Deciding on power

[bibby 5,000+ posts]

Ok. I was going to go with a 06L715 ported, but the box was gonna be too much trouble to get in the trunk, and too much trouble to build in, and cost to much to have built. so i got an idea from another thread to build two seperate boxes. So now im going with 2 06L710's in seperate boxes ported. and ill combine them, and carpet them once in the trunk.

Now, the dillema. power

2 SX1250.1s @ 1ohm pushing 1300wrms to each sub w/ gains set respectivly (dual 2ohm woofers on each amp)

1 SX1250.1 @ 1ohm pushing 750wrms to per sub with gains respectivly set (2 dual 4 will wire to 1ohm? or dual 2?)

Boxes will be identical w/ 2cuf per box at prolly 34hz. left box port will be on the left, and right box port will be on the right will be the only differences in the boxes.

I also am a firm beleiver of if a sub sais 600/1200 rms/max to give it the max, but respectivley set. listen for distortion.

1 sx1250 should do the trick...i have a kx1200.1 on 2 of o5l7 sealed...and its good to run but m gains have to be really reasonable or probs..i think it would be ok with one of those and runit at 1 ohm

bump.

electrical upgrades will be optima yellow top, big three in knu 0ga and 4 runs of 0ga: 2+ and 2- to the 2 amps, or if one amp, then just one. alt later on.

i think the one amp will wang, but not enough. im used to a l715 ported at 32hz w/900wrms

go for it and tell us how it works out

Input from Polecat? or any other person that has contributed?

 

[bibby 5,000+ posts]

Ok, changed to 2 06L712's with a sx1250.1 per sub running at one ohm. in a 2.5cuf per side enclosure tuned to 33hz

why not a KX/ZX 25001?

 

[bibby 5,000+ posts]

ZX has a red strip, wont match, and im not modifying an 800$ amp. umm, i really like the SX's, ill look into this concept though, 2500's are normally putting out what 2650ish? so 1325per sub, which is close as hell to what the 2 sx would pull. whichever route is cheaper, i like thast idea.

yea, the older KX would do fine, mine, not using it anymore, got a ZX2500 to matych my other two ZX amps //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif did 2660

im getting about the same prices for two refurb kx's as opposed to one 2500, so im probably gonna go with the 2500. what about the power? think its too much for the twelves? i think if done correctly and respectively, it should be badass.
