I have two old Jama subs that died within a year of each other. Would be a shame to just throw them away. This product fit the hole perfectly, and works just as well as the old Jamas did. Took me about ten minutes to install and set up. I am a huge fan of Dayton Audio products.

I’m quite happy with this amp. I had a passive sub woofer that I cut a hole into and installed this amp into. It really booms and adds a lot of dimension to my home theater set up.If you are looking for an easy way to upgrade a passive sub box this is an excellent choice.

Parts express helped me via email with wat I needed. Actually saved me about 35$ from wat I was going to buy from them. It preforms exactly how the tech guy said it would. They wer very helpful & cool about giving advice. I will purchase all the stereo stuff I need thru them from now on. Also they told me the 5yr warranty is still very valid although I purchased it from Amazon. Had to, I don't have the pay pal watever

I got this amp to replace my other one cuz something is wrong with it. I expected it would do around the same as the other one. This amp is way stronger than my old one. My sub sounds so good during movies, and really good for music too. If ur sub needs like 400w rms, maybe get a stronger one but for the sub that needs 200w and under this is ur homie.
