Tell ya what. Take a look at http://www.bcae1.com and find the section explaining pre-out voltages, or amplifiers. It'll detail exactly how the gain works (sections on gain setting are there too) and if it helps any, your expert salesman is being trumped by a certified master installer and electrical engineer with 15+ years of experience.. for what it's worth.
it is worth one more inch in the ol' e-penis rating.

for what it is worth, IMO, Glasswolf is dead on with this information. A salesman, is only there to sell you what he wants to sell you, not what you want to buy. Your salesman is a total dolt and if he had applied at my shop, I wouldn't have hired him. And this is from a guy who was a salesman, then a salesmanager, and finally a part owner of a shop....for what it is worth..LOL

No thats not to bad, but you could always add in some extra bracing, to beef up the box (might need it since its a prefab) and make the internals smaller.

EDIT............Thanks glass, that part skipped my mind.

not after you figure in the displacement of the sub itself, which will take up room in the box.

lol, nice . . while i have you here answering me, i just bought a new box for my 10's (pre-fab :sad017: ) but i needed one bad . . it has 1.3 cubic feet per chamber, the subs call for 1.125, shouldn't be a big deal huh?

thanks for the website, i'm always looking to expand my knowledge!!! :happy055:

pre-out voltage has NOTHING to do with system volume.
all it affects is signal resolution (how clean or detailed the signal is when it reaches the amplifier.)
2V works just fine. If the system is ANY quieter, it's because your installer(s) don't know how to adjust amplifier input sensitivity (gain) properly.
the gain setting is there specifically to balance the input stage of the amp to whatever the head unit's line voltage is.

wow i was told the exact opposite from a "expert salesman", i'm in class with my notebook ready for notes :thumbsup . . thanks for the info . . back to dvd players tho, i really would like on, i'm looking at a jensen vm9510ts, because my friend has the 9410 and the picture is good and well it cheap . . good choice?
