Small 4-Channel Amp

Hello,

Do you think I should fix my MTX 404, buy a used RF 400a4, buy a new MB Quart DSC450 or buy a new Hifonics Txi4408?

I have an MTX Thunder404 with bad solder on the RCA inputs. I got the MTX because it's little and easy to fit in small places. This amp doesn't have as much power as I would like. I also have a Rockford Fosgate 400a4 in another one of my cars which is even smaller than the MTX and has better power output. I looked at a bunch of new amps, and not many manufactures make amps as compact as they used to. I've listed some of the new amps that are below.

MTX Thunder404

35x4@4-ohm (pre CEA-2006)

2.25x9.81x11.56

need to fix, not sure what cost will be or if I can fix it myself yet

Rockford Fosgate 400a4

50x4@4-ohm (pre CEA-2006)

2.60x9.60x9.70

used, not sure of cost

MB Quart DSC450

50x4@4-ohm (not CEA-2006 compliant)

2.70x9.45x11.02

$87 new

Hifonics Txi4408

55x4@4-ohm (not CEA-2006 compliant)

2.36x9.07x12.60

$115 new

thanks!

look on ebay for a bnib cerwin vega exl 400.4. its got 65x4@4 iirc. and its an arc cxl (or something like that) clone. same zeff designed board. basically the same components. solid amps. best bang for the buck bnib money can buy.

I appreciate the suggestion. I looked up the dimensions on sonicelectronix (2.20x9.20x15.00). It's a little longer than I'm looking for.
