Spend the money on the yellow top! i had one in the car but took it out to put in my infinity all the interior lights will dim if the sub hits hard enough atleast it did when i had the subs and im not sure if im understanding everything here properly but u know there is a wire kit running from the deck to the trunk right just making sure u knew that that way your not spending more money. i did that and then used a distributor block to go from one amp to the other
