..i will NEVER buy anything from custom sounds on lee trevino. They sell you a lifetime diagnostics on their installation, what they dont tell you is there is only a 1yr warranty on some merch..my alarm system has already broke down and i was told there was nothing they will do. Their equip is cheap,their install is 2nd rate and their cust serv is poor. Save yourself the time,cash and headache and shop elsewhere !
