The combo pack sucks

I got the 8s combo pack with amp and wiring kit these 8s suck i warranty one out and now another one is not working i get my stuff installed at best buy and after taking everything apart its loaded in a series and theres alot of rms left on the table filling the triple box with the SVRs will be perfect and also having a wire terminal for each sub will be perfect. I am currently going thru the process of going thru warranty for a second subwoofer but I highly doubt they will replace a second one after the first one

Big bass in a small package

I was pleasantly surprised by these little things. I put them in 2 invidual boxes i had sitting around the house just to use until i build a box and SHEESH. I put them on a RP-1500.1DM. Definitely overpowering them but i got the gain down.
