Continuous output
Up to 400A continuous. It holds while the subs hit.
Other batteries: Limited output once the load stays on
Tesla, gas, RV, and small solar
Add bass. No codes.
These packs also excel in a gas car, an RV, or a small solar setup. We just focus on EV subwoofers. That is the hobby.

That part is up to you. The biggest hurdle is not knowing where to start. We get you the battery and the charging. That is the important part. Then you pick the rest of the system, and who you want to install it. People also think real audio will mess up an electric car, the high voltage, the electronics, all of it. And most shops will not work on an EV because they have never done one. Those are handled. We built this with a pro shop that normally does gas cars, with Tesla, and with the battery manufacturer. A little more output and no extra space, or competition loud. Same safe, high-output LiFePO4 packs either way.
Replace the stock sub, or run it in the sub trunk. You are not taking any more space than the car already uses, and it is still way more bass than factory. Every person who has sat in it, whether they build this for a living or they have no idea what they are hearing, cannot believe it.
People stall because they have heard every reason to wait. High-powered electronics, range loss, codes, extra load on the car. Those are misconceptions. Our own vehicles have been on 200Ah packs and 8,000 to 9,000 watt amps for over a year with no issue. Gas or electric, the easy part is putting one of these batteries in.
The packs are underrated. The BMS number is the safe continuous rating, and normal music never holds the 10 seconds it would take to trip it. The extreme is @evaudioexperts on TikTok. We can do anything smaller and cheaper than that. The battery and the parts ship anywhere in the country, and a local shop can install it.
Why these packs
The pack is the system. Same idea as a Tesla: RWD, AWD, or Plaid is the result you pick, and the battery is what gets you there. 50Ah in the stock sub spot or the sub trunk is more bass than factory and takes no extra space. Move up for more output. 200Ah is the Plaid version, a wall of clean bass you can hear more than six blocks away. Every size is safe, high-output LiFePO4. No codes, no alternator to deal with, easier on a Tesla than even a gas car, which is the main misconception, and priced so you can start.
Stable under load
Voltage stays up. Subs hit clean. No dimming, no distortion.
Other batteries: Voltage drops under a heavy hit. Lights dim. Sound breaks up
Safety
Stable LiFePO4. A puncture or crush does not send it into thermal runaway the way other lithium does. BMS and Bluetooth on the pack.
Other batteries: Basic protection and a higher chance of heat and fire
No codes
Add the bass. The car stays quiet. No warning lights. No error alerts.
Other batteries: The car throws a code when the voltage falls
No alternator
No alternator, no problem. Easier to install and easier on the vehicle. Gas or electric, same setup.
Other batteries: The system leans on the alternator and the install gets harder
Capacity
50Ah up to 200Ah.
Other batteries: Usually stuck around 50 to 100Ah
Life
3,000 to 5,000+ cycles.
Other batteries: About 500 to 1,000 cycles
Weight
Lighter and easier to place than the bulky packs.
Other batteries: Heavier and bulkier
Price
High output and stable voltage, for less than other packs doing this job.
Other batteries: More money, and the voltage still falls off
Four sizes. Same chemistry.
100Ah and up include a wall charger. Want the pack to top off while you drive? Ask for the converter on the form. This first batch is priced cheap on purpose. Want a different kind of battery? Tell us on the contact form.

A basic install guide with the battery.
We supply the battery and the charging. You pick the amp, the sub, and who hooks it up. The PDF install guide is $40 added to a battery order. On its own it is $99. High voltage is a fair concern if you do not know what you are doing. Take it to a shop, or finish it yourself if you are inclined. You get a PayPal request to pay.
