Awsome amplifiers!! Two powering four fsx 10,four fsx 8 ,four fsx 6.5 and four 3.5
RP-150.4 AB is the best for entry level
Bought this amp two weeks ago and installed in one day. Running four FSX-65s and four SPX-T 1” tweeters. Two of each per door. They sound mad clean and LOUD! By all means I was impressed and that takes a lot. I’ll be a returning customer
Clean with lots of power
Got this on front and rear set of ds-18s 6.5s and horn drivers and its loud enough that it hurts.
One week in.
So far so good, only using 2 channels atm but its been pretty solid no issues yet.
