You'll be shocked what this product does

Everyone in your circle is probably using many amps to give you the response this does. I have this with 4 12" EV's and have heads turning way before I get to where they are. I have always used Hifonics and always will.

Great x-over for the price.

If you are looking for a good cross-over at a reasonable price you found it! I resently installed this unit into a customers truck with other Hifonics components and it worked just as I needed it to. With the included bass knob it gave me all the cross-over frequencies I needed to adjust this custom system nicely. Great equipment for a system on a budget.

Best value for money

Never owned any crossover before and this hfxr gave me a great time, easy to install and easy to use, everything is laid out so well and user friendly.

In terms of performance, yes a good thumbs up cause it does its job separating frequencies and one more thing, bass knob has 40 clicks, level can be maxed out clean using DD-1,

Can do single input, dual inputs and full range inputs for this crossover, not sure is it mention in the description but yeah, now you all know.

Not sure yet

The setup for this product looks easy enough just haven't had a chance to install it yet, but have always used hifonics equipment and always pleased with the equipment I have purchased.

Dissapointed at first

First of all sonic electronix is the shizznit.. Fast shipment, on time and I always get updates on tracking unlike other online stores..anyways so I hooked the crossover when I received it I hooked it up to my sub amp since I didn't have my mids installed. I messed around with it and I couldn't hear any difference..(maybe I needed more time to tweaked the settings on my head unit and amp settings). After a weak or two I took it out.. Anyways long story short I ended up taking my sub amp and put my mids amp. Crossover has plenty of volume( I can lowered my amp gain) crossover settings are good. I'm not a big fan of Chrome but it actually does not look bad. One think I dion't like is the little plug that hooks up to power,remote and ground comes off easily and also the knob controls are a little flimsy.. Remote has a cheap feel to it.. But overall for the money it's a good buy.

Good product

Cross over works as advertised. Application is set up as a 3 way crossover. High pass set for tweeters,& dome midranges. Midrange set for 8" mid bass woofer. Low pass set for 15" subwoofer with sub sonic setting at 25 hertz.The first one I received needed to be returned due to bad light on the level control knob. Beware of the shiny chrome plating, the plating makes it difficult to read the settings due to reflections of bright blue LED.

Hifonics HFXR

Have not installed yet. But product came in a timely fashion. It was packed well with no damage. It fit the price range I was looking for in my budget system and the quality of the crossover feels good. I will leave updated review after installation with pictures.
