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)

    • I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.
    • My Nismo 1.5 churps a bit on reverse turns when cold, but besides that feels like a stock diff.
    • Yes, but, I paid cash and I'm pretty sure the receipt was in the bin 10 minutes after I got home Note to self, keep all receipts
    • Bunnings would have just handed you your money back on that one!
    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
