All the 1 stars on durability leads me to believe the majority of people dont install this amp correctly. If you are going to have an amp this size you need to do the BIG 3. If you dont "YOU WILL" burn this amp up. This isnt an entry level 4 AWG wire from battery and done amp. You need the BIG 3. You need an extra battery. If not any amp this size burns up.

Single 12" MD Sound 12-12175 into 1.5cuft sealed custom fiberglass box. Dual 2ohm. Running parallel for 1ohm load to amp. 3farad capacitor.

Seat-of-pants-meter is telling me an honest 1000-1500wrms or so, maybe more. Can bottom out the subwoofer at higher power. Haven't clamped the output so just guessing. Great bang for your buck.
