MAXI fuse good? or BAD?

Today i went to the local audio shop and i don't know if they are just trying to get my money or what but they said that the Maxi fuse are not good. The blow easy, expensive, and hard to find. I have found them on the internet so that is not a problem. Are they really that bad or they are just trying to get my money.
Also, What amp would i use for my set up. I have sony 1000 watt that has to 30 amp fuse in it would i use a 60 amp in the distirbution block. I also have a kenwood 500 watt with 30 amp fuse in it. Would i use a 30 amp maxi fuse in the block for that?
4 guage from the batter to the block 8 gauge out to the two amps. 4 guage ground wire to a block with 8 gauge to the amp. speaker wither and Y adapter for the audio in to both amps. Thanks for the help.

Maxi fuses can sometimes be a bitch to get. Not alot things use maxi fuses besides some amps and dblocks. We use "tubestyle" fuses. If you are only going a short distance say 3.5 feet or less use a nonfused dblock. The fuse underhood protects the wire to the amp. The fuse on the amp actually protects it. but if you already have the block go AGC fuses tubestyle. About blowing easily hmm well current is as current does, 60a via maxi vs. 60a via AGC.

Nice to know but i do have a dblock and its a maxi fuse type so should i just keep it and go with Maxi fuses or buy at AGC fuse or a dblock that can hold the tybestyle ones?? What is my best bet?
Also, what do you mean 3.5 feet or less? I have a 20ft 4 gauge from the battery to the amp which is in the trunk. (20 ft is what was in the kit so i used it) And the from there the amps are really close i say less then 3 feet from the dblock to the amps. Same with the ground.

Just use your distribution block if you want to use one.

Personally, they are just for show...you'll get a better connection with a nut, a bolt, and some ring terminals. You only 'need' a single fuse or circuit breaker (what I'm running), to trip the circuit should a direct short occur from any problems with the wire coming frayed or any possible amp problems...

I don't even run any fuse protection on my amplifiers. I have jumpers across where the fuses used to be. As long as you have a durable amp and sturdy wiring you should never have any problems just running a single fuse on the power lead. I'm running 12 amps in my TA like this off of four 2000CCA batteries with no problem, and my prelude with 2 amps is wired like this as well. Never blew an amp to this day. *knock on wood*
