This battery works perfectly for my needs. I have it powering about 4K watts and it handles it like a champ! Minimal to no lights dimming when the bass hits!
I was able use this battery to play my car audio sound system for a backyard party for 5 hours without running the vehicle engine. The system consisted of a Hifonics BXX4000 playing 2 Sundown SA 15's, 2 Hifonics Zeus Elite 2000.4 playing 8 Audiopipe 8's and 1 Hifonics BXX 800.4 playing 8 Audiopipe Tweeters. The system never clipped once for a power or voltage drop. This is an amazing battery that I recommend as I am totally impressed by its performance.
Needed these 2.
I had originally purchased the battery for my 1988 Silverado but I sold it before I could install it into that. Ended up using it in the trunk of my Honda Accord to help add reserve batt power for the sound system. It's been in the trunk of my car for the last 5 years without any issues and I would buy it again. I did have it connected from the stock battery but I would highly recommend that it only be used in conjunction with another AGM battery even though I didn't have any issues whatsoever. 10 out of 10 recommend the battery, just buy it.
1st battery lasted 5.5 years. Here’s to another 5.5! Only battery I’ll run with my system.
