Tiny 2 ohm "sub" in center console?

[aamiggia]

I just pulled my center console apart to clean the PO's 7 years coffee and I decided to check out the "sub" in the arm rest. Well it's a lot smaller than I had imagined. I think it's a 3 1/2" speaker

I don't know too much about speakers but this one is not great, although the magnet is large for a speaker that size. The thing I noticed is that it's 2 ohms. I thought most car speakers are 4 ohm. I know that if I replace it I should use the same resistance speaker or higher. If I go higher, say 4 ohm, will the power I'm sending it be reduced? Will the volume be lower at the same power output from the deck?

Have any of you guys replaced the speaker for something bigger, better? The bass box is very small and sealed. It doesn't look like anything bigger will fit. Although I could port it.

I agree, the subwoofer sucks but large magnets are generally a good thing for woofers. Yes, amplifier output will be reduced if you use a higher resistant (4ohm) speaker but the speaker output will not necessarily be lower. They do make 2-ohm subwoofers but I don't know of any in that size.

There's some careful calculations involved when porting. So, I don't recommend unless you know what you are doing.

An easier option is to build a subwoofer enclosure in the rear passenger side panel and run an additional amplifier. I think you'll be happier if you go that route.

a friend recently installed a clarion head unit and the popular speakers mentioned in so many threads on this board(front and rear doors). this was in a '96 with 9 factory speakers. it would go into a kind of "safe mode" if cranked too high or a transiant spike occured in the signal. the solution was to clip the wires to the two dash speakers and the two small speakers in the rear head-liner. this brought the over all impedance back upto something the amp could handle. we found that the sound level was far less at any given volume but the amp could now be cranked much much louder without it shutting itself off. i thought it sounded alot cleaner as well. the problem was with the four extra speakers wired in parallel, the impedance was so low, the current output was too high. ohm's law in action.

center sub

I was thinking about fiberglassing the bottom and putting an 8 or 10" sub in there, but it's too much time and money for something that is not very useful. Don't trouble with it. Get an after market face, speakers and maybe a sub in the back.

A lower ohm rating on subs is typical. People doing comps will often be running subs and amps as low as .5-1 ohm.

If all you really want to do is replace the speaker, I am sure anything would be better than what is in there, I would put the biggest speaker that will fit, and I bet even if you can only find a 4ohm, it will still be an improvement, even if the power is halved.
