hey guys

well had my new car two weeks now, loving it so far.

anywho my car came with the 34 gtt wheels on it, so today i unplugged my sub to see what spare wheel i had.

check the wheel, put the subs back in the boot, wired them up and now nothing.

also, the sound system still works but just no subs.

i dunno much about the sound system but its a cadence (or somthing) amy that is powering 2 JVC subs and for some reason they decided not to work.

i manage to ellinimate the following possible causes:

1: wires touching (if they did at any point there was no power running through the sound system/car)

2: wrong wires in wrong connections (dont know much about sound systems but i remember what wire connected where, but it didnt work, tried change the wires to the terminals but still nothing, hook it back up the way i rememberd undoing them but still nothing.)

there is power to the amplifier, and when i turn the key to the first notch that powers only the clock and sound system, i get one doof from the subs but then nothing with music going.

can anyone help me?! its driving me nuts!!!!

If u get a "doof" initially when you turn it on, id definatley say theres wires touching eachother and its shorting out.

If you put the volume level down low enough, there shouldnt be enough current to short it out so try turning it on with the sound low and see if the subs work. If they work, its wires making contact where they shouldnt.

Hope this helps, good luck

hey man, gave it a go

didnt work.

i also noticed that the doof at the start looks like the subs going in and out.

like its a doof before the music starts, subs flow in and out couple of times (not a loud doof) but then no noise once music is on

Ahh tht sucks, sorry mate not much else i can think of without acctually seeing it, im not exactly a guru on the subject anyways, i just know the basics.

Ill re-post if i can think of anything else but untill then, maybe get a mate to hook their sub up to the amp and see what happens, then you know if its the subs or the amp.

Do you get a light on the amp when it's on? check to see if theres a key anywhere e.g. green for OK red for protect mode.

Since you're getting the initial "doof" when the amp turns on it's getting power, if the amp stays on it's possible the RCA leads from the head unit have been knocked out. It's also possible moving everything around you've changed the AMP from low to high crossover, check on the amp for such a switch it should be in the low position for subs.

hey guys

well today i was able to get to the back of my headunit, all connections were fine along with RCA connections.

whilist i had the headunit out, i changed my headunits (one in my old car was better)

did all the wirering and presto, the subs now work!

no idea how but, thinking RCA connections in back of headunit were dodgey??

many thanks to leon for all his advice, top bloke! :P

      RB26 boost leak? limp mode?

      By niZmO_Man · Posted

      Remember our cars are 30+ years old so expect the rubber bits to leak. I'd go around your engine bay with a can of "start ya bastard" or similar and look for leaks. FYI I got my car 10+ years ago with the standard boost restrictor in place, I removed it when I got it and the car never had any issues since (besices a leaking manifold gasket). tl;dr- Look for leaks before proceeding.

      Never ending fuel pump drama

      That SSR is actually the same (or similar) as the Jaycar 100AMP SSR (which I use). They suggest the resistor to stop the SSR turning on when the ECU turns off (I believe). I personally don't use the resistor as I use the 5V output from the ECU to supply power to the SSR. I do however run a flyback diode, the old Haltech documentation was wrong too and didn't specify the fly back, I mentioned it to a few of their staff and they eventually added it in.

      Removing sump

      By elohim_imanu · Posted

      I did manage to do this without removing the engine or front cross member, but I had the advantage that the exhaust manifold was removed. I am not setup to support the engine from the top or remove it. 1. Loosen the engine mount nuts so they only have a nut of thread. If it is a manual, I think you have to remove the gearbox to engine support brackets. 2. Jack up the engine off the bottom idler mount. Jack it up till the end of the slot and nut on the mount. You need this clearance to get the pan out at the rear of the engine. 3.Break the sealant seal to sump. I found a oil pan separator tool helpful to get it started. 4. The oil pick up can be removed with the gap available.  5. The oil pan can be removed now. 6. Before assembling, do not apply sealant to the oil pick up area as your hand will rub it all off but apply to the other three and a bit sides. 7. It is a two man job to put the oil pan back, with the sealant, as you do not want it to touch anything and rub off. 8. With one person supporting the oil pan the other can fit the oil pickup 9. Apply the remaining sealant. This would be more difficult with the manifold or turbo in place, but I think it could be done. As you can see my sealant is a bit ugly, but good enough to seal. 10. Lift the sump up to the engine and bolt it on. We found it was easier to use two long guide bolts at each end to get it nice and aligned without touching.

      Rob's S Chassis track cars. Now with more s15 and less 180sx

      I find building an exhaust a really satisfying job! Looks nice!   Did you consider using an oval pipe to get the same cross sectional area but keep it above the chassis rail?
