info about the fuse from this kit

The 150 amp fuse is to protect the wire, not the amp. The fuse in the amp is to protect the amp. An amp will not fry your computer in your car. Don't put a fuse on the main line from the alternator it is not needed. I'd consider replacing the 150 amp fuse in the mainline with an 80 amp fuse though.

the 150 amp fuse is to protect you from a fire if there is a short betwen the battery and anywhere on that 4 guage wire

 there should be zero worrying about the cars computer!!, simply make sure that your battery connection is tight and secure!!  but that was obvious

do not fuse the main line from your battery... it is not nessesary just make sure to do a clean installation of the amp kit, don't short any wires together and everything will be fine!!

one last thing,  make sure that the ground you use for the amp is a good one, clean off any paint from the area you intend to use, because if anything really causes problems when installing an amp  its the ground. just make sure of that and it should be cool!

No No No No No No No

You want to make your ground wire as short as possible. Most manufacturers reccomend 3 ft. or shorter, and if you ask any installer they will always lean towards shorter. Using a longer ground will give you a better chance of getting some ground loop noise. Also keep your power and signal wires as seperated as possible.  And always use at least the same guage or larger wire than the power wire. If you (or your dad) are that concerned about needing to ground to the block (which is completely unneccesary as there is a ground strap running between them) you could add another ground strap or 4 ga. wire from the body to engine, but as I said - not needed.

I have owned a 87 buick park ave. and a 94 buick regal, both of which had loud systems in them at one time or another, and never had any problems with the computer. There is no reason at all that an amplifier would harm one, unless you spliced directly into it's wire harness :0  lol.   I would also like to add that, yes, computers are easy and cheap (comparitivly) to fix. Any decent salvage yard is usually littered with them, as there are a lot of early 90's lesabres out there. I'm not saying they're junk, just that there were millions of them made, and there are probably a couple of Olds and Ponitac models of computers that would work. 

Been thinking about it, and seriously - don't run the smaller guage wire back to the engine! I remember my brother wiring up a long small ground in a Monte and it melted in like, 5 min. and started the carpet on fire. He might of had something else wrong, I don't know but don't risk it. Make sure your ground is at least 4 ga. and 3 ft. or shorter. then there should be no problems....

....well, ok. Maybe one. Once you figure out how many amps your amp will draw, then you need to figure out how many amps your alt. has to spare. I'm guessing you've got a 100 or 105 amp alt. figure that the car uses about 60% of this, which leaves you about 40 amps to spare for your amp (ampitty amp amp amp). If you've got a 60 amp fuse in your amp, then that's the absolut most that it will ever draw, so you'll probably be alright if you are able to keep the amp out of clipping so make sure you set the gain properly! If this is your first install, make sure that you understand the function of the gain control before you ever put a signal to the amp.

I think I'm rambling now. Must be time for bed huh?

if you run a 10 guage wire as the ground  then that 4 guage wire is being wasted.

also... your dad has nothing to worry about with the big 4 guage wire, its only there to supply electrons, it doesn't "pull" anything more than it needs whether its a 4 guage or a thin 18guage wire, the 150 amp fuse is fine, it only ensures that if there is a short somewhere  that only the fuse blows and then no more current is being passed on from the battery....but on the same hand it is large enough to allow your amp to pull that much (which it wont) but it leave headroom for other amps or..god forbid you accidently touch your power and ground wires together... it won't blow quite as quickly as a 60 amp fuse...it will blow if there is a serious short  but not on those moments when we wern't thinking (we've all done it).

there ya go  keep the wire and ground in the back with 4 guage!! its all good   i've had gm vehicles before and actually have never heard of a problem due to the amp!!

once my car didn't start though because i had the battery terminal going on/off/on/off/on/off while trying to make it screw in...waited a few minutes and the computer reset itself... wasn't a problem!   good luck

the body of your car is grounded.. it is used as a "common ground" it makes ZERO difference to electronic equipment if you have an amp grounded to it..this is because of that whole wire size thing.  the sum of all the electronic components in the car (including your new amp) will not need more grounding to the battery than the stock GM cable provides. and the body of your car isn't he perfect carrier of electrons due to its atomical design, but thats rediculously intense theory!!

its good enough and there is nothing to worry about,

but now that you've experienced your first taste of car audio and installing, better have a good job, cuz its a nasty habit!!

Actually dude the body of the car has everything to do with a proper ground. A proper ground will have a resistance of below 1/2 ohm. If when you sand down the metal and attach your ground wire and meter it and find that you have 23 ohms of resistance, well that good old body of the car ground return is not all that great. If the ground return resistance can be made to get below 1/2 ohm then sure it is a good ground location.

The body of a car (primariliy GM's) is not a good ground return due to a combination of crappy metals, glued together unibody panels and real crappy weld seams or tack welds that hold seat belt nuts on.

A bad ground will cause all sorts of problems for an amplifier, like excessive heat, poor output, noise, protection mode and ultimitely failure of the power supply if the amp is prone to this (like a Rockford).

Thus again a proper ground will be checked and found to be below 1/2 ohm resistance, otherwise grounding to the battery may be the best bet. Most installers in the industry do not even check or have never been trained to check for this most important factor when grounding an amp. Do yourself a favour and get into the habit of always checking this reading.

oh yea

i realize that resistance will cause poor performance... i guess i wasn't thinking that there was a severe problem with this car

he should OF COURSE check the resistance, my honda shows .1 ohms from the battery to the ground i have in my hatch...and i (personally) havn't had a resistance problem with the 3 GM vehicles i've owned... but it should always be checked!!!  good call!
