What do you guys suggest about DIY?

Hi, alarm pros, I have read some post right here that when people installing the alarm theirselves and come here to ask the question that help them finish the installation.  Here is my case, I have a 1999 honda civic coupe with a dealer alarm I added when I bought the car.  Unfortunately, the 400$ alarm is a piece of junk that got my car stripped for 3 times either window break in/stripped.  Now, I am looking the top of line alarm just coming out "compustar 2wss-as" to replace the junk in my automatic civic.  The question is, how difficult are they? and is it possible that I can finish install it too just like others can?  Notice, I just finish built an amp/hu/speakers in my car including all the wire changing/running and stuff.  Definitely worth learning there about 2 weeks from a completely newbie to at least know how to install some car audio.  I am a well learning guy that sure got enjoyment when installing the car audio and of course, I did lots asking and research before I make any step that I am not positive with.  I know there are pro here in this forums about alarms, so I need the suggestion/help about install the alarm myself.  Tks for your time reading and I appreciate for any advice about DIY from you!!  Inadditoin, the compustar alarm is a alarm/remote start combo, and I am wondering if I am going to take off the brain/shocksensor of the alarm I have now and just replace them on the same location?  Or there's other better location to mount the new parts?

You don't get my point there, don't ever think that I am guy advertise my stuff alot since I only have some basic for car audio, how do I advertise even without subs?  I am definitely asking about the alarm installation DIY not about anything related to my driving style while I don't usually/want go to sh*tty place.  Don't ever think about I am those little youngster kids that like to show off or somewhat.  I am 23 years old student in University of California Irvine.  Don't judge my lifestyle by looking at a Civic, that's a disrespect  for me, Installation/planning/layering sounds good and I take it.

If I were you I would be suspect of the people i hang around with.  3 times?!  Daaaaamn!  I am a freshman when it comes to alarms/auto starts/keyless entry (only done 3) so I am aware of the difficulty of these systems.  I consider them much harder then a standard component speakers/head unit/amps/subwoofer.  However, if you have the right tools and patience you can do it definitely, maybe.  Get a DMM, be patient, plan, take your time, its not a race.  You should know the risks of screwing this up though, it could be costly and if your willing to drop 400 the security system, maybe the 150 for installation is not so bad?

I am sure you will find this website helpful and the people on it willing to aid you.  Don’t take Teken's comments as a attack, its not.  He is telling you the truth; DONT ADVERTISE, PARK SMART, BE AWARE, RUN STEALTH    Quite honestly I have to wonder what you are doing, were you are doing it and who you are doing it with to get your sh*te jacked up 3 times in a relatively short period of time.  You can do anything you want, but if you engage in risky behavior nothing can help you in the long run.

compustar is not easy to install the best way for you if you see some install for one time and you can do it by your selt as you can see on compustar install guide mess go to web compustar and click on suppot and click on dear suppot and get install cm3000 that way is more easy for you to install

Things just don't get smooth sometimes, especially here in LA, where almost every city has high crime of auto theft.  My car is getting into troubles for 3 times, and yes that's true but not everytime the car was stolen, only the 2nd time I pretty much lost every gear.  1st & 3rd times are window break in, and I didn't lose as much as the 2nd times since it only cost theft like 1-2 minutes to break in.  I apologize for criticize the post from tekken, and other than that, I am looking for the diy part as my major concern since I am just about to get the alarm in next couple days. 

here the installation guide this one will be a lot better than the come with compustar alarm this installtion guide for  authorized dealer use

I'm definitely not a pro, but you don't have to be a pro to know how to use a multimeter or have technical info on your car.  Anyone can learn to use a meter, and you can get a factory service manual for your car off ebay.  Most pro installation instructions will tell you how to find the majority of the wires you'll need.  Like this one.  Other than that, just take the time to learn to read the manual, get to know your car's wiring, and get comfortable taking panels off your car.

It's not that hard to do the install yourself.  The actual logic and theory behind an alarm install is quite simple.  I've done 3 so far, in increasing complexity.  The first was a clifford arrow 5 salvaged from a wreck.  It was supposed to have been "professionally" installed, but they took the same shortcuts most newbs did: t-taps, uncovered wires, accessible brain, etc.  I had no instructions and no knowledge of electronics.  Was mine a professional install?  Definitely not.  But its fully functional and, I must say, at least as good a job as the previous car.

For a clean install, you gotta RESEARCH, RESEARCH, RESEARCH.  Make sure you disconnect the battery, especially if you have airbags.  Know where you want to mount the brain, and where you want to run your wires, before you start attaching anything.  It means probably taking off the entire dash, so you can run your wires high and mount the brain out of reach and sight.  Use tubing to cover your wires, and tape them shut.  If possible, try to open up your car's existing wire harness, run your alarm wires in with it, and reseal the harness.  Don't leave wires dangling, uncovered, or zip-tied in a big cluster.  Those are all big signs that a thief can use to find the brain.

When mounting your siren, do it in an out of the way, hard to see, hard to reach spot.  Cover and disguise your wiring, and make everything as low key as possible.  Find a good grommet to pass wires through the firewall into the passengers compartment.

Lastly, you gotta be patient.  Don't rush.  Take the time to get to those hard to reach spots to mount the brain and run your wires.  The harder a time you have, the harder a time a thief will.

Anyways, I hope some of this helps.  Take it from one DIYer to another.  It's hard, but definitely not impossible.  You will learn a lot about your car, and if you do a good job, you can be assured of the quality and security you're getting.
