Replaced my 12 year-old Sony 100x2 amp that drives 2 Infinity 6x9's (also 12 years old) with this awsome amp. Needless to say I am buying new speakers now. This thing rocks! It's a great package although it was hard to find a discreet install location in an older Explorer since it was larger than I estimated. Check the dimensions first! It went under the back seat but I have to slide it forward to lower the seat. Oh well. Infinity products are superb.
