I'm a fixit yourself person and I really need some help on this one. First of all the amp was giving to me alreadysemi disaasembled. All the N-Channels mossfits where missing sept for 1. I grabbed the number off of it and ordered new ones. I checked for shorts after installing them, checked out ok. Installed in my vehicle and it does work but,it is getting hot very fast and is also trying to melt the power and ground wire when on. I don't think them are the right power mossfits that belong in this amp. The only one in it where I got the number to replace it, you could tell that it got replaced before.How can I get a hold of a schematic or just the number off an original power mossfit so I can fix this amp the right way....

yes you have a internal fault of the amp. the circuit that puts it into
safe mode is bad and that is a very small chip on the board know as a
op amp. needs to be repaired.
Try switching around one of the pos/neg speaker wires (you may have one crossed and they are firing out of phase, meaning when one pushes out the other pushes in and vise versa causing the base signals to cancel each other out) while the system is playing, only switch one speaker,not both. You can normally look at the subs and tell if they are moving very good and not much bass is there, you could also have the wrong box for them, this will also give a similar result
I used to have a similar model, vs1405, and it was advertised to have 600w max. Its rms ratings were 260w bridged @ 4ohm. and 80x2 @ 4 ohm.
So I really wouldnt expect much.
I would personally suggest the HiFonics Brutus. Very nice amps for the price, and have TONS of power.
After Kratos ascends to the top of Atlas the Titan and unchains him, Atlas then gives him the power Atlas Quake. With it, Kratos can
summon damaging earthquakes. The power can then be leveled up to
increase its damage and receive new abilities.
wire the subs at 2 ohm each. red to red and black to black and then to the amp. if thay are a dual 4 ohm sub. dual 2 ohms will need to be wired red to black on one coil and the other conected to the amp.
it may be a wiring problem you need to make sure all the speaker positives and negatives are correct. I sell alot of hifonics amps and have never had 1 do that. it may also be a bad rca cable. if it only does it when you use the filter i would say not to use it also make sure the gain is no more than 3/4 turned up and the bass boost no more than 1/2. if you have a dif amp try a temp setup using it and if it still does it its a wiring issue. also try 1 speaker at a time on the hifonics and keep adding 1 till it comes back it may be a bad voice coil on 1 sub .
