i need help i got a 1999 gmc sierra ext cab i was wondering if you could fit 2 15 in subs in the cab  

Hi Scotty. I'm not an expert when it comes to car audio, but I've seen a lot of guys install woofers under the rear seat. Your options also depend on how far you're willing to go in terms of changing out the factory stuff. If you're willing to tear out your rear seat, you've got plenty of options, but if you want to keep them and do more of a "stealth" install, then that'll determine how far you can go. Anyone else have any sub install tips for extended-cabs?  

my friend has 2 infinity  15's in his ford ranger ext cab, he just took his back seat out,
