Upgrading my system, advice please!

[Floppiness]

My current system is 2 12 rockfosgate p3's on a prime 1200.1 amp in a custom ported box. My mids and highs are both rockfordfosgate powered by a prime 400.1. Also upgraded my battery to a diehard platinum btw...I drive a 2007 honda accord

So, I guess my question is should I upgrade to one powerful 15 inch subwoofer or 2 10 inch subwoofers. I feel like my trunk is too small to have a bigger box for 2 12s. What's the best subwoofer setup for my trunk? Also on my electrical? Second battery or high output alternator?

There's really tons of subs and amps in the market. Better question to ask yourself is . What do I want from the system ? My budget ?

I'm gearing toward spl and budget will probably be around 500-600 for subs. Depends on how much I can sell my p3's in the box. I know p3's aren't the best but I got a pretty good deal on them

500 or 600 just for subs?

Sorry, 500-600 for subs/sub and amp. I don't mind buying used either.

If your looking for 2 10in subs I have a set of American bass XFL 10s for sale on the marketplace. PM if your interested

Thanks I'll take it into consideration.

My main question is, what size of sub(s) should I get? Keep in mind it's going in a trunk of a honda accord. Would 2 10's outperform a single 15? I just think there isn't enough room for dual 12's to fit in a custom box.

So you would recommend those over a single 15 with about the same rms rating?
