Anyone here re-use the stock Alpine sub as a 2 channel or mono(wire series/parallel) wired to aftermarket amp? Any clue how many watts the stock Alpine sub could handle?

Ok let me dive in deeper. The factory Alpine system is supposed to be 552 watts. 4 channel sub plus the 8 speakers means about 45 watts per channel if it is spit equal.(probably not, but) Now if we assume that then the sub will see about 180 watts, so what if we hit it with say 300 in a series/parallel configuration? Anyone think the factory sub(as weak as it is) could handle 3-500 watts in that layout and sound ok. I realize the SPL of that weak sauce sub is never going to hit, but would it fill in for a decent sub.

I always like overpowering because it allows you room to reduce sources of clipping/distortion which are the real killers.

With the amp I'm looking at it would only be about 75watts to each of the 4 channels. Would really like to know the specs on that factory sub. I don't think that will harm the factory sub and will just provide bass fill, not looking for tub ratling thump from it.

This is the JL one, I assume specs are similiar.

According to the email I received from Jeep the sub is rated at 200W. Amp is allegedly rated at 12 x 46WRMS and each speaker is 2Ohm. Note that the sub has 4 x 2Ohm voice coils so you'll want a replacement amp that will drive into a series/parallel load of 2Ohm.

If your amp you are looking at is 75wx4 at 4ohms it will likely be 140-150wx4 at 2ohms, assume it’s 2ohm stable. Way too high for the sub, but with the gains turned way down it would definitely sound far better than the stock 45Wx4.

No need for a 4 channel. OP could do a Monoblock at 2 or 8 ohms.
