Came to big Jeff’s after getting screwed around by another company. A month later, after much frustration and wasted money, I ordered the lfp battery. It was processed and at my door in 4 days. That’s why I will keep coming back. The lfp is the perfect size to fit behind my seat.
Big Jeff and B2 is killing it awesome brand even there appeal is quality
I ordered 2 of these subs and let me tell you. They got some weight to them. 67LBS for a 10?? Sheesh!! I haven’t installed them yet, still waiting on amp and enclosure. They will be on DD M8k, I know they will be putting in that work!! Only complaint is I didn’t receive my Big Jeff’s camo hat but no biggie. Just super happy everything arrived undamaged and super quick, thanks to Big Jeff and the team!!💪🏻💪🏻💪🏻
I am in love with my E-12 on just a Sundown sub-600d it hits so damn hard ! But I want a little more bass in my life , so I got the 15” version, Hands down the e series is the best sounding sub for music I have ever heard and I am 44 years old lol , wow sundown is all I got to say lol I am definitely a believer in sundown subs and amps
Product sounds good but one is making a rattling noise from around the cone area.
