Wire it in a series. One wire from amp positive to one positive speaker terminal. One wire from amp negative to negative speaker terminal. This should leave one positive and one negative termianl on the sub. Use one additonal wire to connect these two, this wire should not be connected to anything else other than the two remaining terminals. This will allow you to have the music up louder with higher amp settings without having to worry about blowing the speaker as easily.
well if the amp works with the car off and when you start it the fuse blows then you may have alternator issues use a volt meter to check battery voltage is not above 14.5 volts
if the fuse blows when the amp turns on then most likely you have a shorted output section in the amp.
Disconnect all speaker wires from the speaker terminals of the amp and disconnect the RCAs. Replace the 30 amp fuse with a 15 amp fuse. If you turn it on and it blows the fuse, it's likely that it has shorted output transistors. If that's the case, you need to have the amp repaired.
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).
What you need to do is first ground your amplifier securely then make sure all connections are fastened. don't remove the speaker connection and listen for sound. If there is no sound power down the unit, and send it to a repair shop because it sound like you may have damaged some components in the unit. But in order to come to this point you have to make sure you ground the unit properly and then make sure all of your connections are secure. Contact me once this is done and you are ready to do some tests.
I used to have one of those amps also (nice amp btw) Did you try another fuse of the same size?
Is it blowing fuses everytime you put one in or did it just blow that one fuse ?
Is the conection on the battery solid and clean of corrosion build up? Because that is a good amp and if wired properly shouldnt blow out or anything and so if the speaker is not blown then maybe connection is weak somewhere? I would try disconnecting the speakers from it and try a new fuse and if it does not blow the new fuse than amp is ok? and if it does blow the new fuse right away then there must be a short somewhere in the wire or the amp. then disconnect the fuse again and reconnect the speakers and if the fuse blows with the speakers connected but doesnt blow with them disconnected then you know it is a blown speaker causing the problem.
Just currious but what size fuse do you have connected at the battery?
