Customer Reviews
solid shop, just a bit tricky
grabbed OFC Power Cable, pretty good but that checkout code entry was almost missed, 4 stars.
Good prices and fast shipping
Needed some Wire Ferrules and they had them for a decent price. I always compare with Sky High Car Audio and Amazon, and Down 4 Sound usually has competitive pricing, especially with their auto discounts on certain brands. My order shipped out quick, and tracking was easy to find in my account section.
solid shop, almost perfect
better than amazon for car audio stuff, that's for sure! this is like my fifth time ordering from down 4 sound shop and they're always super reliable. grabbed some d4s apparel this time and a new sundown audio subwoofer, was wondering if they were an authorized dealer but everything looks legit. the deals are pretty good, got an automatic discount on the sub, saved a nice bit of cash without even needing a code. only tiny thing is i wish the apparel section had more variety sometimes 🤔 but overall, still my go-to over sonic electronix or crutchfield.
Good amplifier, slower shipping
I ordered a JP234 Amplifier last month. The amp itself is solid, really brought my door speakers to life. Installation was straightforward. Shipping took about 8 days to get to my place in Florida, which was a bit longer than I expected, especially since I've had faster delivery from other car audio sites. Customer service was responsive when I inquired about the tracking, so that was a plus. Overall, a good product and decent experience, but they could speed up the shipping process a little.
Great value on subwoofers
This was my first time buying from Down 4 Sound Shop. I was looking for a new subwoofer and found a D4S Subwoofer in their clearance section. The price was really good compared to what I saw elsewhere, definitely felt like I got a deal. Shipping was fairly standard, arrived in about a week. The sub sounds great for the price I paid. I was a bit worried about buying online without hearing it first, but it exceeded my expectations for the cost. Very happy with the value.
Consistent quality, always my go-to
Another solid purchase from Down 4 Sound Shop. I've bought from them several times now, mostly for wiring and accessories. This time I picked up some OFC Power Cable and a new Bass Knob. As usual, the quality was top-notch, exactly what I expected. The shipping was quick, arrived in 4 days this time, which is consistent with my past orders. They always have what I need for my setup, and I trust their products. It's why I keep coming back.

Can you stack discount codes? Got a military discount but also signed up for the newsletter and got another code.
What's the deal with returns if I buy something and it's not quite right? Like, if the enclosure is too big for my trunk.
Do they offer any kind of financing options? Don't have all the cash up front for a big system upgrade right now.
Does Down 4 Sound do price matching? Found a better deal on some D4S wire on another site.
Is Down 4 Sound legit for real? Heard some horror stories about other sites shipping fake amps.
