75 - 80 percent of max volume is the most you'll ever want to turn it up. You'll clip the shiat outs your subs if you go above that. And never, ever replace a fuse with a bigger one. Very bad things will happen
There are 3 things you can do....from worst to best.
1. Turn up the volume of the radio to about 75 to 80% and adjust the gains on the amp until you hear distortion. Then back down a tad. (This is the worst way to do it, but in a pinch better then nothing.)
2. Go online and research "adjust car amplifier gain digital multimeter". You should get some links to read.
What you will do is download a test tone, and burn it to a cd. Make sure the test tone is 30 seconds or longer because you will need the time.
Put this in your stereo and play it at 75 to 80%.
In your reading you will find what your readings will be like at your amplifer on a digital multimeter.
Adjust your gains until you reach these numbers. (This is a decent way to do it...you will get more detail when you read or watch a youtube video of someone doing it)
3. The best way would be to go to an audio shop and have them put it on an Oscilliscope (spelling?) This will let them adjust your gains better then a digital multimeter, but they may charge you to do this.
Personally I use the 2nd way, and have for years.

Okay cause I've been standing by my 5A fuse while others have been insisting on going to 10 or 15, but I refused so far.. I'd just like to be able to occasionally go to 30-33 without worrying about blowing a fuse.
Apparently it's supposed to be louder also after the final touches are done, along with not worrying so much about blowing fuses, but again, no clue what that means...
Edit: I'll try that out azphat, thanks
I couldn't just rewire it to a fuse that is 15 A though to fix the blown fuse problem could I?

What they said. Thinking about it though, I don't like the fact that you blew a fuse in the car itself. Makes me think that you have a hackjob (aka cut harness) behind the radio and something is exposed or hooked up incorrectly. I can max my gains, bass boost and volume all to max(not that this should ever be done) and I may damage my equipment or pop fuses on the equipment, but I assure you all my dash lights and anything else that came stock with the car will remain functioning without issue.
Fuses protect the wire. If their is a 5A fuse in place, it is because that wire is not meant to carry more than 5A. If you increase the fuse size, the fuse may not blow, but you run the risk of the wire burning and even starting a fire. It doesn't take much to "fine tune" an amp if you know what you're doing. 2 minutes for me and that's being overly careful.

Know how to solve this? Run a dedicated power wire for your deck
Exactly.
Sounds like the stock stereo that was in there before was very low power, thus the 5A fuse. Your new deck is alot stronger and the guy who hooked it up used the stock power wire. Running a new power line straight to the battery is the only thing that will fix your problem, because whether the amp is tuned or not has nothing to do with the amount of power the deck is drawing (assuming the idiot who hooked your system up ran a seperate wire to the battery for the amp. If he was a complete F-ing retard and ran the power for the amp off that same power wire, it's going the blow that fuse very fast).
The next thing that will probably blow will be the stock speakers, assuming you didn't change those.

Not sure how he did that, I'll find out soon. He supposedly is gonna show up this weekend to finish fine tuning the amp for me.. Yes, speakers are next to go, those are stock for now
