[QUOTE="mastershake575, post: 8912487, member: 665251"] Agreed. This thread is a few months old but wanted to point out that I've always thought it was oxymoron that these amplifiers push the narrative of high wattage at budget prices but that's not how it works. These SPL subs are very low efficiency and requires $1000+ in electrical upgrades to really get moving. For a daily setup with no alternator upgrade you're going to want higher efficiency subs like running dual adire audio shivas 12s or Dayton Audio RS12s. They will have more thermal compression, get louder on less power, and will have better SQ. Could even do a high efficiency single 15 and try to max it out, I remember listening to a single 15 ported JBL WGTI back in the day that was breaking 140db which is plenty loud (sounded great too) Unless you're building a competition car and going all out, these really big high RMS subs aren't actually practical for most people's setups.
