Do it!

If you have a truck and want to maintain your seating and ALSO have some good music….get these subs in dual 4 ohm and get the Alpine 1500 mono, have a reputable shop build your box and enjoy. These things beat for shallow subs under my back seat. I was anxious about the money I spent, but as soon as I heard the results, all concern went away.
