Hi Eric,
Yeah, it should be $300 for the 2 channel mod, plus parts. You'll probably spend $50-100 for Blackgates.
If Stan's friend still has Jensen caps, I would recommend putting those in too, they cost $50 for 2, and maybe $30 to install.
Stan is hard to get a hold of, best time is afternoon and evenings. Just keep trying, he does not answer his phone sometimes. I know you will have to wait a while. Mike is getting tired of waiting for his 1000, which Stan has had since September?. Stan is now flooded with 1000's, because of the Tweeter sale.
