system ???

just finished my system about a week ago.
I was very happy, at first???

My system is
an Alpine 9813

one PPI 5800 five chanle amp, with QBASS remote.

one Audiobahn 12" sub, dual 4 ohm voice coils.

4 Audiobahn 5X7 mid's with inline X-overs. (3 ohm)

now, it sounded great for about 4-5 days.
then, when I was playing it loud it just shut down, like it was over heated. But I wasn't playing it for that long. Maybe 10 min.

then I shut it off for a minute, or so. Turned it back on and turned it up.
Then the thing starts a very low sub type frequency (20Hz range?) though all the speakers???

I unhooked the RCA's one at a time, and it made no deference??
still the same problem???

It go's from suhting off, to the low sub sound though all the speakers???

Any ideas???
Any info would be great!!!

What shut down the amp or the radio? Both are decent components. Recheck your wiring. It may be a ground to the amp has gotten lose or its not a good enough ground and now the amp is complaining.

The amp is shutting down!

the manual said to run the ground to the batt. for systems over 300 watts? so I did.

And I have a stifning Cap that is grounded too???

I have ran Orion, and PPI for years and never had a problem???
Thanks for the info...

No No No................. Ground the amp as close to the amp as posible. Make the ground wire as short as you can. The amp might be damaged now. Hopefully not. Try shortening the ground wire and let us know if that helped.

make sure you have 4 gauge power/ground cable.

You might already have it, but if you don't, it would help greatly.

keep them the same gauge, don't mix match, you'll get power trapped somewhere...or too much heat build-up.

there's my two cents, spend it wisely...lol

actually it's not a laughing matter, I would start crying if my system was doing what yours is, sorry man...

Where are you getting your 12v from. If you are not using a relay to switch the power or you are not getting it direcly from the battery you may have burned up a switch somewhere.

Yah, I should have gone with my first intuition!!!

I called PPI back, and asked them why there manual say's to go to the Neg. side of the batt. for your ground. And they said that's and old concept, don't do that!!! NICE!!!

I asked why does you manual say to do that???
He said they need to up date it!!!

I'm running a 4 gauge power wire, and ground.
The power, is going to the batt. No relay.
And NOW, the ground is around 10" long.

I no longer have the problem...
