2003 trailblazer radio

Has anyone heard of these companies? For accessories which would be the best quality? I know accessories can't be that big of deal. But from personal experiences what can you suggest? I've never heard of raptor.   

I know warlock alarms, fishman audio, and balistic audio are new and up coming audio companies.

It never hurts to go with new companies and long as they can take care of there people. Have good products, same options on their products as competitors and low prices. Shipping,etc..

I love going with stuff that no one has never heard. Even though on a business aspect people may be leery of going with that product. Espically if they have not heard of that company. Back when I bought my RE subs. Friends would say RE? I'd be like yup, I've heard that rock. Once I put there product in my vehicle my friends are amazed.

I'm opening a lil shop and just want to make some good choices (don't we all) on which products I should go with.  How many stores do you walk into and you see stinger, tsunami, raptor, audiobahn accessories. Like they four different brands of fuse holders, wire, dist blocks, etc.. You get what I'm saying? Well I'm blabing on so I'll end on this note. LOTS of choices!
