    • Sonido impecable
Size: Dual 8" D4 Loaded Enclosure
Completely your audio system! These bass speakers are a real beast inside the car. From the moment you install them, the sound changes completely: the bass becomes deep, powerful and clean, with that rich vibration that only a good subwoofer can give you. It doesn't matter if you listen to reggaeton, trap, electronic, corridos tumbados or bachata with marked bass: these horns respond with impressive strength. The bass punch is sharp and precise. They don't sound "watery" or distort even if you turn up the volume to the maximum. You can see the quality of the cone, the suspension and the coil, which support high power without heating up or losing clarity. ... show more

    • Excellent Build Quality
Size: Dual 12" D4 Loaded Enclosure with Amplifier
This is an amazing all in one package for a beginner with above average install skills. This is not a beginner sound though, I was blown away by the quality and the sound! Very nice finishes and solid craftsmanship. I don't think I could've built this kit myself for the price. Would definitely recommend this 100%. My son is enjoying this as much as I did in my younger days! ... show more

Absolutely unbelievable. I’ve built custom car audio for 30 years. This package deal is amazing. Comes with everything you need except a line out converter. Skar has thought of everything. This kit is well thought out and holy mother of hearing loss does it hammer!

This setup JAMS HARDCORE! Best slam for the buck!! Ive been out of the car audio world for 14 years or so, and wanted to add some bass to my car and a friend reccomended Skar to me. I was just looking for something moderate and I got to say these subs beat my expectations ten-fold. Back years ago when I was into car systems, sealed boxes were the only way to go and I would have never thought ported could slam as hard as these do, they jar my car on the lows and are very loud on higher notes. I had to add two more screws to my licence plate because it makes the trunk lid viberate so strong, they are *seriously* impressive. The amp is nice and powerful, has a selectable 6/12db bass eq, lp and ss filters and includes a bass remote. The system arrived a week earlier than estimated, and they were fortunately unharmed during shipping via fed ex. Nice plus is that the install kit included is the oxygen-free copper set and even included zip ties. They look geat in my car, and the weight of the box keeps them from sliding around so I can leave them unsecured and remove them if I need extra trunk room or to get to the spare tire. I am sold on Skar products, 5 stars from me and I will reccomend them to anyone looking for solid subs from now on. In the future im planning on replacing the rest of my cars speakers with Skar 4ohm 3-ways since my car has a factory amp and already uses 4-ohm drivers. 😎👍 ... show more

    • Boom for buck ratio is insane
Size: Dual 12" D4 Loaded Enclosure with Amplifier
First off, these showed up promptly with no hiccups. My initial impression was that everything seems to be of high quality, the box is really nice and the wiring kit is nicer than a lot I've worked with, probably one of the best ones I've used. A lot of cheap kits claim to be 4 gauge and it's 6 or 8 gauge wire inside a enormous insulator, this was not the case, the wiring is also very flexible which indicates high quality and makes for less hassle when it comes to running the cable. Not gunna lie, when I pulled the amp out of the box and saw how little it was my heart kinda sank, but as soon as it was all hooked up and running it was quickly bounced back into place. These things hit SO HARD and sound SO CLEAN. I'm 100 percent satisfied after running them for 3-4 hours. Something to keep in mind is the box is enormous, it takes up 80 percent of my 08 tsx trunk, the box is about 20% larger than I expected, but it's about 30% louder than I expected it to be, so it still comes out on top. I might swap to 1 12" evl in the future, but as someone who has owned 10 or so "budget" bass setups this setup is incredible for the value. No sticker though! Please send one so I can continue bombing my tool box with things I enjoy! ... show more

Bought the pair of sdr8’s and paired them with the skar 800.1 amp. I am very pleased with the sound these put out. Some people think I got 12s in the back of my suv. They hit hard and low
