Why do my subs cut out? #2?

-Why do my subs cut out?

I'm running two solo baric l7 12 inches rated at 750 rms a piece from a t1500 rockford amp which is rated at 1500 rms at 2 ohms (which is what I have them wired at). My subs cut out after about 15-25 minutes of high volume then turn back on after a few minutes of being off. I suspect overheating. Is there anything I can do to make them last longer? Power isn't a problem, I have them hooked up to a separate kinetic 1400 amp batter that's in my trunk with 0 gauge wiring. I have the 1400 amp battery running into my car battery, They are supposed to equalize charge having the alternator charge both. I've had the subs in for about a month but only running on max for about 2 weeks. I made a rack for my amps, having them sitting an inch up and having nothing touching them in my impala trunk. I usually have the seats down to increase air flow but to no prevail. For more details on the sub, http://www.kicker.com/Solo-Baric_L7 . I have the 11 model so those figures are correct. I'm running a ported box made by kicker especially for two of these subs. I never smell anything but the electric smell you get with high-end subs. Also, the kinetic battery has only been in for 2 weeks which is why they only recently have been running on max. Thanks!

Maybe if you would give people the benefit of an hour before posting the question over again you would get more answers to your question.



Saying noone answered last time is a lie.



I answered your last one myself before you even added this new question.
u are either under loading i.e to low impd for amp witch will cause amp to shut down for protection or ur gain is way too high whats the input level on amp if thats too high will also cause shut down if not get a line booster and turn ur gain way down the line booster will make a world of difference
First you need to determine exactly what is causing the subs to cut out. With a meter, test the voltage at the amp before you operate the system. Then when it shuts down. 0.5V difference in the readings could mean significantly less than 12V with the amp operating.



Most amps will go into protection from overheating, low voltage, low impedance, and excessive current conditions. The most probably causes in your case would appear to be overheating or low voltage.



If the alternator doesn't supply enough current to keep both batteries voltage up, either battery will act to reduce the voltage of the other one. In effect, supplying the current to charge the lower voltage battery, while at the same time providing power for the amp.



With trunk installed amps, airflow could also be the problem. If the amp is especially hot when it shuts down, you might consider adding some "forced air cooling". Use a muffin fan to circulate air directly onto the amp heat sink.

Copied and pasted from the other question i answered....

If u give me the chance i can help you...

Do you have that battery hooked up to the alternator?

What is the voice coil setup on the L7



EDIT***

After reading the info i still need to know wether the subwoofer is a Dual 2 or dual 4 OHM

If your smelling anything electrical that is TERRIBLE

If you have some sort of instant messanger im more than happy to help my YIM is Xhellobobx



SECOND EDIT**

My guess is that u have Dual 2 and have it wired to .5 Ohms which that amp isnt stable at so its throwing the amp into protect

If its what im guessing you basically got the wrong amp/sub combo but we can still make it work ;)

And btw

STL Marine WTF are u talking about? Get used to the frequencies? Its buil;d only to play those freq... true there is a break in period where subs get louder after theyve been broken in but WTF are u talking about your definitely wrong.



**Third Edit

Everyone except STL Marine has a knowledgable and highly plausible answer!
