Guinea pig review

The following review is for R2-W10D4, which is a part of the bundle you are viewing.

It seems I'm the only one that bought these from here lol, but you get what you pay for. Yes they are pricey but they are equivalent to infinity Kappa 93ix 6x9 in terms of crisp and clean. These subs are great so far, I bought them about 9 months ago and just put them in. So I can't speak on durability but great wire connectors that's included and the overall sound is great. If you have the extra money, I suggest getting it. I have 2 10's with the nvx 2000 watt amp running in my 71 Superbeetle. I was running a single 400 watt 10 inch Memphis sub with a 400 watt kicker amp, he did his thing and will again in the future. I just wanted to go back to duals in the bug. It's been since my college days. Buy it, only if you have the funds.

Well worth it!

The following review is for R2-W10D4, which is a part of the bundle you are viewing.

I always been an Alpine man. I went from an S W10D4 to this R W10D4 and I am very happy I did. Bass is nice and on point. I would buy again!
