bought a 12" IA LI, and mb quart dsc 1500.1d. shipped the amp very quick, sub took some time due to IA hold up delays(they were very slow to respond, and gave very little notice to their certified dealers, they made worst look like an *******, very disappointed with IA, i expected great things, i got great things but that's only the product not the way they deal with sales, sales notifications and shipping details). worst was great to to business with, replys quickly on pm's. won't hesitate to do business with him again.
