Subwoofer/amp cutting out

[em2tk]

I checked all the wiring, nothing is faulty.

But when I turn the subs up too loud, the amp cuts off into protect mode untill i turn the volume down a little bit.

I know the amp should be able to handle it

I have a 2510d2 digital design subwoofer, powered by a Crossfire xp1400D amp.

I have the sub ran in parallel to one ohm.

Thing is when I use 2 of the subs (same subs) 2510d2's ran in series, the amp doesn't cut off and that should be drawing more power than the single sub in 1 ohm. Any advice?

how are your gains set?

No sir. Two D2 subs wired in series produce an 8 ohm load, resulting in less power produced and less strain overall. Wired in parallel/series you can get a 2 ohm load, still less draw than one. Wired parallel you get a .5ohm load, which I guarantee will make your amp cutoff right now. Answer 05Fronty's question about gain setting. What size wire are you using and what, if any, other electrical upgrades have you done?

I have the gain set all the way up, I'm using 4 gauge to the back which I have a deep cycle marine battery, 4 gauge power to amp, ground is 4 gauge bolted to battery and to the frame, split to the amp, speaker wires are 10 gauge

Bold=problem

But why won't it cut out when I have both subs connecting, with the gain all the way up?

I've also tried turning the gain down on the amp, if I turn the bass up on the headunit, they still cut out... The amplifier should be one ohm stable, which is what my subwoofer is wired to right now as a single.

Both subs together is too much bass for me.. I can barely drive due to shaky eye vision

Both subs connected is giving you a higher ohm load which results in less power the amp is trying to produce, which means it needs less electricity to do so. Therefore it's fine in that configuration. I think the "two subs=shaky eye vision" is simply a figment of your imagination. You need to measure voltage at the amp and make sure it's being fed the power it needs. Then you need to learn how to set your gains properly.
