Sounds good but it sounds awesome with SDR-8

So I’ve had this tube system for about 6 months running with a 350.1 skar amp. I was unable to put to much gain before it would start popping and having issues. The bass was efficient but I thought it could be better. So I went and purchased a SDR-8 D2 and replaced the sub out. The technique is very easy, the grill comes off easy and the speaker is held in with hex key machine screws. Wired the SDR-8 the same as the old sub to 1 ohm. Putting the screws back were a little tight on the new sub but it worked without have to drill the holes bigger. Tested it after completion and what a big difference, and that is with low gain for the break in period. Attached pictures of sub difference and box quality. SDR-8 Is on the right

Skar Bass Tube

The Skar Bass Tube is amazing, it hits hard for the size. I’m pushing it with a Skar 1200W amp, and the set up couldn’t work better. Very satisfied with this purchase.

Skar Audio SK8TBV Single 8" 400 Watt Loaded Vented Subwoofer Bass Tube Review

The construction is solid and very well designed. The thump is crisp and clear. The look of the box is very elegant with the Skar logo in silver over black. Installed this in the trunk of my 2016 Hyundai Genesis to add to the lack of bass from the original Stereo System.

Big bass in a small package!

This sub sounds great and has big bass for an 8” sub!
