yay! another coupon for next weekend. just used one yesterday and realized I didn't get enough stuff. gonna get some more next round and have everything put in all at once. the installation prices are average. same as if I go to some other place. I've installed stereo stuff myself in my car and it's not worth the time and hassle, especially since I don't have the tools, time, equipment, kits, parts, etc. I'd rather have a retail store do the job, do it well and take responsibility for it. I've blown fuses; I've had to change the locks on my car doors; and I've put head units and changers in my car. I'd rather pay someone else to do all that. besides, I don't want to end up saying "oops!" on my new $800 head unit. I don't think the warranty covers end-user installation goofs.
