To all 1zzfe owners with in car sound system

I was wondering what type of upgrades (eg bigger battery, cabling etc) did you do to ur car to get rid of headlights dimming

Because atm I have a 2002 corolla hatch

my mods are:

600cca battery

600wrms amp

600wrms subs

and 4 guage for amp + n amp earthing

please help cause its quite embrassing, to drive esp at night with pulsing headlights

any help would be appreciated

I reckon a relay for the lights should sort out that little issue

How thick is the neg run off your battery to chassis. If you have 4awg left use that and make another earth from battery to chassis.

yeah...i just got the stock wiring from factory...its pretty small so...imma guessing its 8gauge at the max

though ive also seen that i i have a missing fuse that assoicate with my headlight main for 40amp?

will that have a factor...because i brought it 2nd hand

Defiantly look at getting another wire from the battery to the chassis.

If you need a battery, go optima yellow top (pricey but good) or a 1 fared Capacitor (any good brand:: Rockford, Response)

yeah i was hoping not to go for a deep cycle battery as i have a 600cca battery already, and ive heard all bad news about capacitors

i might consider upgrading the erth cables to 4 gauge for both the battery neg to chassic and to engine block

would an earth strap do much?

and what are you running in ur car that doesnt cause dimming (minus deep cylce battery and cap)

and SIR NED: wat relay are you talking about?

yeah just an update....got 4 gauge wire today and hooked it up from the battery to the chassis (strut tower)....did nothing

really need help guys

also...is the child anchor point in the boot(hatchback) a wise point for a ground

any info is appreciated

cheers guys

Sorry if this seems stupid, but did you make sure you sanded the contact point down to the bare metal past all the paint/primer etc. A good solid connection is required to make it do it's job.

As for the child restraint point, so long as that section is welded solidly to the rest of the car body it will be sufficient as a ground point.

hey man

yeah i did sanded back of of my ground points to shiny bare metal...i dont know if the child anchor restraint is a good ground or not...does anyone know how to test it with a multimeter?

note: my battery is in the engine bay

will consider changing my battery terminals and cleaning the originals first though

Hi,

firstly i am very new to this forum,

Im not sure if this is going to help however, i have a Corolla 2002 hatch zze122r 1zzfe

im currently running the

Pioneer 308D4SB 12" Sub 400rms

Pioneer Amplifier GM-6400F

I have 3 child anchors in my boot 1 for each seat, im using the far left one and it has been a great connection for me,

My positive is ran through the grommet near the firewall and directly to the battery.

Try the child anchor, also clean the terminals and make sure everything is on tight, amp connections too.

Im sorry if this post didnt help

Unfortunately a small amount of dimming is acceptable due to the nature of the electrical systems in the car I believe.

If you have some spare cable lying around (borrow of someone?), try running a

New earthing cable from alternator to chasis

New earthing cable from engine to chasis

New positive wire from alternator to battery, I think last time I checked it was a decent size (4ga?) so I didn't do that.

Also I ran a 2ga cable from the battery to a distribution block in the boot and then 4ga to the amps.

Want to avoid voltage drop across the wires by decreasing the resistance (i.e. larger cable)

What type of class is your amp? A/B? D? These will then affect your efficiency, if its not D then I recommend something larger then the current 4ga you have connected to it.

Trying look for into on http://www.mobileelectronics.com.au/, thats where I've learnt most of my car audio knowledge (also wiring up my 2003 corolla).

Try just paralleling a battery jumper lead and see what difference it makes (whilst stationary of course) If it works, replace the cable with large cable. If not, at least you have ruled that step out.

thanks guys

imma gonna try and upgrade the alt etc wire to 4gauge etc

yeah i used the far right hand child achor point

i'll try the far left hand anchor point to see...

yeah my amp is a class d mono block

also..

will a light relay work or a voltage stablizer work?

also...my lights dims when i press my power windows button lol

      1999 Camry Driver's door locking hatch issue

      It's possible that it could be something fouling or dirt build up, dry, or a broken mechanism, so have a look and give the mechanism some lubrication, most likely though, it'll be the actuator. I found one for a good price on Ebay, $25 delivered: Front Door Lock Actuator Right Side For Toyota Camry 1997-2001 | eBay

      Query about the correct rotors for 2006 ACV40 Camry.

      Hi, I'm looking at a set of front rotors for an ACV40 2006, 2.4L Camry. I got a good price on some RDA's at Sparesbox. However both RDA8112 and RDA7686 show as for my car and I'm wondering what the difference is and if there were changes to the rotors during the model production. So does anyone know which rotor is the correct one? Many thanks in advance.

      It's a simple solution though? Already laying down 60k for a RAV4, so what's another 1k on a phone to make everything work seamlessly? 👍

      Your solution is akin to suggesting that switching to a different car manufacturer would resolve the issue. However, not everyone shares the same enthusiasm for using an iPhone as you do.

      Turboed Corolla Overbuilt?

      that engine will be fine, the rods are the main thing to be concerned about. The 2860 is a decent turbo for the 1zz but in this day and age I'd go for a G25-550. The injectors might be on the small side, we run DW1000's. You need a full length injector, the shorter injectors with adaptors like ID1050x dont fit the 1zz head. You don't need an aftermarket intake manifold, if you do go down that path, avoid the CNC innovations unit, it's garbage. Do the boost control with a MAC valve and control it with the aftermarket ECU of your choice, I use Link stuff on most of my builds with the G4x Storm as the minimum. I also wire a fuel pressure sensor and oil pressure sensor to the ECU in my installs. Use a decent intercooler, the better cores (ARE, PWR, Garrett, Vibrant, Plazmaman, Hypertune) work a lot better than the chinese stuff like Aeroflow. a 450x250-300 fits fairly well with custom end tanks to route the cooler pipes through next to the radiator Don't forget about the clutch and gearbox. These days I like the Uniclutch twinplate, Above 300whp you'll want to think about upgrading the 3rd and 4th gears in the box also with the SSC (Hollinger) gear set and install an LSD of your choice. If you're going to give it a hard time, you'll also want an oil cooler. I like the HKS thermostat type sandwich plates and setrab or mocal oil coolers with -10 speedflow fittings/lines (Chinese AN fittings neck down to a lot smaller internal diameter in their bends, not great for flow) You'll also want to think about brakes, Celica or Sportivo front calipers will bolt on with sportivo discs as a starting point. To have somewhere like Tunehouse do the work you'll want to budget somewhere between 20-40K

      Camry Touring 2010 Fuel consumption 15.2L/100km. Normal?

      I did the mathematics myself regarding costs vs benefits for fuel injector cleaner. I have changed from 91ULP to 95PULP and 98PULP. Price difference can be about 13 -20 cents. Compared to 91ULP, Premium quality fuel should have a better quality additive package designed to have superior engine cleaning capabilities so the engine can perform at their best.

      "Fuel injector cleaner is a waste of money" Only if you by the cheap crap if you use LiquMolly a German Product it does work and you won't waste your Money.

      Camry Touring 2010 A/C Issues.

      Hi Guys, My Camry 2010 Touring just had a regas done on it and the next day for some reason it wasn't blowing cold air but the next day it is and now working with nice cold air BUT every now and then we can hear and feel a buzz for a few secounds and today while my sister took my car I could her like a mild knocking sound when stopped but goes away when driving off. Any idea what this could be and the A/C is always working now for now.
