I just picked up 2 Alpine Type E 12s to replace my old Lanzars. I am thinking of buying a Kenwood KAC 7201 amp to power them. What are your thoughts on this? The 12s are in a sealed box, I think 1.5 cubic ft per chamber, maybe 1.75.

I have the same amp for my single sub setup. If you can put a 2 ohm stereo load on it you shoud be able to get around 230 watts per sub (around that amount area).

Cool, that's what I was planning. In order to do so I only need to run my subs parallel correct?

IF I'm not mistaken, the Type E subs are single 4 ohm voice coils so if you wire the both subs in parallel to one channel it should work.

The Type E series are 4ohm SVC's. 200RMS 600Peak

If you wire them in parallel you will end up with a 2ohm total load. Since the KAC-7201 is not 2ohm Mono stable, your only choices with that amp are:
1) Wire both speakers in parallel to 1 channel (not a bridge, just use 1 channel) for apx 200 watts total (100 per sub). The amp is rated 230 x 2 @ 2ohms, but that is based on a 14.4 volt electrical system, not a 12 volt system.
2) Wire each sub independantly on it's own channel for apx 125 watts per sub.

You would be better off finding a 2ohm stable Class D Mono amp rated at least 400 x 1 @ 2ohms. If you're on a budget, the JBL BP600.1 would work nicely. On a 12 volt system you would get apx 550 watts total, or 275 watts per sub. You would be a lot happier. Just a thought...

wvsquirrel is right, you'd only get 100 watts per sub with a 2 ohm load. My MIstake

Well, thanks for all the responses, I ended up going w/ the Kenwood Amp, found a good deal on it via Ebay. I looked at the JBL amp as well but it was a bit too expensive.

My next step is going to be a component setup. I will probably go w/ the Alpine Type R's based on decent prices from Ebay as well. Plus we all know they are great speakers.

Right now I am using 2 Boss tweeters but the amp is no longer working. It's a piece of sh*t Optimus that someone gave me. I want to get rid of the Boss tweeters, that's why I am going w/ the Type R's. What would be a good amp to use w/ the 6.5's and the tweeters?

Thanks again for all the responses!
