Seem to know their stuff. Can be a bit pricy but price-matched when I mentioned what another local retailer was selling the same HU for. Never tried to up-sell me on something I didn't want (with the exception of some deadening I plan to do myself). They were patient with my noob-ish understanding of car audio.

About a year after the install of my HU, I was having some issues that sounded like a blown speaker. Turns out it was a defective HU. Peter didn't have any in stock so he actually pulled the HU out of his car (same model) and replaced mine on the spot. Haven't had an issue since. Plan to go back to get my comps and sub put in soon.
