I feel i have the amp hooked up correctly but everytime i start the vehicle the fuses on the amp blow, I have a fuse at the battery and then the battery wire is running all the way to the amp. I have the ground grounded to the frame under the truck. and the remote wire to a on and off remote wire in hte fuse box. What does this mean, am i missing something or is the amp bad? Thanks

Re: Keep Blowing Fuses
Sounds like the amp is shorting somehow. You are obviously shorting out somewhere between the battery and the amp. Are you sure you grounding location is a good one? is the fuse blowing only when you turn the stereo on? Something is not hooked up correctly.
If the fuse at the battery is blowing then it's a short.
If the fuse on the amp is blowing then its probably a bad amp.

this sound like a case of arcing power wire it happens very very easy if u use cheap wire especially from walmart. whatever u do keep using fuses and get a batt test asap. if u take out the fuses ull burn the amp like no other and plobably burn out the power rails which will be cheaper to buy a new amp after that
Are you using the correct fuse? if so,
more then likely, you don't have a good ground. Try grounding to something else that has more direct connection to your frame. If that doesnt work, try getting larger power cables.
I had the same problem with my 2500w xplodes all I had to do was get a thicker cable for the ground and battery connection. What was happening, was it was needing more power then the wire and fuse could handle, so it would blow the fuse, since the higher you have it, the more power it needs to feed the watts.
I would try grounding it directly to the frame on a good part of the frame before spending another $70 on new power cables though.
First off which fuse is it? The inline fuse from the battery or the amplifiers power supply fuse? Blowing the main fuse from the battery is caused by either the load (your amp) drawing too much current or you have a short to ground somewhere. Maybe there is a tear in the 12Vdc line and it is shorting to the chassis of your car. If the amps power supply fuse is blowing as soon as it turns on your amp has a shorted power supply. This will require internal component changes by a technician. If it is blowing after operation at high volumes I would say change the impedance that the amp is driving. If you are at 2 ohm try to rewire your speakers for four ohm. (go from parallel to series wiring then bridge mono or operate the amp in stereo mode)
the voltage regulator in the alternator or the capacitor is malfunctioning. get a multimeter on the battery when u start the car (before the capacitor) if it reads a large surge (something greater than 14 or 15 volts) then u may need a new amp, if not, then test it on the back end of capacitor to the chassie negative, see if u detect spike there.
The reason your blowing fuses is the amp needs at the least a 150 amp fuse on the wire that runs to your bat. There are fuse blocks that you can put 4 40amp fuse and theres the high dollor ones that you can put all the way to 200amp. When you trun up your amp its drawing to much current for the little 40 amp fuse that you have and will blow it everytime. I recomend Running a 4 gage wire to bat and ground with same. Get you a 150 or above amp fuse from a car audio shop somewhere. anyway sounds like from what you decribed, theres nothing wrong with your amp just the wires and fuse are not big enouf to handle the current that your amp pulls.
the wire from your battery is blowing fuses? and you are using 20-30 A fuses? mine has a 100A fuse..look into getting new wire plus my wire is 4 gauge.., 1600 watts is too powerful for a 12 g wire and a 30 A fuse
The amplifier probably has shorted output transistors.
Disconnect the speakers and RCA cables. Replace the fuses with two 10 amp fuses or a single 20 amp fuse. If the amp blows the fuse when it powers up, the outputs are almost certainly the problem. Don't try it with the two 30 amp fuses. The smaller fuses will provide more protection for the power supply. If the amp powers up with the smaller fuses and they don't blow, check the speakers and the wiring (for shorts to ground or shorts between wires).
If it keeps blowing fuses then #1 its internally damaged or "blown" .. Or #2 i would make sure you have the battery power hooked up to the + terminal and the ground wire running from the car body to the - terminal.. so if its hooked up correctly and keeps blowing fuses then it requires repair..
I wish i had better news but thats all it can be...
