i have the alpine mrp m450. The first subs i had were shitty legacy subs i got which blew on me. i was wondering if you guys would tell me what kinda subs i should get which will produce good quality sound and wont blow. im looking for probably just 1 12" sub. here are my amps spec

Details:

» mono subwoofer car amplifier
» 220 watts RMS x 1 at 4 ohms (400 watts RMS x 1 at 2 ohms)
» variable low-pass filter (50-200 Hz, 24 dB/octave)
» tuned Bass EQ (0-12 dB bass boost at 50 Hz)
» subsonic filter (15 Hz, 24 dB/octave)
» MOSFET power supply
» CEA-2006 compliant
» STAR Topology (minimizes internal noise and prevents ground interference)
» speaker- and preamp-level inputs
» gold-plated screw terminals
» fuse rating: 20A x 2
» 8-gauge power and ground leads recommended — wiring and hardware

if i was you i would get a 12" Alpine Type R....Dual 4 Ohm VC and wire them into 2 ohm.....should be pretty loud for 400 watts....then again those subs can take 700 w rms easily...

hehe... everyone loves the Type-R ... even when it comes to speakers

Not a bad choice... the Kicker CVR's are also good and can be had for a very good price too.

there is a reason everyone loves them ... find another sub online that can be had for under 100$ US and take well over its rated 500 watts rms

Type-R's are good.. so are Type-S's
take a look at JL 12w3

I would say any sub which is 4-0hm DVC and about 400-600 RMS should be fine. Looking into Kicker CVR's or Alpine Type R's

If you were up in the air about choosing a sub between a Alpine or Kicker CVR. My vote would be with Jordy O on this one. The CVR all the way. IMO the kicker products have always out lasted the Alpine subs. And there are lots of subs that can be had for under $100.

which kicker cvr model would u recommend for me?

I agree about the Kicker Comp VR much better driver IMO. yes the alpine sub is 500 RMS, but I mean if everyone looked at power-rating for price........wouldn't everyone be running audiobhan subs? I mean they boast quite the RMS ratings for even their entry level subwoofers. Having worked at a shop who carried audiobhan for a little bit, the subs are designed very week and generally can't take what their rated for.

my opinion from working with both speakers in comparison. The Kicker has better overall response to my ears than the alpine, and was able to reproduce lower freqencies without botteming out.

if you wanted to go with the Kicker sub either look for a CompVR in a single 4 ohm voice coil or dual 2 ohm configuration to get max performance out of your amplifier.

You will need a Kicker CVR with dual 4 ohm coils the part number is 05CVR124.

His amp produces full power at 2 ohm mono.

your right, i misread that in his original post. You need either a single 2 ohm sub which I doubt they make in the CVR. Or as listed in the previous post. Dual 4 ohm to get max out of your amp (2ohm mono 400 RMS)
