Blown amp, on circuit board, connecting fuse and power connect.

Most common problem is cable connection. Wiggle each lead, positive, negative in turn at amp. while playing. I assume you have checked that you haven't inadvertently muted the system.

the fuse holders are for the channels if 3/4 work an 1/2 dont an the fuse holed is disconnected , try turning on ur amp an playing a song an pull out the fuse that is connected to the bored an see if it stops playing if it does then , u would have to hook that other holed up to the bored where it was before

When I installed mine I had the same problem because my Remote Power wire didn't have a good connection to my head unit, I would just double check that along with making sure your GND wire has a solid connection to metal (make sure you remove paint if there's any on the metal). Make sure none of your fuses are blown of course and that you have a solid connection to your battery as well. I only ever installed one setup (my own) but I hope this helps some.

It's not bad, but at 400 watts, it's a bit underpowered
It'll be plenty loud, but the amp will distort before the speakers do, particularly if your subs are wired in parallel (as dual-driver boxes are typically wired)

Listen for distortion, and turn it down a bit if the sound gets fuzzy or static-y sounding

If the amp is 1200 watts at 2 ohm stable you will want to set up the speakers as parrallel and bridge the amp. That means conncect the speakers with + to + and - to -. Look at the amp connections. Usually thereare connects that look like this:
+ -
+ - + -

If yours look like this use the diagram on top. You will use the + for the left ouput on the amp to the right - on the amp. This will allow you to use all the power from the amp. Be sure to lower the gain as to not pop the speakers or amp.

What info do you need? All amps are exactly the same and the manual only differs for specific specs and db ratings!!

Serious short circuit on your output transistors, need replacing.

Because there are so many different case and motherboard combinations sometimes it can be difficult following the instructions for connecting the front panel, USB header and audio header.

Below is a few generic guide that should stop some of the confusion with the labels on the wires.

***Please note this is a generic wiring guide and we can not guarantee it will work with every motherboard. Please check your motherboard manual first. Wiring the headers wrong can cause damage to the motherboard and case, this damage is not covered by the warranty***

another handy USB wiring guide can be found here http://www.directron.com/installusb.html

this maybe easier to follow

because the power inlet to the fuse is blown ur amp will not get power, i have the same prob.
just the other way around , i blew the ground..so ugot to get tht power fix then u wil have no problem

open the amp and see if anything was blown inside, if not check replace the fuses, and re connect.
