The enclosure recommendations listed above are external dimensions which assume the use of 0.75 in (19 mm) thick material. If you are using 0.625 in (16 mm) thick material, subtract 0.25 in (6.5 mm) from each dimension. Do not use any material with a thickness of less than 0.625 in (16 mm) as this may compromise the rigidity of the enclosure. All enclosure volumes listed above are net internal volumes! Driver displacement, port displacement and brace displacement must be added to obtain the final gross internal volume. All enclosure dimensions above have already taken this into account. When using multiples in a common enclosure you will need to recalculate the enclosure and port dimensions. For assistance please contact your authorized JL Audio dealer or JL Audio Technical Support. We recommend the use of this in a bi-amplified system using high-quality satellites and a high-quality amplifier. We do not recommend the use of this with a passive crossover (coil), as this type of device will adversely affect performance. All specifications are subject to change without notice. |

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.
Limitless Lithium NanoHDv3 30AH and Battery Charger/Maintainer Combo - NanoHDv3/MTN
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
