need opinions on one sub or two

Hi guys, been quite awhile since I have posted in here. Been lurking but havent really needed to ask much as usually its already been asked.

Anyway..... My low budget system that came in my winter car needs help. Its kind of my fault for not checking how the previous owner wired everything. But here is the issue,

They had two sony explode 12's 1200w max (350rms) single 4ohm wired to 2ohm and then bridged to mono on a cheap Pyramid amp that was only 4ohm stable bridged (2ohm stereo) Long story short, I set gains and played with bass boost, pushed it hard for about 4 minutes. Burnt the ground circuit on the board. Assume do to the 2ohm load.

Now to my question, my temporary amp that was in my basement is a Rockford Punch 250.2 rated at,

62.5w x 2 @ 4ohms

125w x 2 @ 2ohms

250w x 1 @ 4ohms

Only 4ohm stable bridged.

I have it hooked up in stereo @ 4ohms right now, it helps the sound but would I be better off just powering 1 of the subs bridged @ 250w rms instead of each sub only getting 62.5 watts for a total of 125w?

It seems that logic tells me one sub with twice the power should be louder than half the power split between two. But I may be missing something.

I am buying a new amp but am still looking for the right deal. :)

it probably wont be louder but it should sound cleaner with the sub having the proper power. before you swap amps you need to check the ground location to make sure it is grounded to bare metal and to a good spot on the floor, this is probably part of the reason why your amp kicked the bucket.

I have swapped amps already, and it seems to be working fine, just not much power.

Do you think the ground had more to do with it than overloading the amp at 2ohms?

i think having the ohm load too low did most of the damage but it could have been made worse by a bad ground. i would just check it to be safe unless you want another dead amp. make sure its not rusty or loose and its screwed tightly to the floor and not sandwiched in a seat belt bolt or screwed to the trunk lid like ive seen soo many times

Its grounded to a flange on the inner wheel housing inside the trunk if that makes sense. It has been sanded down to bare metal and looks to be a good connection.

One thing I dont really like about it though that I didnt think of before is they ran the ground from the body to the Cap and from cap to amp. Will that be enough or should I ground it directly to the body?

Also do you think this Rockford amp will hold 2ohms bridged or should I keep it safe and stay at 4ohms?

not the best idea to have anything in the ground path like that cap, give each its own ground and make it as short as possible. i guess the ground you have now is a mile long if its running to a cap and then all the way to the wheel housing. having a long ground can add resistance that makes the amp have to work harder, usually it doesnt cause a problem but if you can make it shorter than why not. you can try to run the amp at 2 ohms but i cant recommend anything other than what it is rated for which is 4 ohm bridged

After my last post I drilled another hole and ran a seperate ground to the amp. Thats usually how I do them, but I figured this set up was working when I bought the car so I didnt really look into it.

I also got a Pioneer GM-D7400M class D mono amp today for next to nothing that was only used for about 6 months before he wrote off his truck and its been sitting on a shelf ever since. Its Rated at 400w rms @ 2ohms.

Is it going to be a decent amp for these two Sony 12's until I replace them?

Keep in mind its a winter car, and im building a whole new system for spring for the other car.
