I replaced the stock head unit with Pioneer FH-X700BT and Polk Dxi650 speafers in all doors. Pioneer tweeters as well. Unfortunately I am noticing a hiss with volume. I am hoping that it is because the head unit is using the harness speaker wire connections to the amp and the HU output level may be too high. I have bot a PAC Seom4 line converer and plan to hook from head unit speaker leads to the speaker leads in the wiring harness which go to the amp.
How do I adjust the gain ocne this is hooked up. I can find no information on the Vibe Monsoon system amp. Not sure if it has high input leads to begin with or not which may mean I'm barking uop the wrong tree. FIgure it's not going to hurt to try. But again, I have no idea how to adjust the gain on the converter and on the amp as well if it is necessary (if the amp even has adjustments).
Thanks,
