hifonics, mb quart, cadence, crunch, autotek, powerbass?

Hey all, i got an around the way offer of a sponsorship by a guy opening a stereo shop near me. He's going to be dealing mostly with the above brands. What has you guy's experience been with these? The only one's i've heard much about at all is MB Quart, and i've heard nothing but good things about them. Basically, i'm probably going to be building a system from scratch, so i need any experiences you guys have with these brands. Thanks.

I KNOW A GUY WITH A FULL HIFONICS SETUP IN HIS TRUCK AND IT ROCKS OUT. REAL CLEAN SOUND. MY DAD HAS N AUTOTEK AMP WITH A JL MICROSUB AND ITS ALSO REAL NICE

I had a buddy with hifonics amps running Orion 15's, powerful amps..i have a set of MB Quart 6.5's and theyre amazing, i have all jbl gt speakers in my car and my mb quarts sound better imo

Hifonics, Cadence, Cruch, autotek, and powerbass are all intry level to mid level nothing great but not crap. If its free i say go for it you cant lose.

I've always had good luck with Cadence, havent used any of the newer stuff, but back between '98-'01 they made some awesome stuff.

MB Quart, Hifonics, Crunch, & Autotek are all owned by Maxxsonics. I've got a Crunch amp pushing 4 L7 10's in my wifes car and it does a great job. I don't like them for mids & highs though. Just never sound good to me. I've used Hifonics a few times also and they are a good amp. As far as speakers go, I've never sed any of them.
