great value!

This thing looks amazing.. at night the blue lights look sharp and it has plenty of power for any type of system you have. I love it. The only thing I didn't realize, is how big it is, it is bigger than your normal cap. It wasn't a huge deal for me, but when u open my trunk this cap takes the show.

Good but not great

Does not fix every electrical problem. I still had major dimming even after installation because of the voltage drops. Though it did not make the voltage where it needs to be, it made the bass powerful and clearer until it is drained. + It matches perfectly with my SPL amp.

Great Deal!!!

I purchased this 6 months ago and this SPL 6X Farad Works Great, Always Has Full Charge, and Dosen't fall much at all on voltage while under strain! Thanks a lot, Joe & God Bless!!!

not worth the money

I bought this unit to replace a smaller cap that was all ready installed. The volt meter went out in 2 days. The cap came with short bolts only so my nice wire ends would not fit. After 2 weeks the case split at the seam, so I took it out.
