fusible link

If all of the grounds and connections are correct and good then there will not be any fuse blowing problems. If you have to resort to using bigger fuses you haven't fixed the problem. Just masking it.
One of the things with fuse links is that they very rarely go bad unless something serious is wrong with the electrical system. All of the onboard fuses will usually fail first. The fuse links are all supply side so if they go the issue us usually between them and the main fuse block. Alternator or wiring or headlight system or wiring are the most common causes for them to blow.
If you over fuse them you allow more current through the wiring harness and electronic components than the system was designed for. Most of the wiring is designed for 10 or 15 amps. If you run more through they will overheat and eventually fail.
I don't know how many wiring harness jobs I've done where someone replaced the main fuse with a 8 gauge wire and fried the complete wiring system.

Save your self grief down the road, go to one of the FSM sites and download the wiring diagram for that year platform and check out the whole system. One of the most important parts is the W page, showing the Electrical Wiring Schematic. It shows how everything is interrated. Playing with one circuit can effect other circuits.

I've had cars that blew the audio fuse but there were problems in other circuits. Usually someone doing creative wiring, not wanting to pay someone to do it correctly and or not having the wiring diagrams.
