Sub Cutting Out At Volume

Hey guys,

Just had a quick question - I've got a little issue with my sub in my car at the moment - when I go to turn the volume past about 15 on my HU the sub works on and off but cuts out. I've got it attached to an 800W Pioneer Monoblock Amp and the Sub is a Clarion Pro dual voice coil.

I'm not sure what I can check out on it to be honest, the power cabling for the amp is very good and I never had this problem with my old sony sub (untill I blew it up though....)

any ideas ? if I can't figure it out I may take it over to Chris at audio express to have a look for me.

Hello there,

It sounds more like ur drawing too much current out of the power side of ur amp. Is your voice coils parralelled or series, and what ohmms is it then. If it dual 2 ohmm voice coils in a parralell connection (positive to positive) (negative to negative) u will have a one ohmm load and ur amp will get hot and cut out at half volume. Most mono block amps can run 2 ohmms minimum.

Good Luck

only suggestion check all wiring is secure, maybe one of the wires inside the box is loose, or check your ground to monoblock is same size minimum as your power, not having a big enough ground will cause it to cut out, also check your rca cable, play with the ends of them and see if they cut out when you wriggle them, if its none of them may be... the devil is in your car

      R32 gtst speedo out by 10kph

      Interesting, I haven't read about the issue with oil getting into the speedo in the cluster before. I'll have to take more notice with mine. The speedo on my R32's when I've run factory diff and tyre size have never been accurate as far as I can remember. The non Type-M GTS-t did come with 15" 5 stud wheels and smaller brakes, but that's less than 5% of them.

      Good to hear the condenser you picked up off my brother worked all good. Do you think there could be an issue with your AC compressor itself or the clutch on it then? I don't know a lot about them so I can't really help but keen to hear what it ends up being. Keep the build thread going man, it's nice to look back on over time.

      This is a story of my life things, I learned eventually (thanks to someone calling me out) that my enthusiasm for discussing and sharing ideas that it came across as arrogance and I'm like... WTF?!    One thing I'm pretty sure I justifiably pride myself on is knowing that everyone will have things they can teach you, and you're always going to find out that something you think you know turns out wrong - you just don't know what it is until you get there.   Just the bursting enthusiasm that comes with ADHD when you hit something that gives you dopamine dumps can come across like you think everyone else is wrong or don't matter. But yeah, I'm a software engineer by trade and also do tuning in weekends and 100% have long had a reputation for  quickly making connections when resolving problems or forming solutions that I've sometimes had to take people form a long walk from start to end to explain how I ended up where I did when it's seemed "too simple" when I've stated my initial case, and had the "WTF" type reaction when they've realised how much was actually considered haha.   My reward is that I get all the curly problems thrown at me.

      Wives never seem to find things funny. Especially when they're trying to sleep, and you've found the new funniest thing ever. I've never seen someone be able to get try and be cranky with me, while they're holding back fits of laughter... 😛   Also, I tell mine it's payback anyway. She has BiPolar. So the household can get quite emotionally wild at times 😛

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .
