1x bridged or 2x stereo?

[jc25t 10+ year member]

Ok to clarify the subject.

I have two sony Xplod 12" subs (4ohm)

1x 4x80wrms, 2x200wrms amp (sony xm-754)

1x 2x150wrms, 1x 370wrms amp (sony xm-1502 i think).

Im still waiting for some components to arrive so i've been running the 4 channel amp bridged to run the 2 subs (200wrms).

Now i thought i better fire up the other amp and sort out how i will run them when i use the 4 channel on components.

Unfortunetely my s*** amp only runs at 4ohm when bridged. So i was just going to run them in stereo. When i tested it, it sounded fine, but then i thought i'd try 1x sub when bridged (370wrms). This actually sounded louded and better than the 2x subs in stereo... whats the go here guys?

Am i better to sell my subs and get one GOOD 12 or 15"? Or am i dreaming and should just run both of them in stereo.....

I also thought maybe i should run the sub off the 4 channel (both sides bridged) and then just run a set of components off the 2 channel?

I dont really wanna sell the amps cos they are both exactly the same and look cool //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Any suggestions? Should i just go buy some low power DVC subs so i can run the amp bridged with the subs in parallel?

By running them bridged, they will be on the same channel and "hitting" at the same time. If you run the subs in stereo, and it's possible that they won't be hitting at the same time, thus they won't sound as good/loud.

Generally you want to run your subs in mono/bridged mode all the time. Unless you're running some midbass subs in stereo for an extreme SQ/imaging install, just run them in MONO.

On the other hand, I have an eD K 12.44 subwoofer (dual 4 ohm) and a custom box for it for sale, I'd like $300 shipped //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

it almost sounds like you got the polarity reversed. Try hooking both subs up again and swap the power and neg wires on the speaker.
