I need Help picking the right amplifier

[Zach H]

Any recommendations for a 5 channel amp that has a 4 ohm f/r and 4 ohm sub channels. I’d like the sub channel to be 500 watts rms at least. I’m looking at the JL HD900/5, but the price is astronomical!

I'm running one of these pushing components up front and coaxials in the rear with channels 5 & 6 bridged to my front sub. I've got zero complaints about it and I've ran it hard for a good bit now.

Bridging channels 5 & 6 will give 700w @ 4 ohm to your sub

I have two kicker compR12’s dvc 4 ohm, they’re rated at 1000 peak 500 rms wouldn’t 700 rms fry them?

Nope, unless you set the gain too high for input signal. They won't see 700w consistently unless you're playing test tones. Music is dynamic and you'd be surprised how little power a sub sees most of the time. 700w would give a little dynamic headroom

Ohhh okay, that makes sense. So that amp you suggested would run two components at 4 ohms and two coaxials at 4 ohms and my two kicker 12s at 4 ohms with no sweat? Any suggestions on a quality speaker set?

You can also set up your subs at 1-OHM. There are quite a few 5-channel amps that will do that, such as the Sundown Audio SAE-1100.5.

I know I could wire impedance down, that would open my options up. But I’ve been told the quality of the bass sounds better when the subs are wired at a higher impedance.

Just remembered, I have that same coaxial/comp set, BNIB, $245 shipped if you are interested. I have the matching coaxials, took these of the components. This was going to go into my brothers restomod build, engine is so loud, had to go with pro-style drivers (unfortunately).

You heard correct. Plus, 4 ohms gets higher efficiency and less of a strain on the amp and electrical system.

How did that music sound with 1 ohm sub? Loud, not too loud, good, totally junk. Even though it may have worked. Did you like the outcome? The sound.
