wicked amp!

i have this amp powering two 12" svc pioneer subs, 300watts rms each wired to 2 ohms in a 1.68 cubic foot box (for each sub) ported and tuned to 45 hz, and they slam so hard i cant even use my rear veiw mirror anymore, nor my side mirrors! my whole car shakes so much i cant even have a drink in my cup holder without some slpashing out! this amp is way under rated, would recomend to anyone who wants a fair priced amp that rocks very hard and does NOT need an alternator upgrade to power!

im running it with stock 105 amp alternator, new battery and big 3 upgrade with 4 gauge wire and no problems what so ever. and im powering 2 other amps for my 8 speakers also!

also! these things are tough as a rock! i also have the gm-d7500m amp and my trunk leaked a bit (fixed now haha) and when i opened up the trunk, the equivilent of a whole bucket of water spilled dirrectly on top of it, and no sparks, no shorts, no nothing! it was perfeclty fine! like it was right on top of it!

tough as a rock! buy it! you wont be sorry!

Great sound

I bought 2 of these amps to run 2 pioneer 12 inch subs, they work great. Haven't turned them past normal setting and they crank hard. Excellent quality as you expect from pioneer.

Love. Pioneer. Amps.

This pushes my two Infinity Reference 12" subs like they were meant to be - hard and clean! The remote knob is much easier than constantly going into my head unit's menu to adjust the bass as well. I don't know how I ever lived without it.

Great amp! Fits perfectly behind the rear seat in my truck! I have it powering a 10inch Alpine Type-S 1043D and it is a much happier sub with this amp. The bass controll knob is very nice, it doesn't give a "cheep" vibe. I would buy this amp again. I like that it's 2 Ohm stable that gives me room to upgrade the sub without having to upgrade the amp. I have had my System playing at full power for a 2.5 hour drive and the amps never quit once...

Small but powerful

I bought this amplifier to compliment my alpine type r sub. My alpine sub can handle 600 rms and this was the only amplifier that could feed my sub 600 rms for the price that I was willing to pay.

This pioneer amp also satisfied my criteria for being a small amp that delivered a lot of power. I didnt have a lot of room in my extra cab truck, so this small size was definitely a plus. I have this amp nicely tucked away under my seat.

the only downside i can think of that it doesn't have high pass filters, which is what you want in an amp if your sub is enclosed in a vented box. But you can purchase an fmod that attaches onto your rcas to match the hz that your vented box is tuned to.

Picked up one of these bad boys at wal**rt about a year ago. This amp is a beast for the size. 800 watts does not get any more powerful than this.
If you are looking for a good quality amp and a decent price, this is it.

Great amp

Its a great amp but i didnt like it as much cause i wun push my 4 12's and they was only 300 rms and it sounded like garbarge so i just plugged it into my two 12's and they bang the seal around my trunk. I got a 2 door monte carlo.

Great Amp.

I have this amp rockin 2 Renegade GTB2600 subs (both connected by one wire) The sound quality is better that great and the bass it kicks is next level. The bass contoller is a great feature and does get a lot of use.

Great sound

I got this Class D mono-block Amplifier connected to a sub which will deliver in 2 ohms: 600 watts x 1 chan. The sub is a 12" Dual 2 ohm Champion PRO Series Subwoofer Pioneer TS-W3002D2. The sound is GREAT..! The remote bass level control option is really good and needed.

If you are looking for quality this is a good option. Just make sure the Box has the Proper volume. I recommend a sealed box working at 50 db.

Pioneer GM-D8500M & TS-W308D4

This amp, 2 pioneer 12s wired @ 1 OHM in a sealed box (overpowers them) . knocked my rearview mirror off and unbolted my hatch motor right off the car. So loud people complain their ears hurt from the sound pressure. No light dimming, over heating or anything. Next im replacing my stock speakers with pioneer A- Series and a GM-D9500F. PIONEER IS BEST. make sure you do not loose the remote cause without it the output is WEAK
