Customer Ratings & Reviews

good product

Really stops the rattling that comes from having the punch from the kiker speakers i have installed in the doors of my car.

Easy to use and apply

I used this product in my rear component speakers (Alpines) for the mid-range woofers in the doors to shield against vibration and they do a good job and the speakers sound great for it!

Cache CSM

These came in a package deal from Sonic
with JBL GTO series speakers one of the decisions why I bought the GTO speakers, easy to use. Currently installing the sound system but having used similar products before these will make a good speaker sound better.

Great product

Worked good, stopped the rattling. Deeper bass.

good stuff!

I bought this in a combo package that Sonic put together with a set of hifonics components, the zxi65c. i liked it, i havent heard any rattling from my speakers. works well, i recommend it.

Sounds Great!

I installed the Dead Shield Sound Dampening Material under all 4 of the speakers I replaced in my truck and the stereo system sounds great, better than I expected.

SE35's are pretty sweet!

I put these in to replace the factory Boston system in my '05 WK Jeep. The SQ is a night/day difference! Clean highs and lows and they're running just fine on my stock Boston amp. In the future, I'll be upgrading the amp to something with a little bit more power, but these still get loud with little/no distortion. If you're replacing OEM, look no further. Also, I compared these head to head with the Infinity Reference series. Although these are a bit more expensive, they're DEFINITELY worth the premium price. Infinity = budget, Boston = quality on a budget.

sound great but get frequency blockers!

Highs are really nice for coaxials, but bass blockers are highly recommended. any amount of bass and snap crackle pop from the 3 1/2 inch cone

Boston Accoustics

Very good quality sound. Loud, crisp sound. replace all your car speakers with Boston Acoustics. Sonic Electronix has the best price. If you want high sound quality Boston Acoustics is the best.

Good Quality Speaker

I put these in the dash of my 2005 Chrysler 300 running off of the deck power from my Sony navigation system. I think the speakers have a nice clear sound and would recommend to anyone looking for a good sounding pair of dash speakers.

Big Improvement

I have a 2006 Chrysler 300 with the factory radio. It made lots of sizzle and boom noise but there was gaping holes in the music. I replaced the front dash speakers with the SE35s and it made a huge difference. The factory speakers were 8 ohm cardboard toy speakers from mexico like you'd find in an old cheap japanese tranistor radio. The factory radio hasn't blown yet with the reduced resistance as the dash speakers are wired in parallel with the door speakers. I put 6 x 9 boston acoustic speakers in the back shelf too. I got a lot cleaner sound but lost some of the bass boom. I just run the bass boost very high now. This is highly recommended for a cheap big improvement to the stock system. Pretty easy to install.
