help, with my amp and my subwoofers

[Neto MC]

Hi there, well I was going to upgrade my car audio system, I already have a Kicker CVR 12" -4 ohms , of 400 RMS, with a amplifier Sony, but I wanted to get the pair of the sub, for having more bass, and also that mean to get a more powerfull amplifier, but I make and internet bought, to get the exactly pair of subwoofer Kicker CVR 12" same model, but now they told me that they don't have it any more, and they offer me, this Kicker CompR 12" 4 ohms, and this one gives me 100 RMS more than the CVR 12" that I already have.

And I don´t know if I run on the same amplifier, is going to give me problems like, overheating, or that I don´t get a really good bass, because they are different models, I don't know if that could give me like the bass waves of CompR, suppressed the CVR that is 100 RMS lower.

Because one time in my audio car beginnings, I out 2 different amplifiers, one Sony, and other Memphis, and " different subs one JL Audio WXv2, and my Kicker CVR 12", and both subs in different enclosures, with different HZ, and sizes, so I had an lil bit streamer sound, but I lose a lot Sound quality, so I took of the JL audio.

So If I put this 2 subwoofers the Kicker´s on a same amp, and on same boxes, or enclosures. my sound waves will be good, or is really important to have the exactly pair of subwoofer.

thanks for your time, I will be very grateful for your advice's,

If using two different subwoofers, use separate enclosures, or a single enclosure that completely seals the subwoofers off from one another. I would also suggest different amplifiers.
