So I've been tryin to see just how loud I can get with my current setup but now I'm stuck, anyone care to share any tricks to gaining just that lil extra .x on the mic?

What RCA voltage is your amp getting? H/O alt?

 

[lowriderram_95 10+ year member]

The preouts are 4v but I have some ****** walmart rca's, my voltage never drops below 12 on burps and the setup is gettin taken out of the car in a month or 2 I just wanna get a 50 on the dash outta this car. Doin a 49.7 right now, I know I can do it with a new box I just dont wanna do that

Seats forward, hug the dash, Duct tape, sun visors down, a/c vents set to floor and defrost.....

duct tape where?

Try a balance line driver. It'll give you amp the max RCA voltage. You can find them cheap. RF makes one for like $50 - $60, but you can find other brands for less.

...Why are you recommending this? No amp on the market is going to be preamp-voltage-limited.

beer and burrito's brah! how do you think i hit my score

Sexitime your amp while blasting....try to sweet talk it into more power to subs....say, I will get you a partner to take off some stress down the road....works for me everytime!

It is no wonder I am in debt past my eyelids!

I'm just tryin to hit a 50 before I throw it all in my honda and I dont really wanna build a new box to do it if I dont have to

you should hear mine now man after andrew and i adjusted my amp with his oscope.

Gold plated RCA's, Run your ac for about 15 minutes to get it nice and chilly, rev the shit out of your engine and brace everything you can (I wouldn't recommend duct tape but it couldn't hurt). Try to brace your door panels to keep them from vibrating.

Also, if you have a buddy, have him grip the outside of the car on the passenger side door to keep that side from vibrating.

That said, I don't believe you'll gain much.

EDIT:This is ofcourse if you have found your peak resonant frequency and optimum box placement.

Turn your box differently. Move it around the vehicle at different angles.

 

[smgreen20 10+ year member]

Buck hit on my thought, What are you tuned to? Go higher, 65ish Hz. Subs are more efficient there.

 

[Louisiana_CRX 5,000+ posts]

hmmm...you can get louder with more subs or a bigger amp...if you double cone area good for 3dbs or if you double amp power good for 3dbs...if you do both you'll gain 6dbs... //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Altering enclosure tuning does not affect speaker efficiency. The idea behind higher tuning is to align the resonant freq of your vehicle with the peak output freq of your box/sub.

You may realize this, but your post was a bit misleading.

 

[smgreen20 10+ year member]

Yes/no. They ARE more efficient at the higher freqs, but yes I forgot that the guy I know that used to compete was tuned to his vans resonant freq of 67Hz. Some know him, some don't... Crazy "dB Dave" Jennings.

No, they AREN'T. A speaker's efficiency does not change based on its environment (including enclosure or vehicle). You can alter the over all efficiency of the system (speaker + enclosure + environment), but nothing you do, short of ripping into the speaker itself and altering its design, will change its efficiency.

And if your theory that subs are more efficient at higher freqs was true, then I guess a subwoofer would be hella efficient at 20khz.

I'm not going to argue with you on this, but I'm sure Dave knows more about this then both of us, and it is easier to get more SPL out of a system at a higher freq vs a lower freq (with in the subs capability, 20k Hz, come on, you know I'm not that stupid), even if both freqs are to the vehicles resonant freq. Example: 33Hz, 66Hz, 132 Hz.... would all be resonant freqs. for xx vehicle.

How many resonant frequencies do you think your vehicle has?

And 'getting more SPL out of your system at higher tunings' is not the same as your original comment that subwoofers are more efficient at higher freqs. Go plot out the freq curve of several subwoofers in sealed boxes using WinISD, which ignores environmental factors like cabin gain, and then come back and tell us what you saw. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
