Is normally installed directly on the battery without an additional relay. I just made a simple braid to split the original connection in two for the second bass horn I ordered. Much louder than the anemic horn on my 2010 4runner (single disc horn) though. This doesn't say much as the original horn was primarily for Vespas but they have a very noticeable improvement in volume and tone. I don't know what a "freeway blaster" is, but at least people on their phones can hear me honk at traffic lights. I accidentally honked the horn while getting out of my car with the door open the other day and was surprised at how loud the horn was. Would buy again and I see no need to do a relay mod unless you really want to get every decibel possible. Nice result with a simple installation that anyone can do.
