November 27, 2008hey guys been a little while, but im getting ready to finish the system in my crew cab. I was going to add 2 10 inch JL 1 subs in a box behind the back seat with an alpine MRP 500 watt amp to match the amp looks wise to the door speaker. My problem is the shop says they have had the amp on back order for 3 weeks now and i dont want to wait anymore. so they said they could put in an MTX, Pheniox gold ( i think thats the name) *or* another brand. The cost is going to 500 for the 2 speakers box and amp including install. Does anyone know anythink about the other amps mentioned *or* should i wait for the alpine?
