Hello everyone fairly new to the forum. Currently have the stock subwoofer in the back because i haven't had time yet to replace it. trucks only 4 months old. I sell JL Audio equipment and know how well they're product is and am still interested in other subwoofers that run well with certain systems. I want to put (2) 12s under the rear seat. I'll figure out a place to mount the amp thats not a problem but i love having some boom in the truck, especially when i start competing in the auto shows. Any ideas for boxes and or box/ sub combo? just looking for ideas and maybe a direction to look to. I currently have a friend of mine at a audio shop price me out at 1900 for full custom fiberglass box, two 12s, and amp/ wiring etc installed so idk if i can find something cheaper, like significantly cheaper, that i can do on my own, or should i just pull the trigger and get it done through a friend. thanks.
