I got the ST900 with the 4 channel… I got the ST900 with the 4 channel Rockford Fosgate Amplifier. As of right now I have a pair of 4 inch 2-way KS series & a pair of 5.25 KS series Kicker Speakers. And it ROCKS !!!! I did a grueling 1.5 months of research before buying. Here are a few of the reasons I choose, Steel Horse Audio. #1. They answered all my questions in good time. And, the answers were verifiable. .. Even after the order when I decided to change form the 2 channel to the 4 channel amp, I had no problems doing so. With no up charge for the change. I made changes & can rightfully say I'm a pain in the rump as a customer. But, they were great about it all. Doing what had to be done to make sure I got the system, "I" wanted. Not what they thought I should have. #2. The system is high quality.. Including the wiring harness they include with the system. You're not going to do better than Rockford Fosgate amps for volume & sound quality. The Kicker KS series, 2-way speakers pump out a lot of sound. And, sound good doing it. The MTX bluetooth controller is top notch as well. To do better you'd have to spend a lot more money for a controller. #3. I've tested the sound quality & volume with and with out the shield. With out the shield I can hear it easily up to 80.. With the shield I can hear it at 90. No problem. And, it sounds good doing it. At 70+ with the shield I could listen to Traffic and enjoy the intricacies of the music. . Which is nice. #4. They offer a veterans 10% discount. And, allowed me to take a 1 minute video of me destroying my old useless boss system to satisfy the trade in offer. Saving me $17 in shipping.. #5. Warranty. The 5 year warranty covers "Everything" in their systems. A number of their competitors say they offer a lifetime warranty in big print. But, if you read the warranty info all the way through. You find that the major components are only covered for at most a year.. And, that after 60 - 90 days if you have a problem with the amp, speakers or controllers, you have to contact the manufacturer.. It's not their problem anymore.. If you have a problem with something in one of the Steel Horse systems in that 5 year time frame. They take care of it. They don't try to pass the buck. So, for me Steel Horse checked all the boxes.. Only problem is I got a pair of the 5.25 & a pair of the 4 inch speakers. When I should have chosen to get 4 of the 5.25 inchers. ha,h,ha.. But, it wouldn't surprise me if they worked with me to fix "my" mistake on that.. So, if you like actual customer service, quality components, a real warranty, and more. Go with Steel Horse Audio. I might just buy another pair of the 5.25 inch speakers. And use the 4 inchers on another bike I have with the Kenwood amplifier. . lol.

Be AWARE of these SCAMMERS if i could give 0 stars i would. TERRIBLE. customer service is awful, they do not respond to emails or calls. placed an order 2 months ago, it was supposed to take 2 -3 weeks to fulfill the order. NOTHING. i emailed them 3 weeks later and they responded 3 days later stating the order was on QA status, however, when I checked on their website it stated the order was pending, I checked again 3 days later and it stated shipping soon. it has been a month since then and still no shipment. I inquired about the shipment and they sent me a bogus lie stating that it was on its way,, yet no tracking number was given. Sent yet another email requesting a tracking number and they gave me more bogus answers. 1 week later, they send me an email saying " "We're happy to let you know that your order has been shipped!" and gave me a USPS tracking number...problem is, the USPS had not received the shipment, Steel Horse Audio had only created a label. emailed them again, and again everyother day for a week. now they gave me this bogus email..."I'm excited to share that your system was dispatched with our freight forwarder late last week. To expedite the delivery, we upgraded the shipping, and you can anticipate receiving it within the next few days. Tracking information should also be available starting on Monday, if not sooner. Thank you for your patience, and if you have any further questions or concerns, feel free to reach out." Guess what...USPS STILL hasn't received the package..beware of these scammers, they were quick to take $400.00 but very lackadaisy to respond to emails or just send the product that was purchased. Do yourself a favor and purchase anywhere else but here

RESOLVED My last review was less than positive, but it had nothing to do with the actual system! It was all just a huge misunderstanding and Jessica/ Office Manager was wonderful at helping me resolve it..... The system it's self was great, but it did not work for my bike. I like to wear the super patted helmets and I have super loud Samson fishtails. I will say I could hear the system very clearly bar hopping but not on the highway. The sound on the system was veryyyy clear as well. :)

Steel Horse Audio got my speaker pods Steel Horse Audio got my speaker pods, grills and all the mounting hardware to me in Record Time!!! I am extremely grateful for the great product and fast delivery service!!! Highly Recommend!!! Stephen
