hello

i have recently bought a 2 channel fusion amp to power my 6.5 inch alpine slipts.

the amp and speakers are all hooked up correctly however when i turn the key to radio the headunit turns on fine and the rear speakers work fine (not amped) but the amp goes straight into protect. Then i found if i leave the power supplied to it and simply remove the power or remote wire and reconnet with the head unit still operating it works fine. One of my mates said something about when the key is turned the amp receives power from before the headunit. does anyone know if there is some sort of delay or anything to fix this problem or will i just have to put a switch in????

cheers

something is wired up wrong,that is the only thing that can cause it to go strait into protect...unless you were just unlucky and got a dud from new.

DO NOT remove the power leads to the amp while its on.never do it...ever.

try these and get back to me.

unplug all the speakers you have pluged into the amp including RCA leads (do not let the RCA leads touch anything while unpluged) but leave it hooked up to power and the remote turn on lead,now turn on your head unit and see what the amp does.it the amp powers on fine and doesnt go into protect then it is an issue with your wiring or RCA leads somewhere.

if it does power on fine turn it off again and plug the RCA leads back in and turn it on again. if it goes into protect this time then its an issue with your RCA leads so remove and fine the problem with them.

if it doesnt go into protect then its a fairly safe bet to say its a problem in your wiring to your front speakers somewhere so go over and check all of that again.

EDIT : just read your post again....for the love of god please dont take any more advice from your friend on this subject.

      A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.

      The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?

      So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...

      the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
