Training at Big Jeff is different than most of the other places I’ve worked at. For instance, it’s hands on and using lots of resources to get the right information, instead of a bunch of training videos, scenarios, or new...

Maybe it’s over priced maybe he shouldn’t put his face on it but it still gets 5 stars from me
Quality built speaker with an amazing sound.
Everybody's always want to be sure when it's their first time. And after seeing the quick response time and just the great professional service.
its my go to for car audio equipment
Lost for words... this thing POUNDS and Sounds great!!! my all time new favorite amp, definitely upgrading the wife's SUV with some DD audio. Do your self a favor and buy one.
Thanks Jeff! Shipping was great. Sticker quality is great… proud to rep!!
I recently purchased a 9v speaker polarity tester from Big Jeff and through out all my years of installing systems I never had one. The shipping was fast and I'm glad I now have one in my possession to make testing fast and easy....
This works great. I can easily check to see if i gain from different mods i try. Reads slightly higher than termslab. I bought it through Amazon sold by Big Jeff.
Great Batteries, small enough to mount under the rear seat.
Had the battery in almost 2 weeks now.... My car is like a theater playing all music!! 300amp battery Isolator, 250 fuses, 3k taramp on 1 XFL 12- 1ohm... Extended port 4th order box 4cube Flexin Deep!!!
Just by looking at the wire and holding it you could tell its the real deal. Solid quality and very flexible. Im sure when I finaly instal it, my amps will run way more efficiently. The only thing I recommend is to figure out a better shipping rate and method. 5 ft of 4 awg and 5 ft of 01 awg were both 10$ even making it 20 all together. I dont believe that was accurate, at least for the 4 awg wire. Seemed a bit high. Not to mention I live in Florida... Im sorry but there is no way that 3.4lbs of wire would cost 20$ to ship in the same state. It was literally about the same price as the wire
I love this amp I’m gonna keep it forever .
I bought one credit and just installed today and this box bump like no other and im push the kicker comp q blue label 2 ohms 1k watts rms a piece running two and this thing is beef and a little to wide for my back seat but im make adjustments too and will recommended this box to anyone want loud bass on low volume on deck
It fits perfectly in my 2016 Kia optima with 2 sundown xv3 15s and sound amazing. Double baffle subwoofer mount. Only criticism i have is the glue use is some kinda silicon. I would rather see some titebond.im gonna apply some myself and let cure and I'll have no doubt this box would last without tearing a panel apart
The box was well built and sounds amazing tuned at 40 hz. Everybody tells me they can hear them from down the road. I have 2 American Bass 10” Hawks they sound amazing in this box. Couldn’t be more happy with purchase.
I bought 2 for 2 different vehicles, they worked great. I then consolidated the 2 into 1 system, they work phenomenally together. Instant burst power, awesome. Do your own research on the product before blaming the dealer or manufacturer. Thanks Big Jeff, I purchased mine through you on Amazon.
