I saw a couple of posts about sub-woofer replacements, and one post was referring to a 4ohm replacement.

So - anyone replace the stock sub with a 4ohm one and kept the stock amp? Any issues, is the stock amp ok?

Thanks!
John ('08 S5 took deliver in Nov!)

would like to know this as well, thanks!

I used a 4 ohm JL sub - JL10W0-4 and it's been working fine for me.

No problems for me since it's been installed 15 months ago. Output is significantly better SPL-wise and SQL-wise.

Ok JS I will try this on my 16 A3 since the amp should be similar...

I ordered a 8 inch kicker dvc 4 ohm sub since a 10 wont fit in the A3... btw did you ever check the temps in your amp to see if they rose since you have been using you 4 ohm sub?

The amp does get a pinch warmer, but it has seen some good demands in the last 15 months. If it was going to cook, it would have probably done so.
FWIW, JL does make a quality sub. Kicker - not so much. I wouldn't expect significant results by using a lesser grade/quality sub. I'm not sure if the lower quality would also mean a stronger likelihood of it cooking your B+O sub amp.
I'm sure there are some affordable 8" JL subs from discount places like sonic electronics and such that should work nicely for you.

BTW, I see you're still researching the subject - https://www.audiworld.com/forums/aud...nyone-2722468/

Looking at your Kicker selection, it appears we're on a very modest budget here.
That said, I believe this might suit your needs quite nicely.

Thanks JS!


Yes I am researching as much as I can...

the reason I dont got to SVC is that my OEM amp is fed by two channels 100w each... and this goes to the DVC OEM sub at 8ohms each coil... Yours I believe is SVC 8ohms.

The reason I went with kicker is that they are suitable for free air, but would gladly go to something more "higher end" if possible. Pretty much what mandates here is the sensitivity.

I am still looking for as much info as I can.

Thanks,
JC
