Rockford Fosgate P1692C

Hey guys, juste bought myself a pair of 9x6 at BestBuy (Liquidation) for a rly good price, almost half price!! Now.. i installed them.. and beleive it or not.. it has much lower base and sound quality than my old stock rear deck speakers... My car is a Buick ParkAvenue 94, and my head unit is a Clarion DXZ555MP which has 4x52W.

The R-F is 75w RMS and 150 Max...

I am thinking of returning them.. or should i keep em and save for an amp? Because i dont have an amp.

They cost me 79$ Canadian, down from 149.99 .

I used my stock speaker wire (soldered the wires on the connections) because they are thicker, lower gage.

I just need to know if they are good speakers to have.

Any sugestions guys?
