12” Subwoofer audio package Subwoofer is loud and clear for someone looking to save space. I had it in a regular cab/ single cab f150 and it was perfect. The epicenter is for someone trying to get that extra power out of it or for songs with little to no bass. The 4 ch amp is also very loud and clear. Its a dclass amplifier wich means you can use it for high output ratings. Looking for 250 obo but shoot me an offer. Everything is still under warranty. Or im also considering a trade for 2 10in subs with dual coil since i no longer have my f150 and have more space to play with in a suburban. Epicenter n Sub both come with bass remotes to adjust at your taste.
