Respectable db level for my setup?

[osmith 10+ year member]

I have an SA-15 powered by an SAZ 1500 at 2 ohms. I am in the process of building the box to face forward and the front of the box will be about wear the rear seat used to be (it's been removed) I will be sealing everything off from the trunk of course. I am also making the big 3 upgrade with knukonceptz 0 gauge cca as well as running the same wire to my amp for power and ground. After all is said and done what would be a respectable db level for that set up? Not looking to blow anyones mind with it just respectable.

142ish would be real respectable!

Daily on music? 136-146 depending on alot of things. Install it then tell us.

Edit I saw @ 2 ohms. I say 138 then.

not gonna be much considering you'll only be pushing 750 watts rms. recone the woofer to dual 1s and run it at .5 you'll love it more

The goal when I first got the sub was 140 I think if I hit that I'll be happy....for a few hours at least then I'll want more, haha.

Not sure if I know enough to safely run it at the yet....I do plan on adding a second SA-15 at some point, though.

yea but those sundown amps really wake up at .5 ohms,had an old team mate that ran 2 saz 1500s on 2 12s was only doing 146 dbs but on music. we rewired the subs down to .5 each amp and he went up to 150.1 constantly

I'm just worried I'll damage something, haha. And being the poor college kid I am it would probably take a while to fix. How safe is it to push that much power to the SA line?

i think you would be fine considering you will have box rise this will be your best bet .make sure your electrical is good tho

I wish I had some knowledgable guys in my area to help, haha. The people in my town think they know a lot, but the more they talk the more I doubt it.

I've ran my sunddown 2500s strapped at 1 ohm with no problems daily. If I need recones ever, I plan on strapping them at .7 ohms, but I have fairly stout electrical.

i did my saz 4500 at .7 and when i get my other dc 7.5 amp i'll be strapping both dc 7.5 amps at .7 , should be a 154 db or better .did a 152.8 with 2 5ks strapped at .7 earlier this year so we'l see

Those amps really do like .5 ohm, but that is really working it hard and you multiply your risk of breaking something.

Get an extra battery in there before you get the second sub and drop the impedence. 138 to 142 give or take. On the lower end if you want something musical.

How are you all coming up with these dB figures without knowing the vehicle? This is called pulling numbers out of thin air. As it was already stated but apparently ignored, you need to build it then test.

I'm not too far away, but I'd say mid to high 130's.
