Thank you
This battery is very strong and don’t take up a lot of space
That Limitless starts my bike up like a brand new bike.
On time nice doing business
I recently purchased a Limitless Auto Lithium battery for my Harley from TDS Car Audio, and the entire experience was outstanding. The price was very fair compared to other places I checked, and the battery arrived much faster than I expected.
The ordering process was smooth, shipping was incredibly quick, and everything was packaged securely. It's refreshing to deal with a company that offers great pricing without sacrificing customer service. If you're looking for a Limitless battery or other quality car audio and power products, I highly recommend TDS Car Audio. I'll definitely be a returning customer!
Fast Shipping
Great shop and Bryan Great to work with
It was a perfect order. I placed my order after hours. Sometime the next morning (Friday before Memorial Day) I received notification that it was shipped and received the tracking number. It was shipped and I received Tuesday, the day after Memorial Day. It was as easy as placing an Amazon order.
I haven’t received the sub yet, I’m still waiting on it and have had no update. I would like to know the status of my order.

Product as described. Super fast shipping. Got it two days.
You guys were awesome. I found the speakers I was looking for. It looks like y’all have a good selection of car audio equipment. I’ll definitely be coming back when I need more things.
They get u wat u need, shipped and out the door had my order with in a couple days
