Mono amp suggestion to drive single Polk MM 10"?

[redline9k]

Updating a 2013 Audi A4 and first step is a sub. Im going to move an Audio Control LC6i and the 10" MM over from the old car, but my old amp was a 6ch so ill need a new mono amp.

What would you guys recommend? It will be a sealed box, nothing ridiculous, just clean and middle of the road quality (Alpine, JL, etc).

Is is 4 ohm, 2 ohm? Can you post the model of the sub?

Is the sub a dual 4 or single 4? If single I'd get a cheap 2 channel and run it bridged. I run my 15" Polk MM off this: Pioneer GM-5400T 2-channel car amplifier — 125 watts RMS x 2 at Crutchfield.com When you upgrade the door speakers later you'll already have a 2 channel then you can buy a monoblock.

its the single vc...mm1040 (*printed* 350RMS).

Hm, maybe no mono for me?....man ive been out of this for too long. Anyway, ok, how about a good quality 2/4ch bridgeable amp dedicated to sub use for now? Im good up to about 4-500 bucks for the amp not including wiring etc (glad to spend less if i dont have to)

JBL GTO-501EZ, 350W RMS x 1. You're a long way off from $400-500 and don't lose a wink of sleep over it. I don't use 2-channel amps on subs.

Audio technix 400.1 on eBay for 120 shipped. NIB.

GREAT DEAL!!!!!!!!

the JBL looks pretty good to me. FWIW, ive had that MM1040 and LC6i for awhile now....should I consider upgrading or are they still at least better-than-average by current standards?

LC6i is a current product. If you like the subwoofer keep using it.

Is still get a mono block amp. It will leave room for better subs or sub in the future

FYI to the original poster, mono subwoofer amplifiers are commonly class D, which is far more efficient than class AB 2 or 4 channel designs. That means less heat dissipation, less current draw and more power for the dollar, since class D designs are cheaper to manufacture than class AB. Class D topologies are harder to get clean at higher frequencies, but low frequencies are easier to make happen.

Suggested; acquire a simple 2 + 1 mono amp like the Massive Audio NX3, where you get a compact 2 channel stereo amplifier and a single subwoofer channel all in the same chassis. I believe several of the board sponsors sell this, or similar amplifiers at around $200. There's no reason to get anywhere near $400.
