I bought two of these straight off of sonic electronics and received them around a week later in perfect condition. You can't complain with Sonic Electronix. THE BEST car audio website in my opinion, and i use many many many of them.



If your looking to get into car audio and you want to start out with a really nice set up. My advice would be to go with these alpine type R's. Alpine really makes sure the customer is happy.



The product:

One thing that really confuses people new to car audio may be how much power can this subwoofer really take? It rated peak is 3000 watts. NOW, although alpine does underrate there subs for the safety of you not blowing them, That doesnt mean you go and get a 4000 watt amp. 2 of my R's ran perfect on a 2000 rms amp. The subs always ran cool and never got warm for me once... and im picky about checking that stuff. This sub shines in style. REALLY good looking sub.



The bass!

This is obviously what everyone wants to see. and let me tell you, you cant go wrong with this sub. If you have the money, and are looking to get a quality system. Look no further because this is the one. For 169$ per sub I was blown away at how loud these things were. Along with them being loud the quality of the sub is beautiful. They really punch out clear bass notes. Defiantly a 5 star sub, I still have these currently hooked up in a buddies car and he loves them, never given him a problem for a year and a half.

I initially got the previous model which could handle only 600rms and I cracked the spider so I wanted to get something that could handle more power. This subwoofer put in 1.8cu ported slams lows like I have two 12's in my trunk. PLUS I am only feeding it 3/4 power on my alpine mrp m500. Compared to the previous model this sub is more than worth it.

Alpine Type R is excellent product. The speakers never caused me a problem, they are one of the best subs I ever had. Like I said alpine is an excellent product to buy. Good quality bass.
