what do you guys recommend for a 600watt sub? my amp can push 300watts x 2 at 2 ohms or 600watts bridged so Im looking to upgrade my 300watt pioneer sub. The rockford fosgate t112d4 looks like a perfect sub, any comments on it?

also, what's SQ and SPL? from what i read on here, SPL is targeted more toward competition and SQ is used for quality audio output.

 

SQ and SPL are 2 different types of competition.....

SQ is Sound Quality competition
SPL is Sound Pressure Level competition.....

SQ is for judging accuracy in reproduction of music/recordings...

SPL is how loud your subs are.....


if your amp can handle a 2ohm bridged load, then yes, you've selected the correct sub..... if it can only handle a 4ohm bridged load, then you'll need a dual 2ohm sub instead of the dual 4ohm in the link above....

 

Is RF Power considered SQ or SPL?

 

it's more of a mix, alot of people call it SQL..... they wouldn't likely be used in strict SQ competition but will give a good sound.....

 

Hmm, anyone recommend other SQ 600watt 12" subs?

 

strict SQ probably isn't going to be 600w.....or 12"......

in SQ, you barely even hear the sub.....all it does is low frequency that the front stage can't achieve......Ideally, you'd mount the small subs in the front of the vehicle.....unless you're going to be competing, this Fosgate sub will work just fine for ya....

 

ha ha alllright (watching family guy, <3 quagmier)

Being a car audio fanatic for about a year now, I would have to say right now that the the 12" RL-P from Soundsplinter.com is a top notch SQL driver delivering top notch SQ and SPL. 600 Watts would be perfect for it in the correct enclosure. You installation is actually more important than your sub.

 

Is there anything I should look for or use for my sub installation?

 

make sure all wires are connected securely and properly, make sure all wires are free from being pinched or torn into..... make sure the enclosure you use is within the subwoofer specifications.... that kind of thing...

 

Its best not to get Pre-Fab Enclosures as they are not sealed very well and not worth it.
