Help choosing an amp for my speakers.

[01rednavigator]

I have installed many stereos and speakers in my cars but I have never done an amp install, I just need help picking out an amp to match my speakers.

I am running four Pioneer TS-D6802R 6x8 2-way speakers connected to a Pioneer AVH-P4300DVD in my 2001 Navigator. I want to get an amp for the speakers so they sound better, but I am not sure what amp to get or how powerful the amp should be and what brands I should be looking at. This is the power rating on the speakers:

◦Peak: 520 watts per pair / 260 watts each

◦RMS: 120 watts per pair / 60 watts each

If these are co-ax speakers then I'm willing to bet your not going to need as large of an amp as you think you do, most likely those numbers are over-rated, find a 4ch amp that does about 100rms per channel @4ohms and I think you'll have plenty of power on them.

perfect rms@ 4ohm but he would need two of them.

This would be a good starter amp with a little head room, and a 2yr warranty BNIB

The speakers are co-ax, since the speakers are 60 watts rms each wouldn't 100 watts rms be to much? I was thinking more like 60-80 watts rms for the amp. Everything I have read says match your amp to the rms of the speakers. I dont want to burn up the speakers!

That amp will be fine..100 rms @14.4v and at 100%volume,,You wont be there at voltage, nor you would want to max the gain out on the amp,so it will be fine ..start out at low gain, and work your way up till you distort at max volume on radio knob, and turn it down a bit, and you will be fine ..Good price and warranty too on the amp for Brand new

This is usually suggested when a noob wants the forum boner sub of the day and 3,000watts of power on a stock electrical system. As far as good sq , you desire headroom in a system. Think of this as reserve power on demand. You could probably run a 200 watt/ch amp on the speakers you have and not blow them as long as you did not play full tilt hours on end. At moderate listening levels say, 1/2 vol. your system might actually be using 1/8 to 1/2 the power, maybe spikes here and there. Obviously you are not going to be listening to dubstep, since that type of music requires energy your speakers could not reproduce with authority anyways. I would start looking at 100w/ch for a good sounding system capable of good music reproduction at elevated levels. The key is to avoid clipping your speakers by trying to make the amp do more than it can. Keep the signal clean and have power available to truly enjoy your system. I do a lot of Pro Audio and it is basically common rule of thumb to use amplification that equals 1.5-2x the speakers rms ratings.....for the purpose of Headroom, And I do not blow speakers by keeping enough power on tap that I can safely avoid clipping.

AMEN!! Lol..Thank you sir..well put:santa:

To the OP,

Do not obsess with the RMS power ratings. Any amp with an honest rating of 50-60watts RMS or more should work fine. If need a specific recommendation, I'd look into Alpine MRX F35, PPI Phantom P900.4, PPI Black Ice, PPI Sedona, or Boston Acoustics GT-475 (not the GTA series full range).

I wouldn't recommend MB Quart stuff as a good beginner amp. What's a beginner amp anyways? An amp you will replace once you learn how crappy it is? I saw a test of 2-channel FX amp in a russian magazine. I believe it was rated for 2x60watts RMS at 4ohm.. it did about 2x40watts RMS on a bench.
