3 choices in 4x50 amps please help

[Hookedup12 10+ year member]

I got some pioneer speakers that rms at 45w what would be the best 4 channel amp between these

Three

Mb quart ONX4.60 @ $99

Alpine mrp-f300 @ $149

Kicker dx200.4 @ $149

Or would it be best to just power my front stage with a Boston acoustics 2 channel

But with only powering my front stage would my balance be off in the car???

Get MB Quart REF4.50 from sonic for $89 while they last (LINK), or get the REF4.80 if you can find it. Why? I have seen a test review of a bunch of 4-channel amplifiers, including REF4.80, and it came on top. REF4.80 is rated for 4x80watts at 4ohm but benched for 4x110watts (and 4x180 at 2ohm). It's also very clean amp with low distortion, good channel separation, etc, very small, but it can get pretty hot in summer. I assume that by translation the REF4.50 should also be pretty good. The ONX4 series though should be a fine budget amp, but probably not as good as the discontinued REF4 series. The Alpine is also a nice clean amplifier, not the most powerful, but very well implemented, and since it's class D, it will run cooler when driven hard. This is an important consideration if you live in the sun belt. Alpine amps are often underrated by some 20% or so. I have seen a test of F300 showing is does about 4x65watts RMS at 4ohm/ 4x100 at 2ohm.

Boston Acoustics GT series are very good amplifiers though. There should not be a balance issue. Most sound should come from the front, not rear of the car. I'd still consider getting a GT-475, so that the front could eventually be converted to active front stage with the extra set of channels.

@Hookedup12 ; if you were offers a Focal amp for the price, or less, of those choices you posted... you are making a mistake by passing it up.

Are the focal solid 4's good amps though?

Yes. The chief complaint is how they're too expensive, not that they're low quality. As much as it pains me to direct you away from the amp I offered, everyone's right. If that focal checks out, it's a steal.

You have the ability to be honest lol most ppl would have still recommended me theirs. Thank you. I guess I'm iffy because I've never heard one nor have I ever heard anything from that company.

that is a freaking steal on a focal for sure...

If you don't get the focal, look on Sonicelectronix.com Vibe Audio 4 channels... very nice amps

Dont worry about getting an amp that puts out more power than the speakers are rated for. You just set the gains correctly, and you will be perfectly fine. SQ guys will buy amps that are too powerful and dial them down because that means there is even less distortion. Focal makes some of the best SQ stuff, but like it has already been said.... the main complaint is price (kind of like JL).
