I got a '64 Chevy Impala SS; near excellent condition.  Nothing was cut in regards to the car.  I do however, have a question.  I came up on several 15s; and have a 4,000 watt amp for my subs and a 2,800 watt amp for my speakers.  

My question is; does anyone know of any company that would sell custom fabricated trunk inserts or would I need to go to the local hardware store and make this myself?  

Thanks
