Very powerful amp that demands an ample amount of wattage, an extra battery is recommended as voltage drops heat the amp up and it doesn't get to push to it's potential. Though very powerful the ratings aren't completely accurate. Expect ~ 2500 watts at 1 ohm.

This is by far the best amp i have ever owned and i have had quite a few. This bad boy fried the coil of my kicker l7 15inch sub the first day i installed it. i now have it playing 2 sony xplode 15 subs in a ported box and this thing hits soooo hard. My neighbours called the cops for me complaining everything in their house was shaking. I strongly recomend this amp if u are looking for the best and willing to forget the rest. Sonic you guys are the best. PS just bought a capacitor from this site cause this bad boy needs more juice.

SPL GRLA 5500/1D Amplifier , is of the highest quality that is compensated by the price! In fact, very good the price, very very good the product! I have mounted an SPL for to drive two subwoofers TC SOUNDS and managed to keep the current to 0.5 ohms. Is astonishing! I will buy other because I think it's a product that is worth having! is a "small explosive housing!".....

Not only did you provide an answer to my question quickly, but you went up and beyond your call of duty by informing me of other parts I will need in order to install my new head unit. Thank you so much for your help and expertise.
