  1. assuming that whatever device he used was able to accurately measure the 3100s, it may be possible that the optima is pulling down the 3100s...and those 2 batteries could be what's holding up your system. This is also assuming the 2 XS are wired from your optima and not straight from the alternator. I would take the optima out and leave just the 3100s in and see if they return to normal.

    Personally I wouldn't run optima batteries for our applications. Others say they are fine, but this is only my opinion.

    yea i was hearing that too that the batts were stressing more, my deka intimidator just came in the mail today, but i am not sure if i should hook it all up since the xs powers may be bad

  2. Hey everyone. I have 3 batteries in my system (Optima yellowtop, 2 xs d3100s) with a dcpower 270 xp alt powering a sundown 4500 at .5 ohms with 1000+ watts of mids/high power. Full tilt @ 2k rpm, i drop to arond 12.4-12.8 volts depending on the music. Well, i just got my car serviced at a dealership last week and they said that my optima battery was dead, but all 3 batteries were wired together, so I was wondering how they came to that conclusion. A buddy mechanic of mine decided we should test all the batteries with a device that measures cca. After doing the test, the optima battery had 32 cca (its over 3 years old), and the car wouldnt even start so it was clearly dead, but the xs batteries (about 8 months old) showed around 370 cca on one and 380 cca on the other when it should be around 1300. He claims that the device used may not be accurate to test the d3100 and to get it carbon load tested, but nowhere within 80 miles from where i live will do that.

    My question is, why would the voltage be good on 1 dead battery and 2 bad batteries, assuming the device is correct. Any input would be great

  3. My amp just got back from dbr for a mosfet repair and the back plate seems to rattle violently still, even though they said they used loctite on all the screws. It flexes about 1/8th of an inch, is this something to be concerned about to damage anything? Ive tried alot of methods (stuffed towels in corners of amp, mounted dense rubber on mounts to absorb vibration) and minimized the rattling a little but it still flexes, especially on high notes. attached is a pic on how its mounted. Its mounted on birch wood on back of enclosure, 3 inches away from back of the trunk so im limited on space

  4. Excessive Amperage 200 Amp Alt for 1996-2003 nissan maxima, or 1996-2001 infiniti I30, or can be custom fitted to most vehicles via bracket. $240 shipped, paypal as money owed to [email protected]. In excellent condition, did over 140a at idle at over 200a at 2000 rpm under 2 saz 2500s at 2 ohm strapped and only 2 batteries, never dropped below 12.4 (until i ran an saz 4500 at .5 ohms which is why i am selling, dropped to 11.8 full tilt).
