Venom speakers
 

I currently run a pair of Venom 75w 5 inch speakers in the front of my xj. They were installed by a previous owner and are running through a Boss BA 3000 1000w amp. They sound ok, but i hear many positive reviews on the 5 inch kevlar speakers sold at jaycar for a 100 bucks or so.

Does anyone know anything about these venom speakers? Ive had a look online but cant seem to dig up much on them. Would the jaycar kevlars be a worthwile upgrade?
