Hi,

Just wondering if anyone has done a DIY sub amp installation for the Sportivo 03 and where abouts did they run there power lead through the firewall??

And is it possible to piggyback of the rear speakers to run a sub?

in my first corolla i took a lead off the front speakers, in my sportivo the headunit has amp outs, i ran the power through the firwall on the passengers side through the same hole that the ECU loom runs through.

So in a stock Sportivo 2003 6Disc model there is preamp output (RCA's) on the rear of the Head Unit?

no there are no rca outputs

on the last stivo i installed on I ran the cable through a gromet on the passenger side ...

its about the size of a 5 cent coin .. nothing running though it at the moment . .just sealed with that rubber gromet ...

pull the gromet out and feed the cable in ...

from the inside... take out the glove box .. coz it will make it heaps easier ..

Mario - If you read this maybe you can post a pic of where your power cable runs through the firewall

Where abouts is this grommet? So you piggy backed of the rear speakers and ran it into the HIlevel input on the Amp?

ummm its pretty hard to explain where it was ..

imagine you are sitting in the passenger seat ...

its inline with the right side of your glove box ...

just look under the bonnet for the 5 cent size rubber gromet .. its pretty clear ..

and re your rear speakers .. its up to you if you want to run it off the amp or off the HU .. depends in your gear ??????

what are you planning to run

it's a bad idea to run the power cable through with the ECU loom.

You can run the power cable out the loom hole at the front passenger side of the engine bay, the through the cable hooks up inside the guard, and through the large grommet that goes to the passenger kick panel.

It's more work, but a far neater and safer install.

Just an average powerful amp ~200Watts RMS and prob a 10 or 12 inch sub just to extend the bass response of the system abit more into the lower region :)

I did this on the weekend with the help of Pappa Guiseppi (Azza, king of fixing the spaghetti :D ).

Power cable was run exactly where it is in that pic above. The amp is under the passenger seat so power runs down the passenger side under the scuff panel. Im running both front and rear speaker cables into the amp (as it has hi level input). At the moment its just amping the stock speakers, but in the next week or so I will be disconnecting the rear speakers to run a sub.

Stock fronts sound great amped, its just a matter of how long they will last.

So the Stock 6Disc has no Low level outputs on the back, only speaker outputs?

And if so Has any one take their rear door apart before?

The stock unit has NO RCA's. Correct.

If your going to splice into the rear wires, your best bet is under the sill scuff panel, this will allow you to run the wires straight into your amp under the passenger or drivers seat. No need to get the door card off.

Beware if you have a facelift model, as we found that although the wiring colours according to the diagram were correct, they were coming from different pins in the plug when compared to the wiring diagram on this site.

Hope this helps.

The Rear Left speaker wires should be Black (+) and Yellow (-), or Green (+) and Green /w Black Stripe (-)?

So the speaker cable runs under the door kick plastic panel ? I dont want to cut the wrong one :S

Yes, there is a loom that runs along the passenger side with the black and yellow wires in there. Be careful though and make sure you have a circuit tester to check that they are in fact the speaker wires, as there are 2 sets of black and yellows in there.

I didnt do the drivers side (pappa guiseppi did that side), but if you have the wiring diagram (do a search and you should find it on here), you should be able to locate the correct wires.

So would it be better to get a HI-Low RCA converter or just get a amp with a High level input?

You only need a RCA Convertor if either your amp only has RCA in and your head unit does NOT have RCA out, or vice-versa, your head unit has RCA out you want to utilise but your amp only has hi/lo in...

Most amps have hi/lo as well as RCA, so if you are using your stock HU, then just use the hi/lo input...

IMO - RCA convertors create unneccessary signal noise

Do i need a special connector to connect into the Hi level input in the amp?

No - you splice into your speaker outs and your amp should have aplug attachemtn for it for th hi out.

      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.
