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.

First I want to Thank Noel for Helping… First I want to Thank Noel for Helping Every Day For 3 Days with the financing. They were down to only a few People and She still found the time to Help EVERY TIME!!! Second COME ON MAN They have the best Subwoofers Online. If You’ve done research with the other big Companies You’ll See His selection is 10Xs better.

JP has created an online retail… JP has created an online retail experience for the car audio industry second to none. The claims are true. Best pricing, best selection from high end to moderate entry level equipment. Shipping is super fast. Period.

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.

Please rethink your purchase from here. His return or may I say replace policy is terrible. Only plan of replacing a faulty amp 1 time any other time he will talk down to you as if you're a child and you're stuck with a paper weight. The first amp was faulty and the second lasted 4 days. All electrical was up to par and it wasn't user error so no one can blame it on that. He just let go two of his best employees. One was his enclosure builder. Now no one else is building enclosures for him and if so no where near as great as the original. The second was in charge of packaging, shipping and delivery. I normally don't do reviews but the people must know. He got greedy what happens when you get greedy you lose it all. OH and who charges 25$ for his signature that when he's not there to sign it someone else does...
