Amp Question - Car Subs w/ Bass Head?

    Hi I'm David and I have an interesting project that i'm trying to do. I had two really nice subs in my car, but I don't have that car anymore and I'm not planning on using them in my new car. So the question is--Can I hookup two subs that were meant for a car audio setup with a standard bass head?

    Also when I was looking at Bass Head's I noticed that they all say the ratings in either 8 or 4 ohms. However my two subs are wired as 2ohms, from what I was told. The subs themsleves are dual voice coil and each voice coil is 4ohms, as to how they are wired inside the box I do not know. I'm just thinking that if i could save a little money by using these and just buying a head that it would be nice since I was already looking to buy somethign anyways.

    Any feedback/guidance on this would be greatly appreciated, thanks!

    Car subs are way too inefficient. It'll sound like ass. Just don't do it.

    Hi, David!
    There have been quite a few other people that have wondered at this in the past. I recommend doing a search of the site. I am pretty sure the consensus here is that car subs are dependent upon cabin volume for their efficiency and don't work well for stage monitoring. You should have a more detailed answer at any time now. Good luck!

    If you're not going to use the subs anyway, just sell them or trade them for a used bass cab.

    If you really feel like experimenting, just wire the speakers in series for a 4 ohm load on the head.

    If you have the means to, take your subs and compare them against some bass specific cabinets.

    I would expect you to like the bass cabs better....but go with whichever sounds best to your ears.

    They'll work just fine so long as the room you're using them in is the same size as a car.

    lol :bassist:

    Thanks for the responses thus far, didn't realize that there was actually a difference, but it appears that there is from the reactions of the above posts.

    There are really 2 seperate issues here:

    1. Car audio subs are not as sensitive, as others have said.

    2. They are SUB woofers, not woofers. Their frequency response drops off badly above about 200hz and bass guitar has harmonics much higher than that.

    If you really want SUB-woofers, car audio subs can be decent but it's hard to find any more sensitive than about 94db (about like your average 10" bass guitar speaker). Most people really don't want sub-woofers.

    That's pretty much it in a nutshell, nice explanation ESP-LTD. ;)

    Just remember that bass-specific drivers are desinged with clarity in mind as one of the design specifications. car subs are designes to be boomy and to drown out anything that doesn't go doof-doof.

    i used to be into car audio, but now i believe that real men have PA's or instrument amps or home theatres.

    Can you imagine running my 1001RB-II and my 1x15 in someone's car? it'll probably blow the windows and suck the battery dry in 5 seconds :eek:

    I used to run a pair of JBL car subs crossed over at 150hz with a small Avatar 12" on top. I found that more often than not, I had to cut the lows to avoid rumbling rooms, and finally gave up the 'flat to 30hz' trick.
