hey all,

was hoping someone might be able to help me with an install im currently doing.

ive got a 4ch amp for front 6 inch splits and rear 6x9's and a mono amp for a 12inch sub.

ive wired it all up except for the front speakers running the rca's from head unit to amp and then speaker wire from amp to speaker and am getting some massive feedback from the rear speakers, the wire's are running the same way as the amp wires and there is no issues with that. i also pulled out the rca's so there was no chace of interfearance from the power but same issue, all feedback no music.

any help or pointers would be great

thanks all:)

Run RCA/Speaker wires on 1 side of the car, Power for the Amp on the OTHER side of the car.

Check that you have clean grounding, check that ground from the battery terminal to the Chassis/Body (R32 GTR has a shocking battery earth).

Make sure your grounding is less than 1 meter long from the amp to grounding point, the shorter the run, the less resistance on the cable.

thanks for the help guys,

sounds like the grounding is the way to go, i'll also re wire so im away from the power cable. while were on the topic can anyone suggest a good grounding point in the boot of the r32, i just took off a couple of bolts i found attached to the chasis, cleaned off the paint and replaced. also can i use the same grounding point for both amps?

cheers

+ 1 for what the others said, but also check your head unit. I had a really annoying interference problem with a similarly setup system and I tried everything from noise filters, re-earthing, new RCA leads etc. Ended up replacing the head unit and the problem disappeared!

    • Just planning to have the wiring neat and hide as much as possible.
    • The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.
    • Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?
    • You can probably scrub the rust with a toothbrush or something. After you get the rust off flush well with water to neutralize and you will probably want to also use a fuel tank sealer to keep it from rusting again.
    • The sodium citrate solution is designed to buffer the citric acid to keep it from attacking metal quite so much, the guy that came up with that recipe did a ton of testing on how much metal loss occurs over time and it's nothing crazy unless you forget about it for months:
