You don't need to match the gain on the two amps, the master amp controls the gains and filters on the slave amp so you only have to set one and they both get set the same //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif. No sitting there with meters trying to match output.I do have a dumb question though.... What advantage does strapping offer over running one amp to each subwoofer?
There's a post Jacob (Sundownz) posted on another forum, I use it to demonstrate amp strapping to just about everyone. Very well written, easy to follow, and has pictures. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif.The master amplifier gets the input from the head-unit and a mono RCA from "BR Out" connected.![]()
The slave amplifier ONLY gets "BR In" connected from the master.
ALL controls are handled on the master, setting anything on the slave is not necessary.

This picture should be pretty self explanatory.
* The slave takes the "-" connection(s)
* The master takes the "+" connection(s)
* The "-" terminals of the amps are hooked together.
You don't need to use both sets of "+" on the amps. They are there for flexibility. While you should always connect both "-" terminals on the amps together using large wire as general procedure it is not absolutely necessary to use both sets of "+" terminals. They are connected together internally in parallel.
When strapped the MASTER controls ALL functions of both amps.
True... but on the other hand there are some disadvantages to it. If you accidentally short out the circuit you may take both amps out than just one. Also if you take out a sub you risk hurtting both amps instead of one and there are more subs on the circuit to take out. Now both of these may be rare but they both do happen. So shrugs. But other than the gain setting issue and wiring options there is no benefit to strapping amps. Actually I think it does slightly affect the efficiency although I can't remember if it increases or decreases itYou don't need to match the gain on the two amps, the master amp controls the gains and filters on the slave amp so you only have to set one and they both get set the same //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif.
