need to replace 2 ohm sub in suburban

I have a 2002 Chevy Suburban without the Bose system. It has an 8" sub which now rattles easily. Any deep bass  just sounds horrible at any volume. I know it's a crap sub to begin with, but it has become much worse.

Anyway, it's a 2 ohm sub, 8". These pretty much don't exist as far as I can find. So the question is...will a DVC 4ohm sub wired to 2 ohm load provide the same sound levels as the SVC 2 ohm? I have already tested a 4ohm SVC just for fun and obviously it was barely audible.

Again, will the DVC 4 ohm sub sound the same wired to 2 ohm as the 2 ohm SVC it wold replace, ignoring efficiency differences between speakers?

Thanks...I hadn't seen this question asked...and, as this is a company vehicle, I can't replace the amp...but they will never notice the sub.

i have done  a couple of tahoes/suburbans/navigator/expiditions with that problem. What i tell them is they can do 1 of three things. 1 leave it and deal with it. 2 go to the dealership and get it replaces and be overcharged. or three we could custom build an enclosure back where the stock sub is and put a 10in with an amp running off a hi-lo and it sound worlds better then the stock ever did. we for the most part have done 10w3s in the stock position running off a MRPM450 and it work fine and sounded great. Something to think about.

jvillefinest - The last option I have thought about, except moving the sub up to under the console instead of the rear.

However, I am still interested in the original scenrio's workings. Will a DVC 4 ohm sub, wired in parrallel for a 2 ohm load have the same loudness as a SVC 2 ohm sub, given the same output from the amp, designed for a 2 ohm SVC. I know why the 4 ohm SVC sounds quiet in this scenario, but I don't know if the fact that a DVC speaker is actually two motors will do much the same in halving the sound (or therabouts).

Thanks

Asked and answered, again the answer acoustically is no. The driver can indeed be a dual 4 ohm driver and wired in parallel to a 2 ohm load BUT the other mechanical parameters of the sub would need to be identical to the one that came out for it to be the same as before. It is a crapshoot here, it is either going to be louder or quieter, sound better or sound worse and you may need to try different subs until you get the one that works best.

Every speaker sounds different as all of their parameters are different.

forbidden - mabe I'm not asking right... What I mean is....

I know every speaker sounds different and has it's own design induced sound characteristics. My question is across the board of all SVC vs DVC subs. I know if I take a 4 ohm SVC sub and put it where a 2 ohm SVC sub was, it will sound much quieter, at the same volume level at the HU. And a 1 ohm SVC sub would be much louder. The brand or design would change the quality of the sound, but the loudness of these setups should change dramatically. ( I would assume an aftermarket 2 ohm SVC would sound better and a little louder just from quality)

My factory system is setup with a preset amplification to the sub, bass settings on the HU aside. So I need for the replacement to be fairly similar to the original or I will have to crank the bass way up or down on the HU to make it bearable, but then would throw the other speakers off in the rest of the car.

So, in the end, my question is, would a 4 ohm DVC wired parallel to 2 ohm be more similar to the 2 ohm SVC it is replacing, or would it be much louder or much quieter like in the example above, minor differences from different brands or models aside?...is it in the same ballpark?

Thanks again for the answers...not trying to be a pest or a p***k.

OK...that's what I want to hear.

And actually, on another related note, does anyone know if the signal from the HU to the powered amp is high or low level audio?

Thanks
