Sub amp recommendations for 3x Boston G510-44 (.67 or 2.67 ohm)

[ealvar]

Short version:

Looking for suggestions on an amp that will do 1500w RMS into either a 0.67 ohm load or 2.66 ohm load. This is a daily driver and will never see a meter. Looking for SQ. Subs are three Boston G510-44 in 0.3ft^3 sealed.

TLDR;

Just when I thought I was out, I pulled myself back in.

After a long hiatus from car audio I went and bought a new Camaro that is clamoring for bass.

It's been a few years since I did my last build (a modest single 10" Boston G5, 450x1 from Boston GT-22, Boston GT40 to Image Dynamics CXS64 active, Eclipse CD7000 HU), so I'm looking for input, opinions, recommendations.

I'll be running at Boston's recommended 0.5ft^3, sealed, in a 3 chamber enclosure, rear firing. The G5 are rated at 450w RMS. I'm not looking for SPL, but SQ.

Given the odd number of subs I'm looking at either a 0.67 ohm load or a 2.67 ohm load.

My dilemma... I have pared down my amp collection and sold off the big hitters (Directed 1100d ('99 version), Boston GT-24, Directed 1200t, etc.) and I'm left with more modest multichannel amps.

I have an Eclipse XA5000 (50x4 for components, and 450x1 @ 2 ohm for a sub). Boston GT22 (450x1 @ 2 ohm), Boston GT40 (55x4 @ 4ohm or 245x2 @ 2 ohm).

So I have options, but it would mean giving the subs unequal power; e.g. 450x1 to the center G5, and 245x2 to the left & right G5s. I don't want to run more than 2 amps.

I'd like to get at least 275-325 watts per sub, which should be plenty of power for every day music, but the OCD in me wants at least RMS, or more to have some headroom.

Should I just pick up a new/used sub amp that will have enough juice to push these guys? If I go that route, i'd like to just get something that will push all three subs @450w or more.

Any recommendations?

I love the Boston amps and can pick up a GT2300 which should put out around 450w per sub at 2.67 ohm.

Are there other amps I should look at? Anything out there that is sub ohm stable if i go the 0.67 ohm route?

Budget is about $400. Less expensive is better

Thanks,
