Whats the best way to make your system louder?

[ThumpinJP]

I have two 15'' Directed subwoofers with a 1000watt sony amp an i run it off a batterie an its loud an all but i want it louder an i dont want to spend anymore money on it an i was wondering if i can tweek it or something just to give it a little more power?

while it's also the easiest way to cook your subs, turning the gain up on the amp will make them louder at a given input level. don't do this - assuming you've properly set up the subs, turning the gains up is a very bad idea. barring that, ive got no idea how to up spl without spending some money. my bad.

ps. i told u not to do it to cover my ass in case you do blow up your stuff. go for it if you wish, but u may want to wait for another couple responses first.

no money=no louder
you can turn up the gains on your amp if youre careful
if youre not careful, youll blow your subs and your amp, but then you can replace your sony stuff with real car audio:D

YOu dont say what kind of Box they are in...but minimal cost...if they are sealed..go ported. also..if they face foward towards you..turn them towards the back

other then that... like what cody said...no money=no louder

might i ask what the difference is if the sub(s) are facing you or your trunk?

[sntnsupermen131]

bass has to reflect off something to hear it, im not sure about the exact physics, vince or thoms can probably better answer this question than i can

a 20 Hz soundwave is about 150 metres long, so it can't be that the wave needs to expand first. the back-pressure from a nearby solid object would hinder the physical movement of the cone (like the backpressure of a turbocharger); and there needs to be some air in front of the driver to vibrate to produce any sound

It is called corner loading that causes a 3 db gain for facing them backward if in a trunk or hatch. The same happens in a house with a sub in a corner. You get 1.5 db from each wall that it sits next to. It has less to do with wavelength than it does with cabin pressurizing then releasing foward.

You get a similar 3 db gain by porting a cabinet instead of using a sealed box, but you have to make sure the box and ports are sized (tuned) properly to take advantage of the cabin curve frequency response. Porting the box reduces power handling of the drivers though, so be careful.
