2 amps get alot more power

[partyboyy769]

i have 2 audiobahn 500w 1000max peek 12s(awc12t) and a rockford amp(p3001). The subs hit pretty hard now but if i get another p3001 and use one amp for each sub will it be worth the money, and will it hit alot better than it does now? i can find them for about 130$. Tnx

If the true power is going to be the same to each sub as it is right now, it isn't going to make it harder. With two RFs, it will sound a bit cleaner though.

EXPLAIN????..I am powering 2 subs with 1 ARC amp per sub..so you are telling me it will be cleaner..I have heard getting the 2 subs to hit simoltaneously is tricky..do you mean that the power will be cleaner because of 2 power sources thus the subs will hit cleaner??

please explain I am curious

whoa bigun....

he's doubling his power....in theory, there are two ways to increase spl to the point u hear it, 3db.....one is doubling the surface area, the other is doubling of power....

he's keeping the same amount of sub, but is adding a second amp of equal power to the first..hence doubling...

so in theory party...u should experience a increase of spl of 3 db..or twice as loud as u are now....

the only catch..is make sure u are matching ur impedence correctly...if not, adding the second amp will do nothing but add a current draw to ur electrical system..

also, depression is also correct...running two amps means setting two gains...and if they aren't close, ur sytem will/could sound like ***, due to one sub/amp peaking before the other...hence distortion..

hope that helps....

to help clarify..what is the vc configuration on ur subs? what are the specs on the amp? with those, a more accurate anwer will be possible..

Sorry to jump in on this thread..I gotta pull the other specs out of the manuals but here are these initial specs, are they of any use to what I am looking at? I am being instructed that because of the GAIN setting issue while powering 2 sub seperately..that my only alternative is going to be to set the gains at "0" on both amps????that sounds like a bad deal..what does that mean..what does it elimintate in my flexibility and sound If I set both gains at "0" to gaurentee they are both set the EXACT same??

3db is not twice as loud. 6db is twice as loud, but due to the inaccuracy of human hearing you really need about 10db to *sound* twice as loud.

ok,ok...

a 10 db gain in the real world is twice as loud....but do to transient response and a bunch of technical stuff, in car audio 3 db is considered twice as loud due to the fact that that is about the point a person hears a difference..

here..this might help settle a little bit of it...it shows we are both correct in a manner of speaking..

DEPRESSION...setting both gains at zero will indeed make sure they are almost equal...but u can set them with a dmm, oscillscope or rta. go to the site in the above screenshot, there should be a section about setting gains..also check jmacs tutorial..or jlaudio's tutorial...
