Exellent value

Im from england and its expensive and hard to find a amp with a good power and clarity at a good price.
I ordered one of these from the states and boy is it great, it is crystal clear and got loads of power i have 2 rsd 6.5 components and a pair of rsd 690 6x9s and they thump beautifully and clean.
The only problem i have is this amp is massive and is difficult to find somewhere to mount it, other than that its great! Keep it up Phoenix Gold.

Awesome amp

purchased a rsd 500.4 and 1200.1 and love them, clear loud and work great with my boston component speakers and subs, i recommend the pg rsd line to anyone, so far trouble free and such. the black amps go with the charcoal interior in my suv. i will be buying future upgrades from sonix as well customer service is A+, they answered my questions to the fullest and quickly. shipping ands delivery was excellent, had amps within 7 days of ordering to my door. no complaints

love this amp too

the 4 channel their powering my sr 60 components front and back and over all sound quality is amazing everyone I've met and who has heard my stereo is asking what I'm running and how did i get it to be crystal clear with amazing bass that isn't over whelming but hits HARD!!! i love phoenix products been running them for 6 years testing and trying different products they've produced and at the moment I'm really happ. I also i don't know what their new product line is like but i know these are the last of their good reliable products. i bought this from Sonic and love it, i was running the phoenix gold octane r 8.0.1 for 5 years and needed to upgrade to something new so i purchased rsd 1200.1 and also the rsd 500.4 and these amps rock, i'm running the 1200.1 at 1 ohm for the last number of months trouble free pushing 2 Boston g2 10s and a ppi dcx1244 and the bass is head shaking chest vibrating deep, will be deeper and louder when i pick up another matching set of Boston acoustics subs. hope this helps you guys for narrowing down your purchase.
