I am an MECP certified installer and this is the best sub I have ever owned. I have one of these (dual 2 ohm)subs wired at 4 ohms hooked up to a 1200 watt sony explod amp in a sealed box. Box volume is critical for these subs to work and make sure you don't have an underpowered amp. If you like accurate punchy bass like I do, then use a small sealed box and this sub will fkn amaze you.
I got 2 of these in a custom fiberglass box with a MTX Thunder 81001, and sounds great. It could be better if the box was built to specs, but got them for $300/ pair brand new so it's worth it.
Its sad to see a MECP certified installer using a Sony Explod amp , They dont push anywhere near the wattage it says it does , electrical laws .. check the fuse ratings ..
i have 2 of these on a fosgate frt5002 amp and they want more power slam the crap out of my tibron best set of subs i have had
