perfect and value priced

I have this amp running 4 lanzar 3 way speakers in a 08 f-150 this thing makes them scream(in a good way of course). It is running off a kenwood kdc 642u. This amp has all the adjustments you need to get crisp clean sound a great buy in my book

great amp

this amp really make my tweeter sound so clear and loud too

Great amp.

Great amp, gives my 6.5 Pioneer speakers plenty of power and never had a problem with it.

Great amp

Great amp I was using A 400w and upgraded to this amp. And wow it sounds great clear and loud and even in full mode you can give the rear or front or both A little bass boost great for adding A little extra bass to back 6x9s and keeping your fronts in tune. The added settings on this amp are A big plus.

Great Amp!

This amp is highly recommended. The specs are excellent and you can push this amp for all it's worth. It is a very clean amp. You get a lot of amp for a small price.

Great Amp For the Price

This amp provides lots of power, but there are a few cons to the cheap price, the crossover knobs are a bit cheap, mine were bent, and its does heat up a lot affecting sound quality. other than that this amp is great. add a few cpu fans and you solve the heating problem

loud n clear

this thing is powering 2 powerbass 6x9s n 2 6.5 components,4 a cheap amp it sounds great. its perfectly priced here since i payed more.

great

I have this pushing 6 infinity speakers it gets so loud in the truck it hurts your ears also no distortion. Great product.

Good amp for the money

This amp will push the mids and highs fine, t.h.d. is fair. Dont overdrive your gain it will heat up. As long as you follow the rms and load impeadance it will do as advertised just as many other amps will. It took the place of my JL 300/4 series amp. Dont undergauge the wiring. Short as possible ground and jumper ground back to deck. This will keep motor noise to a minimum. I miunted a microfan on the ventilation to extract excessive heat as my set up is a TMA 1000 mono amp pushing two infinity perfect 10's JL 500/1 driving to soundstream 8 mid woofer/subs and this SPL FX4-840 is driving my rockford 2x 6 1/2 2 ways and my 2x M&M Polk audio 6501 series seperates. It performs well with all this crammed into a 88 chevy c1500 sportside single cab! I get 132 decibels.
