Just installed my mates system for him, sub 6x9's and head unit. Didnt notice it before I put the amp and sub in but when we took it for a "fully sik test cruise" every 10 seconds or so the sound cuts out for a split second, the song keeps going but just for the split second there is nothing, no idea what could be causing it ... I would give you specs of the system but all I know is he has my old JBL GTO400 600watt amp and a 12 inch Pioneer sub. dont remember the model of the deck or anything, so anyone shed some light on this for me

cheers

Sam

12 inch pioneer amp??? lol

Whats the rating for the sub?? maybe your amp is playing up on ya... might be cutting out coz of hign voltage or bad signal...

The problem is most likely the amp im guessing. Are all the speakers cutting out or just the sub??

If it is all then the amp is your culprit. I suggest temporarily fitting another amp to test and see...

If all the speakers are hooked up to the amp try to plug some directly into the HU.

If all speakers/woofers cut out-

Check all the wires to each speaker/driver. If they short it will cut-out from the HU.

If it's just speakers connected to the amp that cut out-

Make sure your groundwire isn't jumping around and it's in securely attached. Also make sure it's the same guage as your power cable.

Make sure your 'remote" (usually blue) is connected properly and getting current. If it's falling out or jumping around your amp might be being told the HU is off.

Also - if your HU lights cut out (ie. the power to your HU cuts out as well) then you may not have enough current to your HU in which case it's the incorrect power cable you're hooked into or ground wire is lose.

Other than that if all your speakers are hooked up to the amp and you can't be bothered hooking up some speakers to the HU I would put the amp in the car where you can keep an eye on the light and see if it's cutting out.

Hope that helps. Let us know how it goes.

Well if only the sub is hooked up to the amp and yet all other speakers (I'm assuming they'd be then hooked up to the HU) are cutting out then theres no reason to think it's the sub thats busted.

If all the speakers cut out, but the sub stays on (even though the driver cuts out) AND the head unit stays on I'd find that quite strange.

I would say it's quite strange if the HU stays on but doesn't produce any output. I wonder if it's possible the current is dropping enough for the HU to be unable to produce output but not enough for it to turn off. I've never seen that happen and don't know if it's possible. When your mate gets back see if it happens above a certain volume. This might give you a clue to this fact.

Good luck - let us know how it goes slash when he gets back.

    • As I've said elsewhere, I am using the stock intercooler piping path in the engine bay, and a return flow cooler, and making ~250 rwkW (without any effort put into trying to turn it up past there just yet) and expect to be able to make some more, and frankly, I would be perfectly happy with 260-270rwKW. This is peak road Skyline usability territory. You go past there and, sure, the car will snap necks more when it's on boost, but it will also break shit all the time, cost a (even larger) fortune in tyres, etc etc. Anyway, I also do not like the over-the-fan pipe path, and you don't have to do it.
    • I see, honestly I’m not too fussed about the looks. The only reason to go plenum is to make the piping easier instead of the classic over the rad etc. 
    • Not easy to quantify wrt something like how many fractions of a second slower it would be over 0-100. But given that a 250-300rwkW car is able to do that launch sprint in 5-6 sec (and faster with appropriate tyres, and surface)..... giving up as much as a second would feel like torture. A ~450HP capable turbo is not going to make lots of boost in the 2000-3000 rpm range. So, whilst with some boost on hand it will be faster accelerating in that rev range than your engine currently is NA, it will not feel like a fast car until the boost is solidly in. You know what your car feels like right now when you open it up at 2000rpm. if you've ever been in an actual fast car, you will appreciate that the NARB25 is.... not exciting. Well, add some boost and it will be better. But shorten the intake runners and it might not be better at all. It might come out better, but it could end up feeling the same. For me, it's not the 0-X km/h sprints that matter. It is easy to fry the tyres with anything over 200 rwkW. You can't use all the power available in 1st and 2nd anyway, you have to modulate the throttle. What matters is how the car reacts when you're driving in traffic in 4th or 5th and have maybe 2000 rpm on board, and you want/need to add some speed quickly, and don't have time for the downshift. It won't make boost, it will be all NA (at the speeds we're talking about - remember how fast you're going at 2000 in 4th! and don't plan on breaking the limit by too much.) So giving away NA torque is not what I would consider practical for a street car. And retaining that NA torque builds boost faster which makes the car faster. The flashy plenum is not actually better, unless you're looking at a track car where you can keep it on the boil all the time.  
    • So how much difference does it make you think? Like 1 second in the 0-100?  I was have smaller turbo so hopefully that spools quick GTX2871.  currently it’s NA so you can imagine pretty slow, but I do want fast accusation a little as there’s not many places I’ll be driving where I go over 80 even near me. So 0-60 and 0-80 targets
