im currently in the middle of building an install on a Honda Civic Coupe, its a full Ground Zero install. As these amps will be running at a 1 ohm load and pull a lot of current and honda's charge system isnt very good. I dont want to put an extra battery in, has anyone any ideas on an uprated charging system? Im quite good at fabrication so i am willing to put an alternator of another car on if so what alternator of what car THANKS! P.S im from the uk so uk models only please!!!!!!!

There has been alot of discussion here lately about batteries and alternators. The veterans mostly agree to upgrade the alternators to higher amp units. Since you dont want another battery , my suggestion is to upgrade the alt. and maybe depending on your systems demands , a capacitor could be used. https://www.4alterstart.com/door/. Try looking here for an anternator. ------------- 99 F-one fitty

I thought Ground Zero wasn't around anymore. I had asked about their subs a while back. I agree with Rushman. I got my high output alternator from 4alterstart.com and it works fine. By the way, where can you buy Ground Zero stuff now?

Hi, thanks for your replies. As for what Im putting in the car here's the list:- JVC 701 Head unit 2 x GZRC 16 Comp front 120 rms / 1 x GZRC 165F Comp rear 110 rms / 1 x GZRF 52 Coax rear 60 rms / 2 x GZHW 30 Sub boot 800 w / 1 x GZRA 4200 4ch 600 max / 1 x GZHA 4150 4ch 900 max / 1 x GZHA 2350 2ch 800 rms at 1 ohm / 1 x GZCA 1000 cap 1 farad / 3 x TV screens / 1 x PS2 / 0 Gauge to 4 Gauge cable. As for where you can buy GZ! its also very rare in the uk to. I had a car audio shop for a while i got to meet the uk distributor i could get you some but i would have to look into shipping it. Or if you go to www.ground-zero-audio.com there are links to buy but there all in german . I recently built a GZ corsa similar gear to mine which reaches 156db i consider this brand to be one of the best on the market

I would simply find the largest altenator you can, within reason and use that, remember that that motor still has to be able to turn over so 300 amps may be a bit excessive :). Also when you fabricate your bracket make sure you have a fair bit of adjustment on it so you dont have a problem finding a belt. I would also recomend using a decent size cap in your situation because there are definatly going to be times when your system is going to demand a large amount of power in a short period of time.

Ok Raven , that brings up a question for me.........When you say the motor still has to turn over and 300 amps may be excessive , what does the number of amps have to do with the motor turning over? Just curiouse. Thanks.......

the cap situation. I am only putting a 1 farad in because im not really going to belt the system much. im mainly going for a tight clean sound with a sealed box and lots & lots of sound profing

It was a half serious sarcastic remark, but a larger altenator does put forth more resistance and makes it harder for the motor to turn over, at least thats what I was always told but I dont pretend to be an expert on the motor side of vehicles. If the vehicle isint in a cold enviroment I would not think it would matter much anyways

ok Thanks for your quick response. After I read your reply , I got to thinking that maybe high output alternators didnt free spin as much as a stock one and maybe it put a little strain on the engine such as when you turn on the AC on the highway and you can feel the engine work harder. I havent yet had to upgrade to a different alt. yet just for a stereo system but would definately concider it next time I upgrade my system soon. Thanks again.

I thought you couldn't have been serious about the power cap as I myself have a phobia of these things, although they do look nice! Thanks for your advice

no I was dead serious about the cap, I was just making a tounge in check joke about the motor not spinning the altenator. I think that caps have a very usefull but specific purpose. If caps are used properly I think they are a very usefull tool, but when a kid goes and buys one to make the lights in his honda civic stop blinking, then he is just either stupid or uninformed and mislead by friends/salesman

raven please inform me of jensen we have a jensen brand in the uk but its a really poor brand

jensens is crap over hear as well so avoid it. And my comment about salesman was made because I hear salesman sell kids caps all the time saying it will stop the lights from flashing and thats usually bullsh*t and while it is sometimes a bi-product it is not thier purpose

Yeah, I totally agree about caps! I heard people on the site comparing Jensen with AudioBahn and even though I dont think Audiobahn is a good brand, people were comparing it and choosing jensen!!!

I think they were kidding about choosing jensen over Audiobahn, but yes audiobahn is definatly sub par

Actually this does not surprise me at all. Both are low-end brand names and are fairly equivalent, but Jensen amps do sound nice and warm... until they stop working. ------------- Support the12volt.com

Thanks for the link for the Ground Zero stuff. I had just asked about them a few weeks ago and very few replied. I had a set of their subs a few years back.

What I don't get about your install, civicnut, is that at the beginning you said the amps are going to be running at a 1 ohm load. But later said that what you want is a nice, tight, clean sound. Seems to me you are going for SQ but running the amps (and so, the speakers) at a SPL level.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

the sub amp will be running at 1 ohm as i fitted one to a customers car with the same subs and it sounded nice . all the mid and highs at 4ohm sorry for the confusion.
