I accidentally cracked the cone of my Fi Q12 not paying attention to having cargo secured properly.  Anyhow, It's been replaced but once I put it back together, the woofer practically has zero output and what's there sounds really distorted.  I double checked my ground and it reads .2 ohms.  Power to the amp is good (reads 12.65V on battery).  Reading across the woofer coils is good (1.2ohms).  I swapped out a new RCA thinking maybe that's it and still the same thing.  Messing around with the head unit and amp settings make no difference.  I even replaced the woofer completely and it also does the same thing.  I've got a Sun Down SAZ-1500D V.3 amp I ordered back in October... does it sound like it's the culprit?  I didn't change or move anything in the system initially other than pulling out the woofer and recone. 

 

Here's my setup.

 

2007 Trailblazer SS

0 Gauge wiring

Big 3 (0 gauge used with 3 grounds vice 2)

Die Hard Platinum Battery

Factory Unit using a PAC-OEM adapter

Monster RCA cable

Sun Down Audio SAZ-1500D V.3

Ascendant Audio Havoc 12" currently installed

 

 

Any insight would be appreciated! 

 

you wire the sub's coils out of phase?  it would still read the same resistance but wouldn't produce sound. 

So you tried a different sub and still had issues with output?

 

Measure the voltage output from the amp and see what it reads.

missed that he tried another speaker. disregard my post OP

 

unless you wired both subs wrong

pull the sub check your wiring again.. it would like your shorting out the coils.

Thanks for the quick replies.  I rushed doing the swap and definitely was off wiring sub side.   Got it back together and all is well! Thanks for the help!
