Find another place if you want customer service Placed a order on Sept 20th UPS label marked shipped.I haven't received and UPS says they haven't received the items. When emailing either no response or the ones they answer is no answer. Customer service is the worst I've dealt with in a company and I've ordered alot of stuff from other places with no issues. The person that helped me seemed more suited with a coloring book and crayons than customer service. First and last time ordering from them.

Customer service non existent watch out Customer service non existent I guess they make enough doe they don't give a chit! Canceledan order and switch amps was told expect refund 2 to 3 biz days. Fair enough. It now been 10 they don't answer the phone when they do they say we tried to refund your card wont except it. Excuse me that's complete bull. So contested the charge with my credit card. Sure hope their equipment is better than their service. I'm having my doughts now

Hands down best service Hands down best service, fast shipping, good people. Best priced car audio equipment especially the JP amps. Can’t beat those amps for the price and they’re underrated so they put out more then they say rms wise.

Trash Customer Service Purchased a couple of 12s from them, both were damaged. Made me pay shipping to get them fixed, and also made me pay the restocking fee even though I reached out the same day I received them. Customer service sucks, and if you receive a damaged item, it’s not their problem, and don’t expect to get your money back.

Worst customer service. First, in 2020 I bought two amps.with extra warranties for 2 years, on 2021 they get smoked, so I asked Wolfram to send me the RMA # to send them for fix. (to: The Amp Lab, in Fairfield, Maine.) I paid the shipping, and finally they fixed. Last year I bought another one, but Last February 2022 one of those they have fixed it smoked again. 45 days ago I have been tried to contact Wolfram by e-mail, on Facebook, by phone, but the 2 phone numbers I have are disconnected, gues maybe they went out of business, if so I'm pretty sure Down4Sound and JP know Wolfram is out of business, wouldn't be better if they tell us the truth, what is going on, be honest with the customers, unexpected things happen but not "beat around the bush" Also I messaged JP on Instagram, (he never answer me back) sent a message to: Down4Sound page too, called Down4sound like 3 times, to get support from them and they just told me: they are so busy, "you need to be patient" I contacted: Colin Buckeye (used to be like a Wolfram Key principal, but he's no more working there) through a message and he gave me the name of Tim and his phone # so until the 2nd time I called him he call me back and gave me the RMA link, and still waiting for Wolfram response, I'm pretty sure I won't ever gonna receive it. Don't waste your money and your time in here, look for a well established company, like: Sonic Electronix, Online Car Stereo, Crutchfield, etc.
