Added ~1000watts rms and only gained .3dbs

[kaimana 10+ year member]

K so i switched out my Fusion 2500.1d amp with a Sundown 3000....I just realized i only gained about .3 dbs..144.8 with the fusion and 145.1 with the Sundown....I also added a 250amp H/O alt too...But I was having problems with my voltage because of how hot it was and i was slamming my sub earlier so the batts weren't fully charged..I was dropping into mid 12v's during the burp..when i used the Fusion i was staying above 13's....But still shouldn't i have had more of a gain than that? I mean i added about 1000 more watts rms...It sounds louder to the ear though too....Maybe i'll try to get it metered again and see how much the voltage was the culprit...

what coils are on the BTL?

you said you were dropping to 12s with the sundown, and only 13 with the fusion

Dual 2 fully loaded...But the old style ones...

Lots of variables there... if the sub was hot actual impedance would also be higher.

rule of thumb is ~3db increase when all things are equal and wattage is doubled. most of that is seen at the back end of the doubled wattage. considering you didn't double your wattage, what are you expecting?

So the fusion I assume only does 2k?

A new box would prolly help you more in your score than Morrrr Powwwaa

The sub wasn't hot but the amp was....It was a hot ass day here in Hawaii and my dumbass friend had put some clothes on the amp...The first time i checked it i got a 144.8...I let my car cool down for about 10mins and my voltage came up to what i posted earlier and got the 145.1...

should've been a 50% increase in power...so increase expected about 1.5db

In theory if he actually doubled his power, but we all know how theory works.

you invest a lot for a .3db gain. I hope it's gonna get better on another day

well that's why i made the thread...basically to see if this was about right...I also figured it would be more because it is audibly louder...

about there...

That was the next thing i was planning on doing but i want to keep it sounding as good as it does on the daily...

Run it through with everything cool and fresh - could be a very large difference for you //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

To be audible at all it would have to be about a dB.

That's what i was figuring..I'll prolly try to get it metered again in a day or two...My voltage usually stays up around 14.5 and barely drops into 13s full tilt but when i got it metered it was mid 13s dropping to mid 12s...

in theory IIRC to gain 3db you have to double your power, or am I off?
