The following review is for T1675-S, which is a part of the bundle you are viewing.

Just installed these and holy cow... what a difference. Had jl c5-650 and these rockford fosgate speakers blow them out of the water. Even better they were half the price of jl you cant go wrong! Buy them!!!

clear from min to max

The following review is for T1675-S, which is a part of the bundle you are viewing.

installed on a jetta mk4. Needed spacers but beyond that the install was easy. I mounted the crossovers in the trunk because they are kind of big but i knew that going in and they do there job well. clear highs and lows from min to max. If you want it loud then this is for you.

Amazing speakers

The following review is for T1675-S, which is a part of the bundle you are viewing.

I immediately installed them and hooked them up to my P400-4 amp in my truck and they sound astonishing. Crystal clear at any volume. Highly recommended if you've got the room for them. Since they're 6 3/4" speakers they may not fit into 6 1/2" openings, but with them being components and the tweeters and crossovers have to be mounted separately that should be something expected when ordering.

Best Speakers Ever

The following review is for T1675-S, which is a part of the bundle you are viewing.

Holy cow beautifull and loud highs. Lows, mids all in perfect harmony and surprisingly you can FEEL a decent amount of bass coming from this mid woofer. Very impressive, crank it up and is still crystal clear. Only downside i can see from these is finding a spot for the massive crossover that comes with them. If your looking for some bass great mid bass/mids and highs that are SUPER loud but not harsh sounding these are where its at right here you will not be disappointed. BUY THESE!!!

Loud and Clear

The following review is for T1675-S, which is a part of the bundle you are viewing.

I have these on a Hifonics 1000.4 amplifier. They are getting 125watts RMS each and sound amazing. Have gotten many compliments on them. People say they can hear me coming around of the block. The woofer is like a mini subwoofer. It flexes my door a little bit too. And of course its the classic Rockford quality you expect. Am very happy with them and would recommend them to anyone. Would be nice if the crossover was a bit smaller though. They don't distort. Not even at the highest volume on my deck. Get em. You won't regret it. Rockford Fosgate is the best.

Very very good

The following review is for T1675-S, which is a part of the bundle you are viewing.

This get loud easy, clear as a bell too! Im running these active and not using the passive crossovers.. Only drawback i noticed is the favor the 1khz range a bit too much. You can fix this by giving the tweeters more power and or eq-ing that range down a bit. but then they get a bit too bright. Having a midbass driver to pair with these would help a lot as these are not meant for midbass frequencies. Overall I'm very very happy with them. Would recommend.

Great Speakers!

The following review is for T1675-S, which is a part of the bundle you are viewing.

I have stated on many other reviews how much I am a Rockford Fosgate fan and this component set makes it even easier for me to continue to make that claim. They sound great and don't give any issue despite the power I am putting on them (a RF Power T400X2ad, with 200w rms per channel),...and I crank my system for astraight hour, each way, to work!
