well the apxx its a heavy duty sub... it will have pretty even spl with the btl at that volume strap 2 kx2500.1 and ull see how it performs ... the apxx its a 10,00 rms sub the btl its a 2000rms stock witout any mods... but for that power the btl its fine if u plan to go higher power or strap two amps later the apxx will be fine
IMO the BTL would have more SQ, most people like that for daily.
The APXX is a beast of a sub, if you plan on doing any competing/upgrading, I would go APXX."
x2, but the fully loaded BTL will still do fine as well daily with double or triple its RMS. the atomic will arguably be better in the end if you were competing and giving them the watts they want. i would still go with the fully loaded BTL, though, personal preference...
