SQ/ SPL system

forbidden - the sub amp was the reference series 1100.1  - its on the website

velocity motors- i am not looking for spl...im leaning more towards sq than spl...and i never thought about actually competing ( im only 18 and this is for my personal car) haha but now that u mention it i guess i could compete in sql or something with the setup

bangbang- spl = sound pressure level and sq= sound quality

That's what I thought but your original post was a little off on the model number. It's best to be sure. Your amp is stable to 2 ohm mono and it is a beauty. I would use two single voice coil Eclipse aluminum subs, model# SW8122.4 or SW8102.4, a pair of 12" or a pair of 10". They both work amazing in small sealed boxes of as small as .5 cu.ft but start to shine when they reach 1.0 cu.ft. I personally like a 1.25 cu.ft sealed enclosure for each sub. These subs are capable of a good amount of SPL, care must be taken with the construction of the box, if you can double up on the front surface of the box, the baffle board, as these subs can easily rip out of 3/4" mdf due to their weight, the motion of the vehicle and the pressures that are generated inside of the box. Make real sure that box is mounted down real solid, a box that can vibrate or move will bleed off energy that should be coming at you in the form of sound.

Should you continue on this path you for sure could be competing and I would think that you would do quite well. I would choose the 12's over 10's if I had the room, even though the 10's can play the same deep bass and overall tones that the 12's can, the 12's can play the notes will a little more authority if asked to do so. Box size is the same for the 10's and 12's and the price is not drastically different bewteen the two sizes. Go with what will fit the vehicle or your budget. I personally use two of the 10's in my 93 MR2, if I could have fit the 12's I definitely would have.

sorry if this is an extremely stupid question but, only being 18 and this being my first aftermarket car system I have to ask it,

if u suggest runnning two subs then dont i need 2 of the 1100.1's ......or can u hook up 2 subs to one of these amps?

thanks

id also like to mention that this is a kick ass forum...u guys are so fast in responding and posting....thanks for all the help so far guys

No question is stupid unless you asked it before and then didn't listen...so it's not stupid or even unusual.  You can wire subs together before they are hooked up to the amp.  A box with 2 or 4 subs in it are all connected together, and the connections they have determine the total impedence.  That total is referred to as a "load", and that load is connected to the amp.  Rockford has some good references to wiring here.

whoops....u already told me that that is the case
