So I built my custom speaker my self .... but couldn't have done it without psi because I had no idea what type of coil would work with my American bass hd motor .... needless to say psi told me which coil to order and I did .... built my sub and wow its so loud .... running half ohm daily and it's well over 145 db ... on 2k with 1 12 inch woofer ....

There's no one to compare to these guys, my motor shifted at slam so I had David take it and build it into a monster and make me a marching drop in for my other zv4 motor so I can wall my little car.... #TeamPSI... See MoreSee Less

I bought my two PSi 12″ Platform 3s from a teammate after running about half a dozen other brands within a two or three year period and I was blown away. The way these subs get down is seriously impressive, playing down to 20hz in a 6th order hasn’t even been an issue for me. I take a lot of pride seeing the look on faces when they find out the wind they feel is only two 12s.... See MoreSee Less

Had platform 2 18s and loved them, upgraded to platform 4s and on the same power they played louder and lower. Can't wait to add power and really wake these beasts up! Psi ftw!... See MoreSee Less

Running 2 platform 3 18's. And never and issue. Fully loaded and take all 3k and more. Switched from another popular brand I noticed a big difference. Played lower and louder. Plus after finals witnessing David helping fix his subs that was a user error I seen first hand how good customer service was.... See MoreSee Less

When i ordered, my basket was out of stock but i was kept updated every step of the way. Would highly recommend to anyone looking for good products at good prices.... See MoreSee Less

I put 2 psi platform 2 15s in my suburban. I'm only running a rockford bd1500 for power and they are brutal. I just epoxied my rear ac controls back together, lock tighted many interior screws. Have not found a way to keep my rear view mirror from falling of yet. They sound good too. I'm not just about loud, I like a good clean sound as well.... See MoreSee Less

These guys deserve every bit of 5 Stars. The service is excellent and they get the job done. I had an issue with my first sub and after a few emails, I had it shipped back and while it took a while to get it back, once I did, they provided. They handled the problem with a professional tone, stuck to their word, now my system booms. If I had to describe the way their subs sound, it would be JL quality with SoundQubed or some other SPL brand SPL. My Platform 2 10" slams hard and has done nothing but impress me the few hours I've gotten to break it in. I have it running on an amp capable of a clean 1944 watts RMS and I cant wait to let it have every bit of that. So far, it's crunching the lows and eating the power for breakfast.

Long story short, you get more than what you pay for. Their subs may seem a little pricey at first, but the balance of quality and SPL more then makes up for it. I'm sold for life. Soon it'll be time for 2 Platform 3 10's in a center console build. ;)

h
well, seeing I'm only listening through home theater subs, I cant give a true rating, I'm getting a settlement soon, so, it looks as though these subs, and Sundown are the two to choose from, although sundown may not be in the running, it might come down to dollars, I probably wont have more than 3k, so we will see.

I can't even tell you how stoked I am to own one of your subwoofers! I got a 12" platform 1 with the performance upgrade about a month or 2 ago and it kicks ass. Definitely a lot more bump then I was expecting! Everywhere I go heads are turning, mostly to scold, but hey.. fuck it! Right! Haha. Makes me want more! I can't wait to upgrade... See MoreSee Less

Underrated on power specs for sure. Got a platform 1 on a 1200 watts rms orion amp and can run the sub for long periods of time before the coil gets hot.... See MoreSee Less

Best customer service in car audio. No matter how big they get they remain small enough to take care of even the small order customers. I had a problem with fed ex and couldn't get them to do anything about my package they lost. I contacted psi and they had the issue fixed with fed ex within an hour. After dealing with other companies that have become to big headed over the years to provide customer service like they should I'm pointing all my friends in psi direction from now on!...
