Hello everybody.

This is in a '03 Honda Civic sedan. I am wondering if the amp I have (forgive me, the name doesn't come to me right now...its not one of the big brands) produces 200w x 2 @ 4 ohms and 520w  bridged. The subs are 4 ohm SVC. Currently, the subs are wired one to each channel on the amp, so I am getting the 200 x 2.

A buddy told me to rewire them bridged to get the extra 120w, but I've never done this. How would I go about doing that? I new to all of this so any help is much appreciated. Thank you.

First you need to see if your amp is stable at a 2 ohm load. We need to know the brand and model number.
There is no such thing as free installation!

Yes it is stable at 2 ohm. Its an Audiobahn A2801T. I know, I know, don't flame me to death. Its just for now.

Most amps bridge by hooking up the left positive and right negative speaker leads. Parrallel these to your 2 subs.

Do not do this. This amplifier is not stable to 2 ohm mono. It is only stable to 2 ohm stereo. Your buddies thinking would only be correct if the net load to the amp were 4 ohm in mono. The only way to wire the subs to this amp, in mono, would net either a 2 ohm load wired in parallel and 1000+ watts (which makes the amp smoke uncontrollably and shut down due to heat prematurely) or wire in series and about 280 watts give or take which is far less than you have now.

Top Secret, I can tell you but then my wife will kill me.

Wait a sec  Rob, mabye Im wrong here but genereally speaking an amp wired at 8 ohm mono should produce approx the same amount of power as the same amp wired at 4 ohm stereo, should it not?

Okay, I was a little wrong on the bridged power. I went and found a site that had the specs listed, since I don't have a scanner to show you guys the owners manual:

http://www.cardomain.com/item/ABNA2801T

Its says: Bridged RMS Power @ 4 Ohms: 560W x 1 @ 2 Ohms

I'm confused. It says bridged power at 4ohms, but the it says 560w at 2ohms. I don't get it. I can't make a 4ohm load if I bridge the amp using two 4ohm subs, can I? Wouldn't that yield a 2ohm load on the amp? But after the power rating it says 2ohms...AHHH!!! Somebody explain this for me...I'm lost.

Thank you guys.

That amplifier can be bridged into no lower than a 4-ohm load.  It's 2-ohms stereo stable.

You can't go by every word in either the typical owner's manual or website.  There are too many unknowing hands involved in marketing electronic gear these days.  So you have to use basic knowledge, intuition and common sense in decipering specs.
Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
