Hi there I've just hooked up an amp using the rear speaker inputs rather than RCA input.  There is a bit of hiss when volume is low.  Is this normal and will unning off RCA's help.

Thanks

Ben

Hiss, i hate that, especially when passengers notice it and go, 'whats that sound'

Anywhos... i had this problem and found that my wires running from the head unit to the amp were running with power cables. When running cables try to isolate them from other cables, esp. powered ones, as much as possible. this will minimise hiss.

Hopefully you can upgrade and employ some RCAs, and dont go cheap on the RCA's either. get some shielded ones.

If you were like me and still had a slight hiss when all was hooked up, try using a filter on the inputs at the amp end, or Run a wire from the grounding point of your amp back to the grounding point of your headunit. This worked for me.

Running speaker lines next to power cables will have little effect on "hiss".

Running RCA's next to power cables runs you the rish of introducing "alternator whine", which is different to "hiss".

Conclusion: Run RCA's.

      Only if you do not You will not be able to drive it with any serious load without risk of it pinging, which will either slowly or rapidly kill it, depending on how bad it is.

      Hi guys, I’m new to the GTR scene. Picked up an R33 GTR earlier this year that needs a lot of love. I’ve been going through the hot side, changing all the gaskets and while it was all off I managed to score a set of -9s. It still had the stock ceramics so I was pretty happy to get the 2860s.  I live in a small country in the pacific with 0 performance car scene. No dyno’s no performance parts, let alone stock parts for a skyline. I order everything from Australia and do it myself. This means I’ll be running the stock ECU. Maybe down the track I’ll get an aftermarket set up and do a remote tune.  Will the car run -9s on stock tune safely?  I have a very heavy foot so I really hope so 😂   thanks guys

      Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold?

      By GTSBoy · Posted

      I'm not sure if it will bolt up, but.... I'm reasonably sure that the ID of the runners is somewhat smaller on the NAs. So it probably wouldn't be a good match at the flange where the top and bottom meet. So that would be a reason to not do it. And the skinny runners would be the bit you're keeping, which would be a reason to no do it. You'd want the big runners if you were doing any work to swap stuff. Why not just use what you've got, like nearly everyone else who has +T'd an NA? You don't need or want the TCS throttle or other stuff that is specifically DET inlet/crossover.
