capacitors is a bit pricey for what they are worth.

currently got a 320 cca bosch in the car, and theres a few cheap capacitors of ebay. but should i just get a larger battery say 400-500 cca.

does anyone know the pro and cons?

just my sub and amp is abit much for the battery atm.

thanks

the vx range is 3 years old so they dont have it on there site anymore. i've only cranked it heaps to relise my interior lights were dimming.

think im going to return my battery that ive recent replaced and get a larger one.

currently bridged running 800watts

im not going to argue, but i suppose my input will give some idea.

i have changed my battery and gone from a 500CCA battery to a 430CCA battery and i have a 532 RMS amp on a 1000W sub.

i dont blast my system that much, maybe once a week going home in traffic. I find that it still draws quite a bit of current and i give my battery a charge and maintain it ever couple weeks, i should do it more often.

There has prolly been much discussion on issues like this, but what i will say is that there is a 3rd factor - how much can your alternator charge back to your battery per hour, along with that how long is your average drive. So minus the cars normal consumption of electricity and your consumption through the audio system together from the electricity generated through the alternator. That is my semi-educated guess.

But i think it will be fine what your doing, like in my case, just keep an eye out and look after your battery.

Good luck

A cap is never meant to act like a battery. You use a cap because it has a quicker charge and discharge rate than any battery on the market. When the sub is working hard, the amp draws alot of power, in pulses, the cap just provides a "filter" of constant power.

The CCA rating on a battery has almost no baring on it's ability to discharge current.

If you are going to get another battery, i recommend getting a quality one, something like Optima or Odessy.

Arbess' point should also be considered, as it is very valid. Depending on how big your system is, you may need a bigger alternator, but just note that bigger alternators start charging higher in the rpm range.

eg: Std alternators may start charging at 1000rpm, but an upsized alternator may need 2000rpm to start charging. Thus in extended traffic you actually get a flat battery, even with your stereo off (happened to my mate).

Just to let you know: I am not an audio installer (but did get paid a few times to do it for other people), but i am an Electronic Technician.

been reading up alot of options and yes, all have their pro and cons, butt so far a bigger or secondary batt seems to be the best optoin.

im keeping to my standard alt since i dont pump my system much.

so as far as my knowledge in electrical circuits (just failed EC203....god dam it!, 2nd elec eng unit) seems like a bigger battery is the better option for my use.

when i had my stereo in my car i had 2 exide optima blue top batteries in my car and my when my stereo was on full ball the voltage would not even move a notch

on my previous car had one odyessy battery and a cap and when stereo was on full ball with the headlights on the lights would dim at certain bass points

changed over, took the cap out put a exide optima blue top battery and on full ball the lights didnt dim

depends on system setup really and how much power you are using

sometimes its wise to change to a bigger alternater, change to a bigger grounding cable like a 4 gauge way better than standard which is like 8/6 gauge.

Caps and Batteries are two different things. A Capacitator is designed to proved the extra power when u hit a bass note. because it's got a charge stored there it's less strain on the battery. The Battery will power the amps and top up the cap when it needs to. if you want to prolong the life of the battery then a cap is the best way to go. even though better batteries like Oddsy or Optimax will provide the power, it's the spikes caused by big bass notes that will lessen the life of any battery. just have a look at some good quality installs and you will notice they all have at least 1 Fared Capacitators.

      Fark what are the changes of that snapping like that, clean. Nek minnit, custom radiator goes in, with built in oil cooler like those discontinued PWR ones from yesterdeacades ago

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.
