is the problem my fuse?

[nismboy6986 10+ year member]

my problem is that my amp goes into protection intermittetly(sp) at just about any volume but more often when its pushed. since i haven't figured out how i want to mount the amp its been banged around a little in the trunk so i took the cover off and checked everything and it appears to be fine. since i soldered 12 gauge to the speaker terminals and the box i put some more tape around the wire in each terminal and bent the two away from each othe a little (plastic got kind of soft from the soldering) that didn't help. so i put the voltmeter at the amp and about 90% of the time when it cut off i saw the voltage drop significantly. Thing is that most of time i can just take the fuse out the main fuse holder and put it back in to get the amp to come on. the fuse holder is also from a cheap scosche kit from walmart and use what looks like a big (100amp) maxi fuse. so i think this is my problem but whats y'all opinion on this??

Check your ground.

There are many reasons for your power to be dropping. If your wire is getting hot, it will change the resistance in it and will cause less amps to go through it. You may have a loose connection around the fuse area. I would also look at the ground, ground wire size. You know the power will not go in if it does not have a place to go (ground), so like ^^^^ said re-due your ground.

Like the people before me.. check your ground. Make sure that you have it connected to bare metal (like the body of the car). Also, you deffinetly want to de-solder those connections. That's most of the problem right there. The amp was built for a bare wire connection, which keeps the OHM load steady. When you add a variable like solder into the mix, you lower the OHM load, which in turn increases the heat in the amplifier. If the amp is only rated say, to go down to 2 ohms, if you bring it down farther, to 1 ohm or less, the amp will either overheat and go into thermal, or blow the fuse if the ohm load is WAY too low.

peace,

umm, solder will have no more effect on the load than wire does.

solder will not lower the ohm load... if that where the case every time we put a resitor on a board we would have to take into account the solder resistance. however with that said if you have a messy solder job and some strand or spot is reaching over and touching the other terminal it will send it in to protect quick. check your ground and make sure no speaker wires are shorting togther

rofl...lmao...

i needed that.

solder doesn't impact impedance any more than the brand of wire you use does.

what exactly are YOU using to soder with???

only way i believe ground could be better if it was welded to the car or if i used gold/platinum wire, connector,bolt,washer and nut. i think i solved my problem. i just didn't have the fuse properly in the fuse holder. you wouldn't believe how dumb i felt when i found out this.
