage. Now I only drive this vehicle maybe three times a month so …

So today i turned on my car while leaving class and decided to bump on the way home. Well i couldn't because my sub wasn't working. It was working before class. I got home and hooked up my other working sub which i decided to upgrade from (VIBE slick) and that did not work either. I know for a fact that the vibe isn't blown and my amp tells me when a sub is blown, wired wrong etc. The amp said everything was fine. So i hooked up my old amp (a kenwood) and that amp didn't work either with both subs. I can't stress enough that the VIBE is a good working subwoofer. I checked all of my fuses under the hood and none of them are blown. Neither are the fuses on both of the amps.…

I have a problem starting my car (Toyota Celica, 1.8l engine) at -20C / -4F using a HC800 as a starting battery, and I'm trying to find out if the battery is dying or if the efficiency of a HC800 at this temperature is so low that it actually has problems starting a 1.8l engine without being busted. My car don't have any stereo at the moment, the only thing unoriginal is the cd player and the battery under the hood. So what do you all believe, is the battery busted or is it alright? edit: I'm using the car for longer trips, minimum 30 min trips, so the alternator should charge it sufficiently.

I have an eclipse 3640 4 channel high amp. I was wondering if anyone knew of a link to a full spec sheet. I got a new high amp, and was hoping to have a full spec sheet for potenial buyers.

Ok so I understand that if you dont want to deal with upgrading your alternator, you put more reserve of power (aka batteries). However, I understand that if your voltmeter tells you that voltage is below ~12v, then you are running into problems. I have a question regarding this. Let say I play my music and I see voltmeter says 11.9v but I already have my main battery upgraded, and an extra battery. At that point of having 2 batteries, will my problem be easily fixed with ANOTHER (a third) battery or would I have to get an H/O alternator? Reason Im asking is because a group 31 is ~$300, and an alternator for most cars is also around that price. However, I have a BMW and g…

Hey guys quick question. I got a dodge challenger and I upgraded my starter battery to a kinetik hc2400 and then I recently added a hc1800 as a secondary battery. I recently brought a dmm to mess with and check the Ohms of some subs I had lying around. Then decided to check my voltage . So both says it rests at 12.8 then I started my car and the main battery read 13.78 or so and I checked my secondary battery and it read 12.8 like nothing happened. This is the first time I've ever checked my secondary battery, I've had a dual battery set up in my altima. And I had the LCD volt reader and my secondary battery was in my spare tire area under my sub so I never really bothe…

I have a 2.2L 2002 Oldsmobile Alero and am having a tough time finding a high output alternator bigger than 150amps. I'm just wondering if somebody has this car and purchased one, I called a place and they said an alternator made for a 1999-2002 Chevy cavalier MIGHT FIT, so that's a take a chance and hope you're right. I am running 2000 watts right now, my alternator fried today and have been searching for hours trying to find one but nothing comes up. I figure I might as well get one now instead of wasting $100 to get a new 105amp one. Otherwise would a second battery work after the big 3 upgrade? I have 2 1000 watt alpines and 2 pioneer premiers ts-w3004spl but will be …

Now that iv figured out an AudioQue 2200D would be a great choice for my Fi BTL N2, along with my Phoenix Gold 500.4 for my component speakers, i was just wondering what kind of electrical upgrades i would need to support this. (~2700watts). Iv read up on what is needed and im seeing a few mixed results. This is what im thinking: Big 3 240 Amp Alternator Kinetik 2400 Now the kinetik would be replacing my stock battery instead of running my stock and the kinetik. If anyone thinks thats not enough, or i should keep my stock battery or any other ideas it would be a great help.

Hi there I just bought a 15 inch nightshade and need to pick an amp to run it. I want to get an amp that can run it at 2 ohms. Money is a lil tight,.. I was thinking about a hifonics brutus that does 1700 at ohms or a Power acoustics that does 2600 at 2 ohms, these are affordable amps but i dont know how good they are or if they over heat i would love some suggestions or links to amps that can run a 15 inch nightshade and get it LOUD without over heating or messing up the battery or alternator and is efficient and all that.. if someone is selling an amp that can push this sub please let me know. thanks!!

What do you guys prefer... Rockford or sundown

I just switched out my old Kenwood subs and 500 watt amp for 2 12 in icons and a bc2k and there is almost no output from the subs. I didn't change any settings on the head unit and I double checked the wiring they are wired to 4 ohm so I should see 700 watts. The amp is on and not in protect. The bass is so quiet that the factory speakers are louder. Anybody have any ideas on what could be wrong?

Hi, I was buying a pair of KnuKonceptz Krystals, but a few days ago I heard something bad about them. someone told that Knus were made by the same manufacturer of Stingers, but was a kind of second line. Is that true? Are they any good? What would you recommend to me instead of them? Ps.:My last ones were Monster XLN301. Thanks!

ok im in for 2 sundown sa-8v2 i have a few ideas of the amp i want to run but i want to know some of your opions on which amp i should run?

Here is my progress of the Big 3 on my Sentra. http://i35.tinypic.com/5flyyu.jpg Now here is the stock grounding point for the battery/engine chassis. (That little screw back there) Since it is in the most extremely awkward position, can I instead ground to here with the new cable?
