Engine Noise through Speakers

90 ST

it's really sounding like it's the deck, you can double...wait quadrupal check at this point, but hook up an ipod direct to the amp and see if the noise is there...if it isn't you will have to swap the deck. I personally haven't had problems with an Pioneer deck i've used in 16 years, but have had a ton of problems with Alpine in the past. For the record i run Pioneer in 2 of my 3 cars, the other is an Alpine, which hasn't had any problems yet, but it's only a year old, both pioneers are about 6 years old. The Alpines i did have problem,s with were years ago, cheap to high end and with in a few months.
