Look into the Hifonics line up of amplifiers.

How about a JL Audio 1000/1 you will have to keep the gain down a little, [1000W RMS]... http://mobile.jlaudio.com/prod...d=221 there are more then a few at eBay for around $500 or less, [used] 94

Boston Acoustics GT-24. ~900-1000rms @ 2ohm

Had that amp in my car for the last year and love it. Plenty of power even @ 4ohm.

Orrrrrr an alpine MRDM1005 (power @ 2ohm), Orrrrrr a diamond audio D3800.1 (if you can wire those subs down to 1ohm) or a kenwood KACX812D (underpowered unless you run @ 1ohm). What impedance are your woofers?

That Boston Acoustics is only 175watt/channel. however the alpine looks tasty. BTW how would i wire my subs for 1 ohm? can u tell im kinda a dumbass when it comes to electronics?

That boston is rated at 500rms @ 4ohm bridged or 900rms @ 2ohm bridged. I ran those 900rms to a 450rms sub for a long time and never had a problem with it. Good, clean, and loud

Imo as long as you have clean power it is rather difficult to overpower a speaker

Just keep your gains conservative and you'll be fine. I like to get amp and deck gains below 80%

You can not wire two 4 ohm speakers to a 1 ohm load, if you wire them in parallel you get a 2 ohm load, if you wire them in series you get a 8 ohm load. 94

Too much heat, too much excursion will send your sub into eternal sleep...with good, clean power That's the point of no return Keep your gains down and waste the extra watts you paid for
