I was forced into an upgrade... which combination should I go with?

I am thinking about it again and I dont think I can wire my DUAL 4 sub to get a final impedance of 4ohm. I was thinking, if the amp can do 350W x 1 @ 4ohm bridged, wouldnt that equate to ~175W x 1 @ 8ohm bridged?

Yuppers.

Thats what I would do.

I thought you were going to wire each coil to a channel on the amp.

Would that have given me a 4ohm load? I did some searching and no one has said to have been able to wire a dual 4 ohm sub for a final impedance of 4ohm.

No you can't wire a dual 4 ohm woofer for a final load of 4 ohms.

And I wouldn't wire the coils to each side of the amp UNLESS your running a dual mono and can match your outputs.

When I set the output on my Eclipse deck, and the input and output on my DQS there was some pretty big differences in output between right and left. Especially with the DQS,

Add in a regular 2 channel amp with one gain adjustment, and now the difference is even bigger. If you were to hook a dual voice coil sub up the coils would see different voltages, and start fighting each other.

If your running a dual mono or 2 different amps (as long as your input is mono) you can match the outputs so the coils work together.

As for your original question about overpowering your subs, I wouldn't worry about it. Set the gain how you would any other day and back it down a little to match the front stage. As long as you don't run the amp into clipping a little overhead isn't going to hurt.

On a side note, I got both my amp and subs in. I have been torturted for the past week without any bass so I decided to throw in a new sub in my old enclosure with my new amp. I wired up the dual 4 ohm in an 8ohm final configuration and bridged the amp, giving me 175W x 1 @ 8ohm. This will satisfy my needs until I finish the box and install the other woofer

So I went out at 12 midnight the other night to install the new amp and temporary setup of 1 of the 2 RE subs in my old enclosure. Let me tell you, this sub sounds so much better than the old RE sub I had in there, and this is ~125W less power! I cant wait to hear 2 of them with 375W of power in my own enclosure!
