Fi q no louder on new amp!!!???

[Blinkrazy 10+ year member]

Had my q on my rockford fosgate p400.2 in my ~4^3 box tuned at ~28hz it hit pretty good and was much louder than my previous w3,

today hooked it to my new nine.1 and tuned it, but it isn't that much louder, like barley if at all louder, the only diff is that i get nasty voltage drop now...

so what do you think the lf, phase, and tuning knobs,(besides gain and bass) b/c i use a dmm should be set at?

wat power did u give to the sub with that RF and how much power are u giving it with the ED

 

[pjvoc 10+ year member]

check the sub wiring, and grounds, nasty voltage drop isnt good, could mean bad ground or maybe you wired the sub wrong

nine should be giving around 1200 and rockford is quoted at 400x1 at 4ohms

ground is good, just the trailblazer electral is shittyy so ill need to do big three

so any ideas on why the rf was basically just as loud?

box?

well you trippled the power so it should be much louder either you dont have the sub wired right or the gain set right

or bad electrical and the amp isnt putting out the power you think it is, or the box

im calling bad electrical

it is because the RF is underrated and the eD does rated. So if you think about it, you're not making that much of a jump in power to make a difference. And the voltage drop is because the eD is inefficient

so big 3 and its better?

box= 4.057 cuft with 2 3inch aero's tuned to ~28 hz

 

[dragnix 5,000+ posts]

a new amp might make it better

Sounds like you're pulling more then what your electrical can put out. With serious voltage dips, you won't see close to what the amp puts out. Dmm @ the amp - calculate - and tell how many watts its putting out. Measure at full tilt when the voltage is the lowest / highest demand from the amp.

u need more port area like 3 4" aeros
