If the fuse keeps blowing then there is a problem inside. 1 x 1500W it either cost you more than 2k or its 1 x 1500w @ 1 or 2 ohms at 14.4v. How have you wired it and what speaker is it connected to? I'm expecting the amp to be MASSIVE and I'm hoping the speaker attached to it is a 15/18" mother of a sub rated at 750w RMS otherwise the problem could be that you are forcing the amp to overdrive with unexpected load impedance

Just looked it up. Cheap tat. That said, it should still work so I need to see your sitting diagram and what is attached to it. Have you tried turning the gain control down? Is it phono lead connected or high level input?

Its connected to a big mofo sub, the phonoleads are connected ok I have got one wire of the sub on ch1 and one wire on ch2 , could this be an issue ? Also the air hole on the sub casing is about 5cm diameter as the guy I got it from made the box could this also do with a bigger hole, thanks mate I wired one up before worked without issues this just keeps blowing fuses when turned up so unless the fuse rating is higher than 30amp, could I take it up to 40amp I do also have a inline fuse on the power wire

Do you have a power cap fitted ??

No is that the thing that looks like a can ? All I have ever uses is the inline fuse from power cable, ground to chassis' remote wire and phonoleads , tell me more about power cap

You shouldn't need one - my guess is the gain control is set too high. There should be a knob somewhere - turn it down to about 3/4 max. 30amp is plenty for fuse.

I shal turn it to 3/4 see what it does also been on the internet and looked on images of this toxic tx-1500 amp and they all seem to be carrying single 40amp fuse, the model which is toxic tx 2000 which is a 2000w amp seems to carry fuses, I think the fuse maybe blowing because of this, also when the radio or tape is on stand by like switch in but nothing playing the box seems to give continues thumping so does anyone know what this could be , thanks in advance

Yes indeed the power cap does like like a can  Well worth fitting one too and ignore anyone that tells you differently aswell It will also help future proof your stereo setup too if fitted and want to go bit crazier Helps stop flat battery's , current drain ,headlights flickering like as tho it has an old school dynamo fitted haha May also help with cutting out if too much gain as it stores some energy and keeps it on standby for those heavy bass tracks  Well worth fitting IMHO and only cheap a 1k farad cap |

A power cap is generally not needed in most systems. The purpose of any capacitor is to smooth the flow of current. It cannot create energy ; it merely stores what is already there. A split charge system is far more effective as is having the correct wiring in the first place. In an SQ system a power cap can have a place but even they use "BatCaps" ;a combination of a battery and a capacitor . Someone did once write a great article proving why they are a waste. I've certainly never needed one and neither has a friend who has ran some silly systems back in the day ; he was running around 2kW RMS from memory. One thing I would say is that to ensure that your grounds are spot on and that the wiring is the correct size ; in most cases the latter is too small which is where many of the issues stem from. But good wiring is not cheap ; I have probably transferred my wires between 3 or 4 cars now due to me being a tight git. |

ignore anyone that tells you differently as well Hmm, a little strong perhaps chap? I personally have the opinion that unless using the car for competition (Which I have done in the past) then generally, a cap is not needed. You of course are welcome to your opinion and I won't be telling him to ignore yours but nonetheless, fitting a cap will not stop his fuses blowing. Fact. The cap just stores power for ultra bassy tracks. They have their place. We are all just trying to help. |

Hey I didn't mean that as a dig ,Apologys if you've taken it that way But just meant in terms of saving on flat battery's and all the inconvenience after listening to stereo without car running ( we've all done it Lights dimming whilst listening to your favourite trap song and heavy baseline That's why it's always worth fitting one IMHO And like I say no offence intended either |

FYI, as a rough guide, amps x volts = watts. Obviously you loose some due to inefficiencies and what not but it gives you a ballpark idea for fuses.
So 30x12 = 360watts. Don't know what the RMS power is from that amp without looking it up though, as the other numbers are probably peak.
EDIT: Had a look, found very little but some forum posts mentioning that they usually come with a 40 amp fuse and are rated at about 1x380RMS into 4 ohms.

Always followed the advice of keep it simple, or go all out. So not worth mentioning fitting caps and such like, if your not even getting basic requirements for wiring / supply right. Find manufacturers spec for fuse sizes and run that. If its some cheap tat amp offering a million watts and flashy lights, id chuck it in the bin and find something basic and half decent with a sensible rms figure and run that. Ive got a little directed audio monoblock running 2 x 12 inch subs and a jbl four channel running components front, 6x9 rear (not choice) and its loud enough to curse word off a whole campsite, no capacitors needed.
