question about strapping and ohms

me and my friend were having a discussion on strapping amps and we both came to the conclusion that we dont know shit about how that affects the final ohm load.

i was under the impression that it halfs the ohm load, so if i had two d2's wired to .5ohm each amp would be seeing .25ohm. am i wrong?

The only way to delete your SMD account is for you crawl to steve meades door step on your knees and pleade for his forgiveness and acceptance to be released...He will either grant your wishes.....or choke you with a large piece of 0 gauge and electrocute you by hooking up a solid gold DC 12k at 0.000001 ohm and 10000 volts to your eye sockets and blow your head apart

You guys act like you have never clogged a toilet and ran around the bathroom frantically hoping it don't overflow.

Your correct. Try not to strap at .5 nominal .... That's pretty low for most people

Strapping 2 amps is exacty the same as bridging a single 2ch amp into a mono amp.

When two amps are strapped, one amp is out of phase with the other thusly doubling your final voltage across the load.

Same rules apply as they would when bridging the 2ch amp.

The lowest rated impedance of the channel or amp should be doubled when bridging/strapping.

Example 2ch amp specs:

100W x 2 @ 4ohms

200W x 2 @ 2ohms (lowest)

400W x 1 @ 4ohms (lowest)

yeah i wouldnt personally strap an amp that low but there is no telling what he would do. i think he wanted to do two aq2200's on 4 15" hdc3 d2's
