Not happy with 1500 watts and multiple subs

[43de 10+ year member]

Well anyways I have a US Amps XT4000D 1500w RMS @ 1 Ohm amp and I have run the following subs on:

2x RE Audio SE12" (d4) - Not that loud... I maxed out @ 112db on a db meter. SQ is sub-par in my opinion.

1x Fi Q 12" with BP Power (d2) - Moves a shitload of air... SQ is better than the RE's... Again not that loud (108db max)

I just ordered an RE Audio MX 12"...

If I don't like that one either I think I'm gonna go with Kicker L7's (//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif) or DD.

What do you guys think?

what the hell... what meter were you using and where was the mic? sure there wasnt anything wrong with it? those 2 se12's should have been at least up around 130 in just any any vehicle with a termlab on the dash... it's the vehicle in your avatar?

somethings definitely not right here.

Right on the dash... then I put the mic about 6" from the port... 120db's... and what's a termlab?

I'm pretty sure there was nothing wrong with it... it was just a normal db meter...

probably bad box

 

[dvrmstrng 5,000+ posts]

bad box, bad meter, how well did you set the settings on your amp, etc?

 

[Super Pickle 10+ year member]

i have a feeling of an underpowered amp with gains not set right and a box to small and not tuned properly

 

[bumpin buick 5,000+ posts]

43de's next question: amps have settings and boxes can be tuned?
