Basically any 4 channel amp that you like that provides at least 40 watts rms per channel.

They're hard to find, but I've been happy with my two US Acoustics amps. Clean power, and they never get hot.

1. You should have written intend instead of attend, they're two different words.
2. For your banging *** system, do you want SPL or SQL? Sound Pressure Level (SPL) is what's used in DB Drag competitions to try and get the highest decibel level out of your car. Some symptoms are ear bleeds and hearing loss at the age of 30. Sound Quality Level (SQL) is what these idiots wish they had gotten into but usually by this time it's too late. It's basically quality of sound instead of how hard it hits. So the bass is usually turned down a bit to be able to hear the words and other instruments in the song. This is what I would recommend.
3. Your amplifiers come in different classes, (A, A/B, D) where D is a proper amplifier and the Sony Xplod stuff is A.
4. The RMS power of the amplifier should match the RMS power of the speakers, and the channels of the amplifier should match the number of speakers.

Then you're done. Don't buy based on brand names, everyone's too obsessed with brand names. Buy based on the points I've outlined to properly match an amplifier for your speakers and you won't regret it. Although you will find it's the Boston Acoustics/Rockford Fosgates/Alpines that you'll end up with by doing this anyway.

EDIT - my rambling of SPL/SQL can be ignored, forgot you were talking about speakers!

I'm not going to jump on you every time you make a spelling mistake but I thought it would be pretty embarrassing for you if you were in a meeting with someone and used attend......I'd look at the guy next to me like, "Did he just say attend?" Anyway, just thought you'd want to know.

So yes, a 4 channel amplifier with RMS per channel equal to that of each speaker. Hopefully the RMS on the fronts you bought are the same as the rear, plus you hopefully have a crossover kit (or one built in) as well. Other than that make sure it's a D class amplifier and hooked up with good 4 gauge wiring. Then upgrade the big three under your hood as well.
