Amp Wattage

[Cowboy]

I have a stupid question and I just dont know the answer or if it even matters. I'm going to upgrade my audio and like most of you there is an issue with what size box I can fit in my vehicle. Space makes bass so I'm thinkin about putting in a dual sub box made to go behind the seats (instead of downfiring like I have now) in my crew cab or I'm thinking about going from 2 subs down to 1 and getting a single sub under seat box with more power.

So now for what could be a stupid question.... Is there a difference in sound, bass, or loudness between going with say 2 150watt subs or going with 1 300watt sub?

I may be pushing 300w but not really sounding like 300w if its coming through 2subs right?

More cone area with same power = louder, unless you have a special box called a 1/4 wave. I had a single 10 in a 1/4 wave on about 600 watts and it killed my pair of 10s with 800 watts in both sound quality and loudness. The only downside to 1/4 wave boxes is the amount of room they require.

Same sub in both instances?

Yep, DC audio level 2 10.

Wheres a good place to get a 1/4 wave box DT? When you say cone size you mean going up to a 12" sub right?

1/4 wave boxes are sub specific, so it would have to be custom made to your sub of choice. I don't know if any commercial outfit builds custom 1/4 wave boxes, but I can design and build them. And when I say more cone area I mean any combination of subwoofers that is more cone area than you have now. Example: 2-10s are more than 1-12. The way to find approximate cone area is measure from the center of the surround to the center of the surround and use the formula A=(pi)r^2
