How do I hook up my subwoofer and amp to my ford f150?


to hook up the amp. drill a hole in the firewall, run an 8 or greater gauge cable (greater, depending on the wattage of the subwoofer amplifier) from the battery positive lead, thru the firewall, to the amp power +, and be sure to place an in line fuse within the engine compartment, within a foot of the battery. hook the speaker up, and then run the amplifier negative lead to a bare metal part of the cars chasss, and, finally, hook the amplifier remote power lead to the acc circuit of the interior fusebox (i usually just take the acc fuse out, stick the wire in the acc fuse receptacle, then re-insert the fuse to complete the circuit).

to run the radio signal to the amp, you can use a speaker to line level converter (if stock stereo). just splice them into the stock stereo speaker leads

Check the wires at the amp. Make sure that the wires are neatly bundled and clean cut when connecting them, a stray wire may be going under one of the connections from the battery input to the ground input of the amp, there for causing a direct short and blowing the fuse. I am assuming you mean that the amp's fuse is blowing. Get yourself a test light and test the wires for power. battery power?(12V) is always on and remote power(12V) comes on only when the radio is on(it should be the blue wire in color). Then make sure you have a very good ground, I always use the seat belt bolt or car seat bolt(direct to chassis). If you checked all these steps with no luck then the culprit may be your amp.

If it is a new radio first make sure your power wire is actually hot. Use a multi meter. Also you may have a blown fuse in the fuse panel. Check that. Make sure it is grounded as well. Improper ground will make it not power on as well. For this radio Blue = Remote that you run to your amp or power antenna. Insulate it if you are not using either. Black is Ground. Red = Your accessory wire and should only get 12 volts when the key is turned on (switched 12 volt source.) Yellow is your continuous power source. Hook this to your battery or other suitable continuous 12 volt power source. It also has a 5 amp fuse inline. Make sure it did not blow. Replace it to be absolutely sure. Use another 5 amp fuse. Never go higher. The other wires are for speaker hook up. If you do all this and still no power. You may have a faulty radio. Good luck.

My eclipse 33250 premium amp keeps blowing fuses when I then it on


If you have wires connected to it may be connected improperly. Check power and ground connections if they are connected properly then disconnect all RCA cables and re turn on amp if fuses blow then an internal problem exist and you must send it in for repair.

Do you have the remote on from the head unit hooked up. If there is nothing to tell the amp to turn on it wont. You can bypass this to see if the thing works by using a jumper wire from the power wire to the remote on. I don't suggest leaving it like that though cause it will drain your battery over time. You need to hook the remote on to a power source that is only on when the radio is on. Like a power antenna wire.

Fuse keeps blowing


This will happen when there is a hot wire touching within the wiring scheme or, it could be merging circuitry within the radios main circuit board, which is mainly heat related and will happen over a long period of usage.

I recommend running a complete wire check form the radio and o the amp and all speakers. check the main radio wire harness for worn or lose connectors. make sure the ground is secure and the hot wire isn't crossing.

In most cases, this will be caused by merging circuits within the radio itself.if this is the case, you will have to replace the radio.

Please rat and have a great weekend:)

You need to connect the ACC cable from the head unit to the amp. It is normaly a blue cable, you may have to extend it depending where you have mounted the amp. The ACC cable 'tells' the amp to switch on when the head unit is powered up.

It could also be a blown fuse either on the amp itself or within the wiring for it. You should have used a power cable with a fuse block built into it, check them out.

Have a kenwood kac849 600w amp keep blowing fuse on amp as soon as power is too it power wire got wet and now this can i bypass that fuse some how


It would be very dangerous to bypass a fuse. If it keeps blowing, bypassing the fuse will only create lots of internal damage and maybe a fire as well. The fuse is blowing for a reason, the amplifier is not going to somehow start working because you bypassed the fuse. You also need to stop trying to turn it on, every time it blows the fuse, it keeps stressing the components inside. You have a shorted power supply, probably water damage as well since the power wire got wet.

I repair car amplifiers for a living, and can tell you with all honesty that bypassing the fuse would be a terrible mistake to make, the amplifier would end up being un-fixable with holes burned right into the board.

Please, just take it in for service or get a new amplifier. That is the only sensible thing to do. The amp will not start working bypassing the fuse, it will only start smoking.

Amp keeps blowing fuse


I have this same problem. You have blown the internal amp. I have had 2 of these do the same thing. There is nothing you can do but report it to infinity and try to get the unit replaced.
