i bought a 1700w dual voice coil power bass sub woofer and a 1500w 2 channel autotek amp from them and i installed it in my car and that was a very good combination they chose for me and it was good it lasted a long time till someone stole it but for future system i will go back to them they have good service and great items for sale. they are what some call overpriced but u get what you pay for so it is worth it. they also install them i can't wait for my next one hopefully soon. try them
