Hey,

I recently bought a decent head unit, amp, and 4 speakers for my car. Just wanted something better than the stock setup to listen to some nice music while driving.

A friend of mine offered to install it all for me and I took him up on the offer.

Problem is there are some things are stuffed and i don't know what I should do.

I'm not going to persue it with him, so what would you do?

Problems are...

- Clips that hold door trim on are broken so it just flaps when the door is open.

- Clip to hold heater controlls broken so it just flaps around.

- Clip to hold tailgate together (it's a wagon) broken so it flaps around.

- Rear left speaker makes quite a loud hissing sound when the car stereo is on but the car is not running. This turns into a buzzing noise when the engine is running. Any idea what this could be?

- Speakers in the rear seem to be vibrating a lot. So sounds is crap, that could be to do with the panels not clipped together.

I figure i should take it to a proper car audio place to get it all done right, but then what about the broken clips i need? They will charge a fortune to get them and install them all.

Or should i take it to the dealership and get them to try and fix it?

Otherwise is there anyone in adelaide who is reputable that would be willing to assist me (of course you will be paid)

Let me know guys, as i hate driving around in a car that has stuffed up bits.

New clips from dealer or wrecker, but you will find yours are probably just bent, and/or mis-aligned and not locked in.

Get the stereo system re-installed by someone you TRUST or a decent installer, as you cant rely on wiring and other stuff being right (especially with noises from the speakers).

Try not to rely on mates to do installations unless they have background experience and people to speak to about their work (not wortk risking a friendship over dodgey work).

Hissing while car is on, is the alternator noise.. Get a noise filter installed.. Can get one from Jaycar.

Secondly, rear speakers bouncing ? Make sure all the screws are tight and securing the speakers to the base / panel that its on.

Make sure the panel itself isnt dodgy and running around.

You didnt mention anything about the amp, how is the amp mounted ?

The clips would be around at a wrecker or dealer, try ripping the trim open first, i found most my clips just fell inside lols.

Take your time, tune your headunit aswell.

Would help if you stated what gear you have man.

Let us know.

For some more advice or stuff that we cant answer, ask Chris Rogers.. audio guru. :P

kk it's a 1997 TF magna wagon (i used to have a r34 but gave it up to get another motorcycle)

Parts are as followed

Sony amp XM-ZR604 600 watt jobby to power the four speakers

Sony head unit CDX-GT572

Sony 6 x9 3-way speakers rear

Sony 16cm 2-way speakers front

After work tonight i disconnected the rear left speaker cable at the amp. This made buzzing noise go away completely. No there is no feedback through any of the speakers.

Listening to the car now you can hear the speakers vibrate in the door trims and still in the tailgate. I'd put that down to shitty installment.

Mighty pissed off i am.

ok

amp under passenger seat ( it fits nicely.) ground it on the foward seat mounts - there is a screw/10mm bolt hole there- grind the paint back and earth to that point. RCA leads run toward the radio panel and centre console. speaker wiring can follow. thats not a really big unit so the stock wirng is fine.

power can run through the grommet in the passenger kick area and back into the engine bay.

speakers- I'd be surprised if they were sealed at all. mitsi used a 6.75" speaker in the front doors and the sony ones are 6" with 6.5" mounts on them. if you have the originals make a plate up for them and drop the sony speakers into that.

rears - one of them is touching ground for a start. I'm surprised that amp didn't die.

they rely on a seal from the grills to work properly. no seal = crap sound.

as for clips - mitsi - they are all of 50c each. get all the ones that are broke. forget the wrecking yards. most of those are stuffed anyway.

how was the radio mounted?

if its cradled where was it earthed? hopefully to the dash frame and not via the radio antenna.

also the heater controls are one piece held in with two semi hidden screws in the top of the ac panel. they DO NOT have to be pulled to bits to get the radio out..

do you have dash lights?

spot on there chris!, MR XTC suggested using a noise filter to get rid of the alternator whine. dont use one,they are a bandaid fix to a problem that should never of been there in the first place.re grounding your amp and making sure the RCA leads are run properly will fix this problem. how ever if it was a dodgy earth on the head units end that can cause the kind of noise your talking about too.

the TF magna isnt the most easy car to pull apart for begginers.....atleaset thats what iv found when they have been brought to me from people that have attempted them.they just seem to break everything, especially around the headunit area.

To ad to those comments, make sure the power wires from the amp are not run with the rca or speaker wires, that would cause the buzzing.

kk well i bought a filter that completely eliminated the buzzing noise. Now as someone said that was a band aid fix so i'm getting the clips this weekend and will check all the ground wires.

He also had the amp setup in correctly, so i changed the switches on it, and now it sounds a million times better. he had also screwed with the gains on the head unit so putting those back fixed it up as well.

So really once I get all the clips done and fix up these earthing problems i should be hunky dorey.

Thanks for all your help I really appreciate it!!

    • 2 spots that my exhaust guy joined the 2 pipes together  Made a big difference. I'm now able to live with it. I can make it louder if I want by removing the HKS caps.
    • Hi all, considering clutch upgrade to support 1130 engine hp from 1650cc injectors on e50 at 85% duty cycle (1650 x (11.85/14.7) x 85%). Narrows down to these three as they can be converted to use gm 26 spline input shaft if I ever want to use transmission with that input shaft (orc1000f and r3c easy/cheap just change center hub; tr2cd pricier must change clutch discs). Pricing orc1000f similar to tr2cd, r3c about usd 200 pricier. Orc1000f triple plate 200mm. Tr2cd twin plate 215mm. R3c triple plate 215mm. Claimed max torque : orc 1000f 723 lbs ft; tr2cd 800 lbs ft; r3c 1100 lbs ft. Why orc1000f triple plate but claims lower max torque vs tr2cd twins? Is orc1000f underrated? Any info maxing out these clutches? Info on street/traffic driveability/pedal feel? Thank you for any info on them.
    • Some troubleshooting, connect up a timing light/gun with a proper ignition lead on coil 1. Hold the revs at 4~4500rpm and see if your timing is all over the shop, scattering off its tits. If so, there's a high chance your CAS is fked. But I read you have a Link ECU ready to go in, why not just skip all this and put that in - will make troubleshooting so much easier.  
    • Misfires when the car is fully warm are generally attributed to the coils (and/or the igniter, on cars with a separate igniter). They can stop working properly when they get hot for a number of reasons. Either electric/electronic, or from thermal expansion opening up gaps and allowing HV leakage. Seeing as you have replaced the coils, that could/should rule them out. But I wouldn't always assume so. Were the coils genuine? Or is there a chance you have bought some counterfeit Chinesium shit? Then we're back onto loom connections. They can fail when warm/hot for the same reasons. Inspections, cleaning of contact surfaces, ensuring that terminals are fully inserted, etc etc, are all justified. The same (heat effects) holds true for the other electrics and their connectors. AFM & CAS, primarily. If you try that Chinesium AFM, drive it around on low load until it is properly hot, but do'nt give it more load than you have to, except when you need to see if it will still miss. I'm dead serious about the untrustworthiness of the calibration of those copy AFMs. Injectors are unlikely to get hot unless the fuel is coming back around hot. You could try squirting them with compressed air or freeze spray to cool them back down to see if they are maybe the cause.
    • Alright, all the plugs looks good. Noticed that it starts to get bad when the car is up to temp, that's when things starts to misfire hard. next to do is Injector cleaning and such. Got in touch with a shop to do work on the injectors next Monday also help on diagnosis.
