Great Product

I bought this about a month ago and it has been working great. I was a little skeptical about it at first because it was so cheap. I have to say now that I dont regret buying it at all.

Excellent inexpensive crossover

A perfect, inexpensive crossover for a clean sounding system. Easy to install, lots of adjustability. Perfect for a mid sized system in a 2 sub speaker system.

Running this between a computer and 1000 watt DJ amp for my subs. Using a computer power supply to power it, works well!

Pyramid Crossover

Got this from a buddy for free, brand new. Hooked it up to my Hitron HA1000 amp going to my MB Quart 500 watt shallow and its amazing! Hits sooo much lower and louder than before.

Good Product

I have this cross-over hooked up in my car with two type E's. I would recomed this product because of the amp that i have is old and this cross-over helped boost the bass in my system. The thing i like the most is it's easy to use.

Great value

This is a must have for any body who loves car audio and big systems. The sound diff that this makes is unreal. Make sure you buy one or one like it. You won't be sorry.

Great with my Sub!

I've had this in my car for about a month now, and while I installed it with an amp and sub, I don't know much what it sounds like without it. I will say though that it was very simple to install and easy to setup with the rest of the system, and for the price, you have to get one. The only downside is the general look and config of it, but for under $12, totally worth it.

It's better than I expected

If you don't have these features on your amp, I would definitely buy this product.

there are no cons.
