Hey guys and gals!

I'm planning to run my amp in my newly-purchased R33, without a sub. (there is far less room in the boot than my previous car)

I want to run two pairs of RCA cables from the headunit, into the boot, and into the amp, then run the speakers off the amp.

My question is: Will a headunit be able to fade front/rear when running like this? I'm under the impression that RCA line outs from a headunit are a "stable line", with no modification to the signal via the headunit (bass/treble). I do know that the RCA output volume was fixed with the speaker output volume when I was running a sub in my last car. (EDIT: they both changed volume together.)

Do headunits with dual RCA outputs allow you to fade front/rear via RCA?

Thanks!

Hi Randy

Yes you can control fade and balance from your head unit. If you have front & rear RCA outputs from your head unit, and the amp is four channel. My Alpine 9815 headunit also has RCA 5volt preouts for subwoofers, so the level of my subs can be controlled from the head unit. Hope that helps

cheers

Damo and Evil, thanks very much for the quick reply! I'm looking at a Clarion HU with the two pair of RCA outs, and I have a BOSS amp which has two pairs of RCA inputs. EDIT: That answers my question perfectly, thanks!

Cheers guys!

Thanks again, guys! I spoke to a guy at Strathfield car radio before posting this up, and he also said that there are "bass tubes" that I can buy and fit in there.

I kinda reserved that space for an amp though... i'll keep you posted!

Jah... since 2 years and 2 months ago when I posted this, i'm running a Kenwood mp3 headunit, with one set of RCA's under the carpet by the drivers side into a 130wrms Jaycar amp (bridged) into my old Sony sub. There was no way I could get sufficient low-end frequencies out of 6.5"s in the parcel shelf.

From the headunit, you can go round the passenger footwell, under the ECU in the kickpanel... from there, you can unclip the door-sill (plastic steppy thing that I never step on) and then unclip the carpet. Run them over the raised part that the seat rails bolt to, and then go to the back. Undo the two bolts holding the front seatbelt to the floor, and continue running it towards the rear seat. Remove rear seats (see tutorials on this, but it's easy).. from there, they can run under the seat and through an access hole that comes out on the left of your battery in the boot.

I bought my amp because it would fit nicely behind the false wall and sit next to the battery... my RCA's end there. ;o)

    • Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?  
    • roof rail delete used to be a thing, they were made locally for a while too
    • I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps  
    • According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car. 
    • It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
