[QUOTE="Prowler573, post: 3080212, member: 561023"] A bit confused over there in Aggie country, are we? That's okay - let's see if we can get you sorted out. [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] Are these 2 speakers, 2 tweeters, and the crossovers you intend to run a component set? Are the crossovers passive units that were supplied with the 4 separate drivers? If so you're going to want to connect the amp to the crossover module. The Xover mod, in turn, will divide the input signal into two separate bands - the highs which will get sent to the tweeter and the rest which will get sent to the midwoofer. If the above isn't applicable then disregard it. If you connect a pair of single voice coil drivers that are both 4 Ohm drivers in parallel like so: [IMG]http://www.rockfordfosgate.com/rftech/woofer_wizard/2_4ohmSVC_2ohm.gif[/IMG] as indicated in the diagram it creates a 2 Ohm load. This will up the amp's output from the 100w per channel it outputs @ 4 Ohms to whatever its rated output is for a 2 Ohm load. If you connect two single voice coil 4 Ohm drivers in series, however, like so: [IMG]http://www.rockfordfosgate.com/rftech/woofer_wizard/2_4ohmSVC_8ohm.gif[/IMG] it yields a nominal 8 Ohm load. This would effectively half your amp's 4 Ohm output or put it around 50w per channel. As far as will that be bad for your amp? No - not unless you drive it into creating clipped output. Clipping is equally bad for both the speaker(s) being powered by that clipped signal and the amp being forced to output it. But assuming a clean signal it won't be bad for the amp. The speakers, however, if not properly crossed over, won't care much for being run full range as they aren't designed for it. You'll want some method of taking all but the highest frequencies out of the signal being fed to the tweets as well as some mechanism for taking the both the highest frequencies [I]and[/I] the lowest frequencies out of the other speaker. I do not know what kind of "other" speaker we're discussing so I cannot do much beside a general recommendation there... [/QUOTE]
