I'm not finding that amp on their site. Is this an older one, or something from an internet marketer? According to your specs, it's only a 2 channel amp. I would be looking for a 4 channel amp that makes at least 80 watts per channel X4 at 4 ohms.

its an older amp, one of my friends he is willing to give me for a great price, i know 4 channel 80W would be ideal, but this might be the best deal i have right now, couldnt i just piggy back them 2 speakers/channel

YOU COULD BUT THE AMP WILL NOT LAST LONG. BETTER OFF BUYING A 4 X 100 AMP.

I can't answer the question without knowing what the ohm load of the speakers are.
If they are 8ohms you can parallel two and two to get 4 ohms per side and use the stereo amp.

I agree completely. The one thing you want to sound good with no problems -besides your engine- is your stereo. Now days you can buy alot of amp for very little money. I just purchase yesterday 3 complete sets of components (Polk Audio) 2 amps, 2 subs and all the necessary wiring. A good amp is an Alpine V Series 450 4 channel. Would make those speakers sound great, forget about the max and focus on the RMS wattage.

Don't buy a 4 by 100 watt amp for the sheer reason of presenting separate loads.
If you do listen to people who give speaker matching advice without knowing what the specs of your speakers really are... at least get one with an input combining feature so you don't have to have rca Y cables just because people want you to have a 4 channel amp to drive a two channel system.

How anyone can predict the life expectancy of your amp without knowing how much resistance the amp is seeing in your specific application is just guessing.

The game changes with every change in speaker impedance.

Ok... if the speakers are 4 ohm you can run them in series, get 200 watt max divided by two speakers equals 100watt max into each 6 by 9.

if you want more amp you can always get a bigger two channel.

I would recommend a four channel amp if all four of your 6 by 9s are NOT matched.
