I'm looking to buy an amp to push my pioneer 3-ways. Heres a link to the speakers that I have...
Pioneer TS-A1670R 3-Way Car Speaker 6.5" 180 Watt

http://i4.ebayimg.com/01/i/02/90/2f/5c_1.JPG

Size: 6 1/2
Sensitivity: 90 dB
Frequency Response: 30-28,000 Hz
Recommended RMS Power: 40W
Peak Power Handling:180W
Impedance: 4 ohms
35 watts rms

Now I'm lookin for a fairly cheap amp that I could get to get some better sound from these puppies. I was thinking of a 200 watt fosgate amp cuz They're fairly cheap on ebay.
Please help!

 

that Fos would be fine.

 

Those 200 watt fosgates on ebay are 25 watts per channel RMS. Your speaker will take more than that. I would go for something a little bigger than that. There are auctions every day for the punch 301x on ebay. They are 40 watts RMS which will sound better than 25. I think the company is called HighDesertAudio or something like that. They go for around one hundred bucks or less because they are refurbished by Rockford Fosgate. That may scare you but it does come with a warranty from RF so it is worth it. Good luck with your system.

 

well my speaker says that it only takes about 35watts RMS...So will the 301x be too much??

 

get something alittle less than 180w like 150w x 4 with a eq will be good.
(an eq is a must I got 2, a 5 band and a 30 band)

 

No, the key to not blowing up speakers is to not make them distort. You can also turn down the gains on the amp a little too.
