i need to find out whether the speaker is dead/ the wiring is bust or the head unit is malfunctioning.
how do i do that?
please explain what to do with a multimeter ( i have one)sr20dem0n said:As long as you don't try it on a small midrange or tweet and you don't leave it on there for long then it won't cause any problems
sr20dem0n said:Get in the trunk, unplug the wires going to the speaker that's not working, set the multimeter to read AC voltage and put it on the wires in the plug while playing music to see if you get any voltage. While you have the speaker unplugged you can set the multimeter to read resistance and put it on the speaker's terminals to see what it reads.
Thanx sr20demonsr20dem0n said:To find the size, measure the diameter of the speaker (the total diameter). If it's around 7" then it's a 6.5" speaker, if it's around 5.5-5.75" then it's a 5.25" speaker. You aren't going to find any full range speakers worth buying for that price, if this is for the rears then the best you can do is buy a pair of raw drivers from partsexpress and screw the tweets, just watch the mounting depth so you don't run into the trunk lid's torsion bars. If it's for the front, then you should really save up more money to buy something decent.
