AWESOME! Posted by Joshua David on Jul 01, 2025 Awesome!!! Ordered and arrived in 5 days (free shipping), came with some dum dum suckers and a nice camo sticker Alright so, stock electrical, 2 10" Infinity kappa perfect 10.1s (old school true) 750rms combined. We know this amp can do roughly 850-900 on 2 ohms, and it absolutely does. Used vibration isolators on abs plastic sheet so space the amp a half inch from any surface, and it breathes great. 75 degree day, full tilt, an hour or two and it's sitting at 90 degrees! Again, about stock electrical. 120 amp stock alt, napa lead acid, and shca 4 gauge. Really, really good stuff for stock electrical. Didn't drop below 13.7 on full tilt. Hey I was skeptical before ordering, I was looking at the sundown SAEV4 1000.1d but for the JP8's power and price, I can't pass it up. Super, super satisfied. Worth it. TAKE CARE OF YOUR EQUIPMENT!
