My first build and love skar audio

So this is my first build ever. I did all the work myself. Took me about 2 months. Did a custom install with the skar rp1500 with a led fan in the side compartment of my tahoe. Built a 10 cf box with baltic birch,triple baffle,my own design box interior with birch and poplar.ebony stain. Cut out a skar logo out of plywood,sanded and painted.clear coated.i did all this with a jig saw and sawzall. installed 2 18" sdr 4ohm subs. Wired to 1 ohm.Installed a 300amp altenator along with the big 3 0 gauge upgrade. My set up hits so hard it makes my chest hurt. My friends can hear me coming a few blocks away.Im definitely impressed and will be a skar customer for life.

Amazing Sub!!

I have had this installed in my 04 Grand Cherokee for about 2 weeks and I am very impressed! Could not ask for a better deal for this price!

Infinite Baffle

I put two of these in my car in infinite baffle and they hit hard! I can play them down to 19 hrz as well on 550rms total. 120db+ all across and people can hear you across a large intersection if that's your thing. What I really love is when they barely play and appear not to move but sound good tonality wise.
They responded respectable on fast kick drums to, could be a bit faster but 18's but don't get me wrong as most people won't notice.
Love skar, price to performance is off the charts. I just need to replace my 6x9s with 8" mids and I'll be very happy with Skar products all the way around!

Misleading on website, subs look great.

Part of my reason for choosing Skar SDR's over CT Sounds Tropo's was on Soars website it says under voice coil "copper" but on the retail box they came shipped in it states "CCAW" copper clad aluminum wire. That is NOT copper ! The other part for choosing Skar was the 2yr vs 90 day warranty. Hopefully the CCAW will hold up without toasting. The subs do look amazing and we'll built for the money. I gave 3 stars as a neutral review until I get the box done and fired up.
