Subs Cutting in and out after about 10-20min

[Zackster]

My setup: Two Pioneer 12" subs with a 1000 watt amp.

I've had this problem with my subs since I installed them and it's quite annoying to say the least... What do you guys think to problem could be?

3 potential issues beside it being fairly bad equipment

1. You have all knobs to the right which is overdriving the amp

2. Ground isn't good

3. The speakers are wired to a lower impedance than the amplifier can handle.

The knobs are definitely not all the way up, I'm not that much of an idiot... I know that the subs are 2 ohms each and I have them bridged to the amp so there is only 2 ohms on the amp. That being said, I don't think it's a heating problem as I originally thought. I 'll check the grounds, but I don't think that's the issue. I have very good and tight connections everywhere. Do you think lowering wire gauge might help?

Can that amp run 2ohm bridges? That's the issue

 

[Zackster]

It reads 2 ohms across the left most and right most + and - Is that not a sign of it working?

Here you go, it says bridgeable

Bridges at 4ohm. That's 2ohm per channel

 

[Zackster]

I'm confused... Both my subs are 2ohms. That means I can't bridge them?

2 SVC 2ohm speakers can wire at 4ohm or 1ohm. What are they at now?
