Would this be possibvle or even worthwhile? I think that sub would be enough (factory 10") if I got decent amp and used a line-out converter. Eventually I would put in 2 new 12's, but in the meantime, would this be possible?

 

NOT RECOMMENDED. My cousin is the National GM for Pioneer Canada Car Audio division and he says OEM components that are amplified by OEM amps are not compatible, nor warrantable with non-OEM equipment.

 

On this note...is the only thing boosting our speakers/sub an amp built right into the deck itself or is it somehow built into the sub casing? I'd be curious because 250W seems like a lot for just a deck amp considering most are 50W x 4 and the we'd still have to run the sub. I haven't been able to find any number on this anywhere either.

As for boosting the factory sub I'd be really careful with it because god only knows what's been changed. I saw the exact sub in our cars in a store the other day and I'm sure it could handle more but not sure how re-working the speaker output would go.

Permafried-

 

Go all the way (get a new system) or dont go at all, it wont be worht it and could casue more problems than you would like

 

Thanks all, I might just swap from my lancer to my SS/SC since my fiance' told me just now that her friend gave her a 12" soundstream sub.
