hello

i am currently running a kenwood 1200w sub, pioneer 756w 2ch amp, which the sub is bridged to the amp, i am also running a bigger battery than normal but when i turn up the volume on the h/u my sub starts to cut out, any suggestions anyone, maybe a capacitor???? has anyone had the same problem???

thanks

How thick is the wire from your battery to the amp and your earth wire? If these wires are too thin it can do this.

Does it cut out with the motor running?

MOBASS, yes its doing with the engine running i am running 4 guage wiring, at least i think that is how thick it is, its not to thick and not to thin....its getting really annoying, right when a good song comes on i turn it up, and the bass keeps cutting on and off its like it is waiting to gain power before it turns back on, and also my idle seems to move everytime the bass comes on any idea's????? but only when the sub is at its potenial which is rarely cause it keeps cutting out, thanks

ok, few things i need you to answer for me first.

1.is the install fresh, or old?

2. if old, has it just started doing it, or is it an ongoing problem?

3. who did the install

it could be a few things

1. you need to upgrade your engine bay grounds. you need to remember,that the power not only needs to get to the amp, the circuit needs to be complete for it to return to the battery. the stock grounds are normally around 8ga. upgrade these to a couple of 4 guages.

2. the amp may not be wired correctly, and thus not be able to handle running the sub.

Much luck mate?

Im guessing the amp is a GM5300T and the sub is a KFCW3011? If so, im pretty sure ur amp runs 380W RMS when bridged to two channel, ur sub i THINK is a 400RMS which means they are a fairly decent matchup. If there is a fault it will be with the installation. Its obviously all hooked up to the correc places etc otherwise generally they wont work at all. I dont think ur pioneer has a safety cut-off for when it reaches high temps so it wouldnt be that (normally set at about 80 degrees anyway, which is pretty hot).

Im going to second the motion that it is the earth point. Make sure the negative (earth) lead from the amp i 4GA as well, and that it is munted to somewhere solid like a seat belt bolt, chassis point etc and not to a painted surface (which insulates it).

Should be a 5min fix if they know what theyre doing.

With that sort of setup, the earth from your engine to your battery will be more than sufficient.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
    • Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
    • What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
    • FYI: Racebox RE7R Custom Tunes Released!   https://goracebox.com/.../2017-infiniti-q50-q60-re7r-tcm...   FOR GEN 2 (21+) VEHICLES, PLEASE SEE NOTE AT BOTTOM See more   But whomever tuned your car is the tuner you should go back to, AMS, Sonictune or BT Tune....
