You can't use two amps to power one speaker, expensive things break.
Can you be more specific in what you're trying to do? If it's get more bass out of the factory sub, adding more watts to it won't make it go boom any more then it already does.
If you want the best bass on the market in a 10" sub ( I think that's what FW used) , go with a JL 10w3 but it can't get wet.
If you don't wanna spend $300 for a non marine rated speaker and want something 99% as good? Go with the Polk MM series of subwoofers that are marine rated.
You'll also have to measure the sub enclosure to make sure it has enough volume for a real speaker, not that junk four winns installed.
No no, I'll be more clear.
Mine has a Clarion 4 channel amp from the factory, 80W X 4 RMS. It powers four Focal component speakers, plus ch 3 and 4 run mixed mode and also power a sub. The sub currently is an Alpine SWR-M100. I was looking at replacing the amp with a Kicker 700.5 to power all, but got a really good deal on a 500W (bridged to 1 ch/4 ohm) Polk marine rated amp. So I'm going to leave the Clarion power the speakers, and give the sub it's own amp. Maybe then I'll be able to hear the sub, as I currently think it's not so great. A new box is going to be built also, and the compartment it's in vented.
I just can't remember if the factory ground is run to the battery, or to a grounding block somewhere on my model.
Also, how do you hook this up with two batteries?
