Pyle and Boss are same company from what I can tell.
Just depends on "who's selling them". If you know what I mean... So one doesn't compete w/ the other. Boss is found at Wal-mart, while Pyle is more often seen at Pro Audio Stores.
So... I own BOSS. And they are GOOD. I'm not looking down on it at all.
It's what I run in my SxS, right now...
BOSS AUDIO BR800 Marine Weather Proof 800-Watt Full Range, Class A/B 2-8 Ohm Stable 2 Channel Amplifier with Remote Subwoofer Level Control
And it is WAY more amp than I needed to run a pair of 400watt 6.5 speakers. But I bought it because of the waterproofing and the nearly all POSITIVE reviews.
I also run this BOSS
Amazon.com: BOSS Audio R1100M Riot 1100 Watt, 2/4 Ohm Stable Class A/B, Monoblock, Mosfet Car Amplifier with Remote Subwoofer Control: Car Electronics in my truck, pushing 10" sub.
Unbelievable AMP. See the reviews on it, as well.
Hope this help. I think BOSS is quality. I'd buy one (and have) without hesitation.
