how do i know what size fuse i should use

[pittross]

so by looking at that your problable useing like 1500 watts pure rms with all three of those so, but you could also look to see if they have fuses on them and if they do add them up and you got ur fuse rating but i would say from front to back you would be good with a 200 or a 250

what amp you using are there bats in back how many watts is your system

its for friend but he's using 3 lanzar's vbp 3500.2 2200.2 2200.4

thank you dint know all i had to do was add all the fuses on the amp
