Only fuse you need is the power wire leading to your aftermarket amplifier for te subwoofer. Which most likely you have too small of a gauge of wire and burned straight through it, and if you haven't, add a 40 amp fuse near the battery where your power cable is hooked up to. Also use a multimeter to test your power wire on amp, check the
on the back of the stereo you should have an rca inputs in the back, it should say either rear, subwoofer, or non-fade. all of these are acceptable, run rca's to the amp from the deck.
also on the deck in the wire harness is a blue wire with a white stripe.
hook a wire up to this and run it to the REM. terminal of your amp. this wire tells the amp to turn on when you turn on your key.
these are the only two wires you hook up the back of the stereo.
hope this helps
You need to put the capacitor after the in line fuse/ distributor block. Because you are putting it on only your subs you are running it into fail because of a negatuve ground loop which is why they play low then cut out. Also check your grounds for both amps after rewiring and make sure they are tight.
You are doing right on what you described. I really like to work with a clearly described what involved in an issue.
Now we have to use a Voltmeter to check if there is power to the amplifier. If there is power to the amplifier terminal, then the problem is at the amplifier, not the connection. Let check it out:
1- Turn on your Kenwood radio, make sure to hear sound from your regular speakers.
2- Turn remote control knob to the mid level between min and max.
3- Measure the blue wire where you spliced to ground to see if you have 12V, if it is not then the problem is right there.
4- Measure the Red wire power from the Amplifier to ground ( the bolt that you connect the negative power to see if there is 12V, if not trace back to the Fuse that you inserted between the positive terminal of the battery and the wire going through the firewall to correct it.
5- If you have 12V at step 3 and 4, then you have a defect unit, return it to the manufacturer for a replacement.
There are no subwoofer settings on the Pioneer DEH-2800MP.
You need to check the external power amplifier and the connections from the Pioneer and from the sub(s). If everything is plugged in and wired correctly, check the amp fuses, both on-board and the main power fuse (located in the amp positive lead usually near the vehicle battery).
first check that the subwoofer function on the actual head unit is turned up,second check that the gain on the amp is at bout half way then check that it is on a lp (low pass setting)
then check that the boost on the amp is turned up.
please leave feedback.
