i have all the stuff i need for my system except an amp to power my speakers. i need a 4 channel amp so when i get rear speakers i can power them off of it. i got CDT cl61a components for the front. i look on ebay for the 2 amps GoghUA
reccommend but came up empty.

 

I went to look for a price on that amp, and I just realized the the JBL I reccomended for you wouldn't be the best way to go. That JBL is rated 80 x 4... but at 2 ohms. The speakers are 4 ohms.
You will need to look for something that puts around 90 watts at 4 ohms. I know the US Acoustics USX2100 puts of 100 x 4 at 4 ohms. It is only $99 brand new at The Zeb. Those CDTs can probably handle 100 x 4. But don't run them that high initially, they will need a break in period. I am sure you can look around some more and find some other options if you don't want to go with the US Acoustics. Just be sure to look for 90 x 4 at 4 ohms not 2 ohms. You can vary on the wattage by a little (I am just saying 90 because that is the reccomended power from CDT) the ohm load is what is important.

Good luck

 

is that amp on the zeb a 4 channel amp? i need a 4 channel one to power my rear speakers.

 

Oops! Sorry man, I'm just being an idiot lately.

Anyway, just look around for a 4 channel amp that is rated around 90 watts per channel at 4 ohms.

This is a good budget amp... http://www.lanzar.com/itempage.asp?model=VIBE418
