I just installed a Pioneer DEH8400MP. I have a '03 GMC Sierra and replaced the stock HU. On the stock HU I ad two inline output converters with an amp hooked up and there was no engine noise. After installing the Pioneer the engine noise is pretty loud. Any suggestions/advice on what to do/check would be greatly appreciated.
Thanks,
Eric
