Good sounding subs but had issues

Terminal stuck out so far they catch the box, sent me a manual in metric not is standard , cut out online says 7.1 it’s more like 7.25 , had to work terminals to get it to fit and keep tensile leads from being tight, was a real hassle, but they do play and sound good for the money

Great Speaker Great Price

I picked up one SDR-8D2 to replace two PYLE PLPW8D4.
I got a QBomb ported box and a Boss Audio R1100M 1100W Max Class A/B Riot Series Monoblock Car Amplifier.

Everyone that's road in my Escort thinks I either have a pair of 10's or a 12 in the trunk.
I will deffenently recommend Skar to anyone that asks.

I'm going to deck out my Explorer next.

My only con about the SDR-8D2 is, the connectors for the voice coils are wider than a 7.1 cut out. I had to disconnect one sides connectors and reach in through the port to reattach them.

Phenomenal Product, Better Service

I ordered 4 of the SDR-8" subwoofers for a custom build under the back seat of my truck. When ordering, I accidentally ordered the dual 4 ohm instead of the dual 2 ohm and I needed the 2's for the setup we were planning. I had to make a trip down to Tampa anyway and the guys at Skar audio were quick to get me to just swing by and they would swap them out for no additional charge or service fee. The subs and RPK2 Amp only took 2 days to get to me up in Savannah, GA. This company is really on top of their stuff. And the quality of the product is incredible. People are shocked to hear that I'm only using 4- 8" subs for how hard and clear these subs hit!
