My speakers are 2 ohms my amp is a rockford fosgate pinch 401s 1200 can I bridge my speakers serise to make them 4 ohm

If the wires were touching then the amp overworked itself into a early grave..What happends when they touch is the amp goes from seeing a 4 ohm load to seeing a 0 ohm load. You can imagine why this would be bad for a amp...usually the amp should shut off to protect from damage and I would assume that Rockford would. Right now im having a similar problem..I suggest your call rockford and ask to talk to a technical advisor ( the name escapes me) and ask him what he thinks.

that amp should work fine with those speakers,just make sure that they(speakers)are wired for 2 ohms.at 500-600watts coming from amp, you should be getting 250-300 watts per speaker,just dont crank your gain too high on the amp.

Ok.. Bridge the two sub into 4ohm than bridge to amp.


So. this how it goes.

sub1 + -
to      | |
sub2 - +
=      4ohm
       

           From Sub
                Two
            -          +  
            |           |
amp (L) - + (R)- +


This will use the full potiental of RF 800a2 amp. I believe it like 1153 watts max out.

it is really hard on an amp to run it below recommendation or specs and most audio companies won't warranty if they catch wind. but i have not seen an amp last long or operate without cutting out when you do this.

if your sub will handle it, bridging it will give you more power. The best thing to do is to find out how much power the amp puts out ( RMS ) and if it is in your power handling range bridge it. It sounds better and gives you a harder punch because of more power.
