david Silver Member Username: Davidt487 Texas Post Number: 133 Registered: Dec-07	Posted on Wednesday, June 18, 2008 - 20:28 GMT Well I got it all installed in the impala and I'm not thrilled with the way it sounds. I have a 12" sx in my truck and its sounds great This 15 is almost popping on sharp notes I've change the direction of the box but no luck. I tuned it a little lower than my 12 but this 15 is in a box to specs 4 cu ft @ 34 hz. any ideas????

Gently turn the sub up free air no where near what you would in the box just to get some movement out of it but not enough to bottom it out. You may have a mechanical issue. I had a couple of them and absolutely loved them, great subs... Polo.

I'm assuming electrical issues? Could be a bad connection somewhere too. Does your sub/amp ever feel warm or hot? Does it ever shut off periodically?

I was getting some bad voltage drop idling with the AC on but now its staying 14ish all the time. Thanks Polo I'll try that and see if there are any issues.
