I just got my 2nd level 3 15 and it dosent seem any louder? PLEASE HELP

There are alot of variables that go into that, but yes it is possible. If you want full output from the subs, you need to properly power them. If you went from 1 sub wired at 1 ohm(1200w theoretically) to 2 subs wired a 2 ohm( maybe 300w per sub) You probably arent going to see any gain.

General rule of thumb is double the cone area, add 1.5-3db. But when you cut your power in half when doubling cone area, you cancel that out.

Could it be equally as loud as 1 on 1000-1100 rms the 2 on 500-600?

yes

To get more output you have to increase cone area or power, well you doubled your cone area but if your power is half of what it was then output should be about the same

Hey mister phone thrower I haz no way to get ahold of you!

[dylan117]

Oh alright then so you think when i get them the power they need 900-1200 each that it will be alot louder than before?

Theoretically, yes it should be.

[dylan117]

Ok sweet i was worried that i didnt even need the 2nd sub but looks like its all gonna be what i needed so anyway thanks for all your help guys DC audio FTW as always!

BTW: when you said phone thrower did you mean rusty or me or both lol?

[CJ18]

Phone thrower was at Rusty.

@SGunnem if I twist the one set of positive and negative wires from 1 sub and twist them with the other set of wires from the other sub and hook it into 1 pos and neg amp terminal should it fix anything?

No it won't, it will be exactly the same thing you have now, which is how the amp is designed, save the fact that Hifonics doesn't call it a 0.5Ω stable amp.

You should have the woofers wired in series at the coils and then you should have one cable (two wires, + & -) from each, laid down on the two positive and two negative terminals on the amplifier. This will present the amp with a 2Ω load.

From what it sounds like, you have one sub's coils wired in series and one sub's coil wired in parallel, and with how you have them wired at the amp, that presents it with a 0.8Ω load. That wouldn't cause the amp to go into protect but it would send twice as much power to one sub as the other, which would cause some acoustical cancellation between the two and thus, reduce their output.

Check the wiring at the coils or get pictures and post them here, as was suggested.
