People buying from them are clueless . There stuff is bottom line with 100 to 150% mark up. Here's a prefect example. there JL Audoi TR 690-TXI. is on there shelf for $289.00 They will tell you that they are going to give you a great deal and sell you a package deal and you can get them for $ 189.00. Wake up people. Look on the internet you can find those speakers for $ 60.00 To $ 70.00 everywhere. The number 4 wire that feeds your amps is Aluminum...Wrong. It should be copper. I just spent $ 1,300 for low quality stuff. What really pisses me off is they could've put good stuff in my truck and still made good money but they are trying to get every last dollar they can from you. People dont make the mistake i did. Recearch what you want, I just pulled all there cheep stuff out and replaced it with good stuff and it was still cheaper then them doing it.
