Going to be putting a sub in my m340. Have a quote for a custom mounted sub that would sit in the trunk floor with a custom box and metal cover. Would be 2 10in jbl and a 1000 watt amp.
He said 2400 which felt like a lot. I have an existing sub and amp which I was thinking of just bringing over to save money. Do you think best buy would be capable of connecting my existing system to the m340 without much trouble?
