  • 250 watt subs affecting harddrive/other computer components?

    Ok, i have a question that doesn't seem has been addressed yet. I am putting an Mp3 system and subs in my car. In the trunk i am planning on putting the power inverter, amp, 2 250 watt subs, and a surge protector. Is it safe to put the computer backthere with them? i would think that the subs would screw up the harddrive, but no body that i have looked at has mentioned this.

    My friend had a Stang he had some subs right next to his box, with no shielding - his subs totally screwed up his hd.

    It should be easy to sheild though, and I know his were like right on top of each other.

        I have 2 12w6's in mine and everything is fine. I have an external HD and that is in it's own case w/ fan and then the HD in the computer case itself.

        Everything is running without any problems.

          you could take away a lot of the magnetic waves.

          Suppose you have a square sub-box, there's one side where the woofer is mounted. now take the opposite site of that box and mount a big metal plate on the inside of the box.

          That should take away a lot of the magnetic waves

              You said 250 Watt subs. Are those Pyramid 350 watt subs or Audiobahn 250 watt subs....it makes a huge difference. All subs are not created equal and different manufacturers either overrate or underrate thier equipment. If they're pyramid then they have tiny magnets and would probably blow if you actually tried putting a real 250 watts to them. If They're JL or Audiobahn etc then they have huge magnets and are probably underrated.

              The point: The better the sub, the bigger the magnet, bigger magnets would be more likely to cause a problem.

              P.S. I've never had my computer next to my 2 Audiobahns so I can't personally relate as to whether it would actually cause a problem.

                As long as the hard driv isn't right on the sub magnet which it wont since it will be in an enclosure anyway. Anything more than a foot or so away shouldnt be a problem at all. That should be achivable in most car boots.

                  You can use anny ferris (I.E. Magnetic) metal to shield them.

                    Magnetism isn't your major problem, It's the pure vibration of the subs that causes failure of the drive.... I have a hard disk sitting ON a sub for a test once, and it was there for about 12months. It still works fine, but the sub was never operating. Besides the HDD has a huge aliminium chassis anyway, so it's pretty shielded. It's more the physical side that they die from..... Well that's what I've seen anyway. Just mount it in a way so the subs can't shake the crap out of the drive

                      ok thanks everyone for the input - sorry i haven't checked back here for a few days. How does this sound:

                      The two subs will go in the box in the trunk, but the computer will be in the tire well under the carpet. i will have a hose connected to the fan so that there will be ventilation, and some foam to keept it from bouncing everywhere, and it will be a good foot away from my subs so i should be ok. only problem is, ,my damn box is SO BIG, that we had to kick it in, i dunno if i will be able to get it out


                      but anyhow, if i get a flat i will just call USAA Road service

                        2 rockford 10" dvcs running at 500 watts a piece with computer sitting smack dab in front of the sealed box for 3 maybe 4 years now. Haven't had a bad sector yet.
