Will this be noticably louder

I currently have two 15in. CVRs sealed and a BX1000d and want to know if i were to "upgrade" to 2 12in. L7s sealed with a BX1500D, will I be able to hear or feel the difference?

i dont like 12 inch solo barics very much in sealed. theyre not very snappy

scratch the L7s, would i hear any difference in the bass (SPL wise) if i were to get 2 15in. Type Rs sealed compared to my 2 15in. CVRs?

no, a general rule of thumb to achieve a 3db gain (which is noticable by ear) is to double your cone area and double your wattage.

Ports help too //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

so if i were to upgrade to a 1500w amp, i would be wasting my time and money?

the bass might sound a little better, cleaner, snappier, but i dont think you will hear a huge difference is loudness. you might want to keep the amp you have and look into optimizing your install. maybe look into a ported enclosure.

go with a ported box, it may give you the bass you desire

ported sounds like the way to go.

would 1 15in. 1000wrms sub ported to whatever be louder than my 2 CVRs, or will the CVRs be louder because of the cone area?

Depends on the install and the vehicle. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Oh, so I guess that two 15" RE XXX's wouldn't be any louder than two 15" CVR's since they have approximately the same cone area??

and double your wattage.

But what about the efficiency differences between two different subs?

Before you start buying new subs and amps, I would definately try building a vented enclosure. Spending $40 on materials to find out you can be happy > spending hundreds on new equipment.

Port them, you will see a huge gain in output.

i have the CVRs in a Sentra so theres no way in hell they can be ported, but if i were to get 2 12in. subs and port them will I hear any difference in loudness?
