My yamaha pdx-30 does not support to my iphone 4 why? How can I do?

The speaker is sometimes disabled when you connect the 30 PIN sync chord. If the 30 PIN connector is damaged, it can cause the speaker to not work, or to work intermittently. Try using a thin object (like a safety pin or something similarly thin, preferably something non metallic and non conductive) and gently jiggle the 30 PIN connector on the iPhone while playing a sound, (like a music file in the music player). If the sound starts playing again you have found the cause of your problem. Unfortunately if the connector is the problem you will need to be careful in the future when you disconnect your sync chord.

This is most often caused by placing the iPhone into a sync port designed for the iPhone 3GS and earlier models. The iPhone 4 and later needs support to keep it from straining the 30 PIN connector on the iPhone 4 or iPhone 4S.

Good Luck.

it is not broken forer, relax, there must be only dissconnection of wire ,, check the flow of current through the wire catusiously, better take it to local vendor he'll fix it for cheap buks

Set the two switches filter to: off. You do no need filtering your speakers as they are full range ones.

Hi ezradf ,

i am afraid no it will not fit, the PDX-2300 mk 1 has a bigger fitting then the Mk 2.

Disconnect all speaker leads from the PDXf4 - test. If the amp turns on and says on ok - then turn off, and attach one speaker lead at a time until it turns off. When it does check that speaker and the speaker wire to see if it is blown, shorted out etc.

You are going to want to make sure all your power wires and grounds are 4 gauge as well as the wire leads to and from the capacitor-4 gauge also. make sure you have a very good ground - the power wire from the battery should hit a distribution block-from the dist. block a 4 gauge should go to the capacitor another 4 gauge to the mono amp and another to the 4 channel amp -every component should have a good solid ground even if you have to bust out a grinder and a drill and some self tapping sheet metal screws and go nuts on it- see if that helps you

system not configurate properly go to a pro and let them do for you you have good equipment just need to put together rite.for wht you have you can get better sound than that,,good luck

what is happening is the amp can draw the current. u need a capacitor

use channel 1 and 2 as normal, use the positive from channel 3 and the negative for channel 4 as mono 1ch, your bridged output on the mono chan should be around 200watts at 4ohms.
