Factory sub enclosure costs - Major pricing discrepencies

[goochsmooch]

I just got a quote for the plastic panel that houses the subwoofer in the Monsoon systems: Toyota - $400, GM - $110 AND it includes the Monsoon subwoofer, while Toyota's price does not include their JBL subwoofer. Strange!?It seems Toyota replacement parts aren't always cheaper than the GM parts. Probably always best to check with both dealerships before parting with any cash.
