probabaly, you would need to build a custom box, most likely a sealed, just make sure to check the owners manual for the sub and find the recommended box chamber space per sub woofer. Make sure you have enough room where you plan on putting them so that there is enough room for the sound to resonate inside the box.hi guys new here i have a question, i have a 2004 silverado stepside bed truck (single cab) and i was wondering if anyone knows if its possible to fit 1 or 2 Sundown E8's in the back seat or even under the seats ?
