Hy, I want to upgrade my midbass amplifier (focal 165k2p) and I don`t know wich one is better for my set up (alpine 9835, focal k2p mid, hybrid L1 Pro tw).

The Hybrids are moved by a small Zapco Z50S2.

So:

1.JL 300/4V2 ~200+$

2.Zapco Z150S2 My link My link2 ~150$

3.Zapco 350 Driving Force: Stereo, 4 ohms: 2x100 Watts

Stereo, 2 ohms: 2x175 Watts

Bridged, 4 ohms: 1x350 Watts

T.H.D. + Noise: <0.015%

S/N Ratio: >95dB

Slew Rate: >29V/uS

Optically isolated MOSFET power supply

Surface mount technology w/1% resistors,

precision caps, and massive ground planes ~ 320$

Of those three options, I would go with the JL and bridge the amplifier for 150w x 2. It appears that would give you the most power output.

That said, I personally would probably go with another option like the Clarion XH5410 for $220 shipped which would give you an available 320w x 2 for the mids

EDIT: Damn, didn't realize you were located overseas Guess that Clarion deal might not work out for you then. But the main point was, I find the most quality power I can for my dollar.

I allready have 2x150W....I wan`t more quality, more SQ from an amplifier for my mids, not pure power:P.

I was told that the JL is very good for a "&quot;SQL&quot;" aplication(i know it`s a forbiden word:P), something like loud and clear, not true SQ....what can you tell.

Yap, i`m from europe, good damn the shipping`s costs.

Well, then you are completely wasting your time. If you are having problem with the "SQ" of your mids, you need to look at your installation, your tuning or the capabilities of the mids themselves. Your amplifier has nothing to do with the "SQ" of your speakers unless you are clipping your amplifier or the amplifier is broken. Using higher powered amplifiers increases your available headroom (<- click the link if you are unsure what I'm referring to) which is the biggest benefit you can gain sound wise from changing amplifiers aside from replacing one that's broken.

Not sure who told you that, but that would be about as incorrect as possible. As a matter of fact, the individual who designed the JL Slash amplifiers, Bruce MacMillan, also designed the highly coveted PPI Art line of amplifiers as well as many other well loved "old school" amplifiers from companies such as Xtant. That said, there's no such thing as an "SQ" or "SQL" amplifier. But the man who designed them certainly knows how to design a great amplifier.
