If the box is linear and musical that's a very respectable #. If you want a big number tune high, huge aero-port and more power. (I'd suggest building a whole separate box for that since the box that'll get you high 140's will not sound nice with music)

Question to the part in red. Are the speakers disconnected when you run the setup non strapped?? Also do you have pin connectors on the end of the speaker wire?? Cause my ESX 60.4 did a similar sound and all it was was the set screw was destorying the wire. So i added pin connectors and the sound vanished. LOL, yes speaker connected, I meant removed the - to - wires. and the RCA between master out and slave in. Hooking up speaker to either amp. No pin connectors, but again, just one amp or the other and no noise. Also no isses with protect mode as others mentioned could be a problem, output is fantastic. Again, will test more in the daylight tomorrow.

Both amps are dead quiet when not strapped. Both grounds straight to the same negative battery terminal <3ft from the amps on 1/0 guage. Will play more tomorrow in the daylight.

Ehh, not sure. It is possible if you want to try, but I would not suggest it. Would probably be best to just get an entire new top assembly. its worth a shot, and if i do ill just pick up a new top assembly. could this be build into like a 10 since i already have a spare 10" basket here? That I am not sure of, but I don't see why not. I would suggest emailing Mach5 to find out any specifics in terms of rebuilding. It is a 2" coil motor, but as for specs, I don't have them. ok ill decide that after i try to fix the sub. and thanks for the input cause im going to pick this up just to mess around with it. Try some JB Weld. I tore an aluminum cone apart and mended it with some and it's holding up very well to some serious punishment.

Well,As I mentioned here. I did get a chance to hook up the second SAZ 3000D today. I measured a nominal 3 ohm load with each coil series and each woofer parallel to eachother. Anyway in theory there would be something to gain (stability if nothing else) running these subs strapped to the 3 ohm load. Initial testing reveals noticeable gain in output and in SQ. BUT there's a nasty engine noise from the subs now. Seems to not be effected by the gain. Both amps connected to the same battery (in the trunk) with <3ft lengths of #1/0 guage. resting at 12.6V car off (total 3 batteries in car). RCA is a 1.5ft piece of high qualtiy patch cable. Now if I ONLY remove the speaker leads, and move the main source RCA to either amp both run dead quiet. Any ideas of a fix for this? I would really like to keep the pair of these for the extra power and to run them in a more stable impedence. I'm also planning to get a 3 ohm TC LMS driver that I would like to have these two strapped into for playing around with so being able to drive 4KWish into a 3 ohm load (WITHOUT noise) is now my goal.

WOW, lot of man hours into this job! I have a few pair of those vifa tweeters they do sound particularly nice on-axis (off axis...not so hot) definitley picked the best spot for them IMO.

X3 I like single driver personally, pair of 12's and single 15 is about the same.....damn I really wish I had a hatchback (

Odds are if you're listening to music over time the amp would be in the 1-2KW range anyway. IF you like to drive around playing sine waves at 14KW you've got some problems and really good luck with the charging system that'll supply 1,000 amperes at 18V for more than a second or two. I also suspect you wouldn't be able to hear the difference between 14KW and 10 KW without testing equipment. There's a pretty good chart of what wire is reccomended to carry for current at www.weldingsupply.com. Again, you're listening to music (supposedly?) which is dynamic in nature on a system that very rarely would need or even be able to draw max current.
