Sound Storm SSL F4.400

Not bad for a budget amp, don't expect big things, 50 watts per channels x 4, really? Not really, more like 20-25 watts, which is not much more than some head units. Used it as bridge when my Hifonics Warror-Eagle bit the dust. Needed the small footprint.

When I had enough bucks upgraded to Kenwood XR-4S.

Installed with a pioneer deh-3000ib head unit and pioneer 6x8 4-way speakers. Sounded decent and got loud (nothing mind blowing for a guy that likes his music loud though), but removed for a day to try powering my speakers with the head unit. Sq shot way up (especially at louder volume) and spl remains the same if not louder than with the amp. Surprisingly still had excellent bass response from my 6x8s even after removing the amp. All in all felt like I wasted money on a 4 channel I didn't really need. Worked, just didn't do it as cleanly as my head units amp, and was overrated for rms power.

If it wasn't for this amp, my speakers wouldn't of been worth it. Made them so much louder!

For the price you can't go wrong. If your running loud subs and need the speakers to keep up with the bass then go with this amp if money's a problem. I have had this amp for six months and it still performs like it did the day I got it.

What do you expect from an amp that costs less than 50 bucks? Don't expect much of anything, and this amp will fill the bill.

The output from this amp comes from two old-school two-channel hybrid modules that produce no more than 16WRMS per channel. That's right. Sixteen. There is no switching power supply in this amp, the output modules run on straight battery 12V, so there's no way it can produce more power than that running an old school class AB power module.

How do I know all this? Because the amp failed after 3 months of use - blown output module - and I repaired it.
