Thread: Gm Navigation system

Can anyone tell me some specs on my Pontiac DVD bases navigation sytem that came with my CP supercharged...... I want to install some woofers and an amp and need to know if this nav system can handle it..... any info would be great such as watts ect.

adding external amps and subs won't hurt, just get the correct interface, wattage of the stock system is not a factor there, the issue with the stock systems is the factory way overrates the system (in testing the monsoon system from the f bodies only has about 50 watts total when tested to the CEA standards)
